Abstract
El controlador de vistas de extensión no valida los datos enviados desde la aplicación host.
Explanation
La extensión recibe los datos de la aplicación host en su controlador de vistas y no implementa SLComposeServiceViewController isContentValid para validar los datos que no son de confianza antes de usarlos.

Ejemplo 1: el siguiente controlador de vistas de extensión recibe datos de la aplicación host pero no implementa un método de devolución de llamada para validarlos:


#import <MobileCoreServices/MobileCoreServices.h>

@interface ShareViewController : SLComposeServiceViewController
...
@end

@interface ShareViewController ()
...
@end

@implementation ShareViewController

- (void)didSelectPost {
NSExtensionItem *item = self.extensionContext.inputItems.firstObject;
NSItemProvider *itemProvider = item.attachments.firstObject;
...
// Use the received items
...
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}

...

@end

desc.structural.swift.insecure_ipc_missing_content_validation
Abstract
La aplicación no puede verificar el remitente de una llamada de comunicación entre procedimientos (IPC) basada en URL.
Explanation
Cuando una aplicación de terceros o webview usa una URL para comunicarse con su aplicación, la aplicación receptora debe verificar que el remitente coincida con la lista de aplicaciones permitidas que se espera que se comuniquen con esta. La aplicación receptora tiene la opción de verificar el origen de la URL de llamada mediante los métodos de delegación UIApplicationDelegate application:openURL:options: o UIApplicationDelegate application:openURL:sourceApplication:annotation:.

Ejemplo 1: la siguiente implementación del método de delegación UIApplicationDelegate application:openURL:options: no verifica el remitente de la llamada de IPC y simplemente procesa la URL de llamada:


- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
NSString *theQuery = [[url query] stringByRemovingPercentEncoding:NSUTF8StringEncoding];
NSArray *chunks = [theQuery componentsSeparatedByString:@"&"];
for (NSString* chunk in chunks) {
NSArray *keyval = [chunk componentsSeparatedByString:@"="]; NSString *key = [keyval objectAtIndex:0];
NSString *value = [keyval objectAtIndex:1];
// Do something with your key and value
}
return YES;
}

Explanation
Cuando una aplicación de terceros o webview usa una URL para comunicarse con su aplicación, la aplicación receptora debe validar la URL que efectúa la llamada antes de realizar más acciones. La aplicación receptora tiene la opción de verificar si desea abrir la URL de llamada mediante los métodos de delegación UIApplicationDelegate application:didFinishLaunchingWithOptions: o UIApplicationDelegate application:willFinishLaunchingWithOptions:.

Ejemplo 1: la siguiente implementación del método de delegación UIApplicationDelegate application:didFinishLaunchingWithOptions: no valida la URL de llamada y siempre procesa la URL que no es de confianza:


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
return true
}

Abstract
La aplicación usa esquemas de URL personalizados para la comunicación entre procedimientos (IPC), que está sujeta al "secuestro de esquemas de URL".
Explanation
Las aplicaciones pueden registrar esquemas de URL personalizados para que las aplicaciones de terceros se comuniquen con ellos. Si bien este es un canal de IPC simple, puede exponer a su aplicación al "secuestro de esquemas de URL". Debido a que cualquier aplicación puede registrar un esquema de URL con la condición de que no esté reservado por Apple, una aplicación malintencionada puede registrar el mismo esquema utilizado por su aplicación, lo que provoca un comportamiento indefinido. De acuerdo con la documentación de Apple: "Si más de una aplicación de terceros se registra para controlar el mismo esquema de URL, actualmente no hay ningún proceso para determinar qué aplicación recibirá ese esquema". Si la aplicación malintencionada se instala antes que su aplicación, podrá registrar el esquema y evitar que su aplicación se instale correctamente. Por otro lado, si la aplicación malintencionada se instala después de su aplicación y logra registrar el esquema, podrá secuestrar su aplicación.

Abstract
Los generadores de números pseudoaleatorios estándar no pueden soportar ataques criptográficos.
Explanation
Cuando se utiliza una función que puede producir valores predecibles como un origen de aleatoriedad en un contexto de seguridad, se producen errores de aleatoriedad no segura.

Los equipos son máquinas deterministas y como tales no pueden producir una aleatoriedad auténtica. Los generadores de números pseudoaleatorios (PRNG, Pseudorandom Number Generator) aproximan la aleatoriedad de forma algorítmica, a partir de un valor de inicialización desde el que se calculan los valores siguientes.

Existen dos tipos de PRNG: estadísticos y criptográficos. Los PRNG estadísticos proporcionan propiedades estadísticas útiles, pero su resultado es altamente predecible y crea una secuencia numérica fácil de reproducir que no es adecuada para aquellos casos en los que la seguridad dependa de que los valores generados sean impredecibles. Los PRNG criptográficos resuelven este problema mediante la generación de resultados que sean más difíciles de predecir. Para que un valor sea criptográficamente seguro, debe ser imposible o altamente improbable para un usuario malintencionado distinguir entre el valor aleatorio generado y un valor verdaderamente aleatorio. Por lo general, si un algoritmo PRNG no se anuncia como criptográficamente seguro, es probable que se trate de un PRNG estadístico y no debería usarse en contextos relativos a la seguridad en los que su uso podría provocar vulnerabilidades graves, como contraseñas temporales fáciles de adivinar, claves criptográficas predecibles, secuestro de sesiones y suplantación de identidad DNS.

Ejemplo 1: El siguiente código utiliza un PRNG estadístico para crear una dirección URL de un recibo que permanece activo durante un período de tiempo después de una compra.


FORM GenerateReceiptURL CHANGING baseUrl TYPE string.
DATA: r TYPE REF TO cl_abap_random,
var1 TYPE i,
var2 TYPE i,
var3 TYPE n.


GET TIME.
var1 = sy-uzeit.
r = cl_abap_random=>create( seed = var1 ).
r->int31( RECEIVING value = var2 ).
var3 = var2.
CONCATENATE baseUrl var3 ".html" INTO baseUrl.
ENDFORM.


Este código utiliza la función CL_ABAP_RANDOM->INT31 para generar identificadores "únicos" para las páginas de recibos que crea. Como CL_ABAP_RANDOM es un PRNG estadístico, es fácil que un usuario malintencionado adivine las cadenas que genera. Aunque el diseño subyacente del sistema de recepción también es defectuoso, sería más seguro si utilizara un generador de números aleatorios que no generase identificadores de recibos predecibles, como un PRNG criptográfico.

Abstract
Los generadores de números pseudoaleatorios estándar no pueden soportar ataques criptográficos.
Explanation
Cuando se utiliza una función que puede producir valores predecibles como un origen de aleatoriedad en un contexto de seguridad, se producen errores de aleatoriedad no segura.


Los equipos son máquinas deterministas y como tales no pueden producir una aleatoriedad auténtica. Los generadores de números pseudoaleatorios (PRNG, Pseudorandom Number Generator) aproximan la aleatoriedad de forma algorítmica, a partir de un valor de inicialización desde el que se calculan los valores siguientes.

Existen dos tipos de PRNG: estadísticos y criptográficos. Los PRNG estadísticos proporcionan propiedades estadísticas útiles, pero su resultado es altamente predecible y crea una secuencia numérica fácil de reproducir que no es adecuada para aquellos casos en los que la seguridad dependa de que los valores generados sean impredecibles. Los PRNG criptográficos resuelven este problema mediante la generación de resultados que sean más difíciles de predecir. Para que un valor sea criptográficamente seguro, debe ser imposible o altamente improbable para un usuario malintencionado distinguir entre el valor aleatorio generado y un valor verdaderamente aleatorio. Por lo general, si un algoritmo PRNG no se anuncia como criptográficamente seguro, es probable que se trate de un PRNG estadístico y no debería usarse en contextos relativos a la seguridad en los que su uso podría provocar vulnerabilidades graves, como contraseñas temporales fáciles de adivinar, claves criptográficas predecibles, secuestro de sesiones y suplantación de identidad DNS.

Ejemplo 1: El siguiente código utiliza un PRNG estadístico para crear una dirección URL de un recibo que permanece activo durante un período de tiempo después de una compra.


<cfoutput>
Receipt: #baseUrl##Rand()#.cfm
</cfoutput>


Este código utiliza la función Rand() para generar identificadores "únicos" para las páginas de recibos que crea. Como Rand() es un PRNG estadístico, es fácil que un usuario malintencionado adivine las cadenas que genera. Aunque el diseño subyacente del sistema de recepción también es defectuoso, sería más seguro si utilizara un generador de números aleatorios que no generase identificadores de recibos predecibles, como un PRNG criptográfico.

rsa.GenerateKey(mathRand, 2048)


Este código utiliza la función rand.New() a fin de generar aleatoridad para una clave RSA. Como rand.New() es un PRNG estadístico, es fácil que un atacante adivine los valores que genera.

Abstract
Los generadores de números pseudoaleatorios estándar no pueden soportar ataques criptográficos.
Explanation
Cuando se utiliza una función que puede producir valores predecibles como un origen de aleatoriedad en un contexto de seguridad, se producen errores de aleatoriedad no segura.

Los equipos son máquinas deterministas y como tales no pueden producir una aleatoriedad auténtica. Los generadores de números pseudoaleatorios (PRNG, Pseudorandom Number Generator) aproximan la aleatoriedad de forma algorítmica, a partir de un valor de inicialización desde el que se calculan los valores siguientes.

Existen dos tipos de PRNG: estadísticos y criptográficos. Los PRNG estadísticos proporcionan propiedades estadísticas útiles, pero su resultado es altamente predecible y crea una secuencia numérica fácil de reproducir que no es adecuada para aquellos casos en los que la seguridad dependa de que los valores generados sean impredecibles. Los PRNG criptográficos resuelven este problema mediante la generación de resultados que sean más difíciles de predecir. Para que un valor sea criptográficamente seguro, debe ser imposible o altamente improbable para un usuario malintencionado distinguir entre el valor aleatorio generado y un valor verdaderamente aleatorio. Por lo general, si un algoritmo PRNG no se anuncia como criptográficamente seguro, es probable que se trate de un PRNG estadístico y no debería usarse en contextos relativos a la seguridad en los que su uso podría provocar vulnerabilidades graves, como contraseñas temporales fáciles de adivinar, claves criptográficas predecibles, secuestro de sesiones y suplantación de identidad DNS.

Ejemplo 1: El siguiente código utiliza un PRNG estadístico para crear una dirección URL de un recibo que permanece activo durante un período de tiempo después de una compra.


function genReceiptURL (baseURL){
var randNum = Math.random();
var receiptURL = baseURL + randNum + ".html";
return receiptURL;
}


Este código utiliza la función Math.random() para generar identificadores "únicos" para las páginas de recibos que crea. Como Math.random() es un PRNG estadístico, es fácil que un usuario malintencionado adivine las cadenas que genera. Aunque el diseño subyacente del sistema de recepción también es defectuoso, sería más seguro si utilizara un generador de números aleatorios que no generase identificadores de recibos predecibles, como un PRNG criptográfico.

Este código utiliza la función DBMS_RANDOM.SEED() para generar identificadores "únicos" para las páginas de recibos que crea. Como DBMS_RANDOM.SEED() es un PRNG estadístico, es fácil que un usuario malintencionado adivine las cadenas que genera. Aunque el diseño subyacente del sistema de recepción también presenta errores, sería más seguro si utilizase un generador de números aleatorios que no crease identificadores de recepción predecibles.

Abstract
Los generadores de números pseudoaleatorios estándar no pueden soportar ataques criptográficos.
Explanation
Cuando se utiliza una función que puede producir valores predecibles como un origen de aleatoriedad en un contexto de seguridad, se producen errores de aleatoriedad no segura.

Los equipos son máquinas deterministas y como tales no pueden producir una aleatoriedad auténtica. Los generadores de números pseudoaleatorios (PRNG, Pseudorandom Number Generator) aproximan la aleatoriedad de forma algorítmica, a partir de un valor de inicialización desde el que se calculan los valores siguientes.

Existen dos tipos de PRNG: estadísticos y criptográficos. Los PRNG estadísticos proporcionan propiedades estadísticas útiles, pero su resultado es altamente predecible y crea una secuencia numérica fácil de reproducir que no es adecuada para aquellos casos en los que la seguridad dependa de que los valores generados sean impredecibles. Los PRNG criptográficos resuelven este problema mediante la generación de resultados que sean más difíciles de predecir. Para que un valor sea criptográficamente seguro, debe ser imposible o altamente improbable para un usuario malintencionado distinguir entre el valor aleatorio generado y un valor verdaderamente aleatorio. Por lo general, si un algoritmo PRNG no se anuncia como criptográficamente seguro, es probable que se trate de un PRNG estadístico y no debería usarse en contextos relativos a la seguridad en los que su uso podría provocar vulnerabilidades graves, como contraseñas temporales fáciles de adivinar, claves criptográficas predecibles, secuestro de sesiones y suplantación de identidad DNS.

Ejemplo 1: El siguiente código utiliza un PRNG estadístico para crear una dirección URL de un recibo que permanece activo durante un período de tiempo después de una compra.


def genReceiptURL(self,baseURL):
randNum = random.random()
receiptURL = baseURL + randNum + ".html"
return receiptURL


Este código utiliza la función rand() para generar identificadores "únicos" para las páginas de recibos que crea. Como rand() es un PRNG estadístico, es fácil que un usuario malintencionado adivine las cadenas que genera. Aunque el diseño subyacente del sistema de recepción también es defectuoso, sería más seguro si utilizara un generador de números aleatorios que no generase identificadores de recibos predecibles, como un PRNG criptográfico.

Abstract
Los generadores de números pseudoaleatorios estándar no pueden soportar ataques criptográficos.
Explanation
Cuando se utiliza una función que puede producir valores predecibles como un origen de aleatoriedad en un contexto de seguridad, se producen errores de aleatoriedad no segura.

Los equipos son máquinas deterministas y, como tales, no pueden producir una aleatoriedad auténtica. Los generadores de números pseudoaleatorios (PRNG, Pseudorandom Number Generator) aproximan la aleatoriedad de forma algorítmica, a partir de un valor de inicialización desde el que se calculan los valores siguientes.

Existen dos tipos de PRNG: estadísticos y criptográficos. Los PRNG estadísticos proporcionan propiedades estadísticas útiles, pero su resultado es altamente predecible y crea una secuencia numérica fácil de reproducir que no es adecuada para aquellos casos en los que la seguridad dependa de que los valores generados sean impredecibles. Los PRNG criptográficos resuelven este problema mediante la generación de resultados que sean más difíciles de predecir. Para que un valor sea criptográficamente seguro, debe ser imposible o altamente improbable para un usuario malintencionado distinguir entre el valor aleatorio generado y un valor verdaderamente aleatorio. Por lo general, si un algoritmo PRNG no se anuncia como criptográficamente seguro, es probable que se trate de un PRNG estadístico y no debería usarse en contextos relativos a la seguridad en los que su uso podría provocar vulnerabilidades graves, como contraseñas temporales fáciles de adivinar, claves criptográficas predecibles, secuestro de sesiones y suplantación de identidad DNS.

Ejemplo 1: El código siguiente usa un PRNG estadístico para crear un valor aleatorio que se usa como token de restablecimiento de contraseñas.

Ejemplo 1: El siguiente código utiliza un PRNG estadístico para crear una dirección URL de un recibo que permanece activo durante un período de tiempo después de una compra.


...
Function genReceiptURL(baseURL)
dim randNum
randNum = Rnd()
genReceiptURL = baseURL & randNum & ".html"
End Function
...


Este código utiliza la función Rnd() para generar identificadores "únicos" para las páginas de recibos que crea. Como Rnd() es un PRNG estadístico, es fácil que un usuario malintencionado adivine las cadenas que genera. Aunque el diseño subyacente del sistema de recepción también es defectuoso, sería más seguro si utilizara un generador de números aleatorios que no generase identificadores de recibos predecibles, como un PRNG criptográfico.

Abstract
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante.
Explanation
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante. Si un generador de números pseudoaleatorios (como la clase CL_ABAP_RANDOM o sus variantes) se inicializa con un valor constante específico, los valores devueltos por GET_NEXT, INT y métodos similares que devuelven o asignan valores son predecibles para un atacante que puede recopilar varios resultados de PRNG.

Ejemplo 1: En el siguiente extracto de código, los valores que produce el objeto random_gen2 son predecibles desde el objeto random_gen1.


DATA: random_gen1 TYPE REF TO cl_abap_random,
random_gen2 TYPE REF TO cl_abap_random,
var1 TYPE i,
var2 TYPE i.

random_gen1 = cl_abap_random=>create( seed = '1234' ).

DO 10 TIMES.
CALL METHOD random_gen1->int
RECEIVING
value = var1.

WRITE:/ var1.
ENDDO.

random_gen2 = cl_abap_random=>create( seed = '1234' ).

DO 10 TIMES.
CALL METHOD random_gen2->int
RECEIVING
value = var2.

WRITE:/ var2.
ENDDO.


En este ejemplo, los generadores de números pseudoaleatorios: random_gen1 y random_gen2 se inicializaron de forma idéntica, por lo que var1 = var2

Abstract
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante.
Explanation
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante. Si un generador de números pseudoaleatorios (como rand()) se inicializa con un valor específico (mediante una función como srand(unsigned int)), los valores devueltos por rand() y métodos similares que devuelven o asignan valores son predecibles para un usuario malintencionado que puede recopilar varios resultados de PRNG.

Ejemplo 1: Los valores que produce el generador de números pseudoaleatorios son predecibles en los dos primeros bloques porque ambos comienzan con el mismo valor de inicialización.


srand(2223333);
float randomNum = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum);
randomNum = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum);

srand(2223333);
float randomNum2 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum2);
randomNum2 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum2);

srand(1231234);
float randomNum3 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum3);
randomNum3 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum3);


En este ejemplo, los resultados de randomNum1 y randomNum2 se inicializan de manera idéntica, de modo que cada llamada a rand() después de la llamada que inicializa el generador de números pseudoaleatorios srand(2223333) producirá los mismos resultados en el mismo orden de llamada. Por ejemplo, la salida podría ser parecida a esta:


Random: 32.00
Random: 73.00
Random: 32.00
Random: 73.00
Random: 15.00
Random: 75.00

Abstract
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante.
Explanation
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante. Si un generador de números pseudoaleatorios (PRNG) se inicializa con un valor específico (usando funciones como math.Rand.New(Source)), los valores devueltos por math.Rand.Int() y otros métodos similares que devuelven o asignan valores son predecibles para un atacante que puede recopilar varios resultados de PRNG.

Ejemplo 1: Los valores que produce el generador de números pseudoaleatorios son predecibles en los dos primeros bloques porque ambos comienzan con el mismo valor de inicialización.


randomGen := rand.New(rand.NewSource(12345))
randomInt1 := randomGen.nextInt()

randomGen.Seed(12345)
randomInt2 := randomGen.nextInt()


En este ejemplo, los PRNG se inicializaron de forma idéntica, de modo que cada llamada a nextInt() después de la llamada que inicializó el generador de números pseudoaleatorios (randomGen.Seed(12345)), resulta en las mismas salidas y en el mismo orden.

Si un generador de números pseudoaleatorios (como Random) se inicializa con un valor específico (usando una función como Random.setSeed()), los valores devueltos por Random.nextInt() y métodos similares que devuelven o asignan valores son predecibles para un atacante que puede recopilar varios resultados de PRNG.

Ejemplo 1: Los valores que produce el objeto RandomrandomGen2 son predecibles desde el objeto RandomrandomGen1.


Random randomGen1 = new Random();
randomGen1.setSeed(12345);
int randomInt1 = randomGen1.nextInt();
byte[] bytes1 = new byte[4];
randomGen1.nextBytes(bytes1);

Random randomGen2 = new Random();
randomGen2.setSeed(12345);
int randomInt2 = randomGen2.nextInt();
byte[] bytes2 = new byte[4];
randomGen2.nextBytes(bytes2);


En este ejemplo, los generadores de números pseudoaleatorios: randomGen1 y randomGen2 se inicializaron de forma idéntica, por lo que randomInt1 == randomInt2 y los valores correspondientes de las matrices bytes1[] y bytes2[] son iguales.

Ejemplo 1: Los valores que produce el generador de números pseudoaleatorios son predecibles en los dos primeros bloques porque ambos comienzan con el mismo valor de inicialización.


...
import random
random.seed(123456)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)

random.seed(123456)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)
...


En este ejemplo los PRNG se inicializaron de manera idéntica, de modo que cada llamada a randint() después de la llamada que inicializó el generador de números pseudoaleatorios (random.seed(123456)) generará los mismos resultados en la misma salida en el mismo orden. Por ejemplo, la salida podría ser parecida a esta:


Random: 81
Random: 80
Random: 3
Random: 81
Random: 80
Random: 3


Estos resultados no son aleatorios en absoluto.

Abstract
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante.
Explanation
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento constante. Si un generador de números pseudoaleatorios (como Random) se inicializa con un valor específico (usando una función como Random.setSeed()), los valores devueltos por Random.nextInt() y métodos similares que devuelven o asignan valores son predecibles para un atacante que puede recopilar varios resultados de PRNG.

Ejemplo 1: Los valores que produce el objeto RandomrandomGen2 son predecibles desde el objeto RandomrandomGen1.


val randomGen1 = new Random()
randomGen1.setSeed(12345)
val randomInt1 = randomGen1.nextInt()
val bytes1 = new byte[4]
randomGen1.nextBytes(bytes1)

val randomGen2 = new Random()
randomGen2.setSeed(12345)
val randomInt2 = randomGen2.nextInt()
val bytes2 = new byte[4]
randomGen2.nextBytes(bytes2)


En este ejemplo, los generadores de números pseudoaleatorios: randomGen1 y randomGen2 se inicializaron de forma idéntica, por lo que randomInt1 == randomInt2 y los valores correspondientes de las matrices bytes1[] y bytes2[] son iguales.

Explanation
La clase CL_ABAP_RANDOM (o sus variantes) no deben inicializarse con un argumento contaminado. Al hacerlo, se permite que un usuario malintencionado controle el valor usado para inicializar el generador de números pseudoaleatorios y, por lo tanto, que pueda predecir la secuencia de valores producida por las llamadas a métodos como los siguientes: GET_NEXT, INT, FLOAT, PACKED.

Abstract
A las funciones que generan valores aleatorios o pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento contaminado.
Explanation
A las funciones que generan valores pseudoaleatorios, tales como ed25519.NewKeyFromSeed(), no se les debe llamar con un argumento contaminado. Si se hace, se permite que un usuario malintencionado controle el valor que se utiliza para inicializar el generador de números pseudoaleatorios, y así pueda predecir la secuencia de valores que producen las llamadas al generador de números pseudoaleatorios.

Si se hace, se permite que un usuario malintencionado controle el valor que se utiliza para inicializar el generador de números pseudoaleatorios, y así pueda predecir la secuencia de valores (normalmente enteros) que producen las llamadas a Random.nextInt(), Random.nextShort(), Random.nextLong(), o que devuelve Random.nextBoolean() o que se establecen en Random.nextBytes(byte[]).

Abstract
El generador de números aleatorios o pseudoaleatorios se basa en un origen de entropía poco seguro.
Explanation
La falta de un origen de entropía adecuado para el generador de números aleatorios o pseudoaleatorios puede dar lugar a la denegación del servicio o a la generación de secuencias de números predecibles. Si el generador de números aleatorios o pseudoaleatorios utiliza un origen de entropía que se agota, el programa puede interrumpirse o incluso bloquearse, dando lugar a una denegación del servicio. De forma alternativa, el generador de números aleatorios o pseudoaleatorios puede producir números predecibles. Un origen de números aleatorios o pseudoaleatorios poco seguro puede provocar vulnerabilidades tales como contraseñas temporales fáciles de adivinar, claves criptográficas predecibles, secuestro de sesiones y suplantación de identidad DNS.

Ejemplo 1: el código siguiente utiliza el reloj del sistema como origen de entropía:

...
srand (time(NULL));
r = (rand() % 6) + 1;
...


El reloj del sistema no es un buen origen de entropía porque genera valores predecibles. Lo mismo ocurre con otros orígenes de aleatoriedad no basados en hardware, como búferes de sistema/entrada/salida, direcciones o números de serie de usuario/sistema/hardware/red o la entrada del usuario.

Abstract
El uso de datos controlados por el usuario o que no son de confianza para definir la directiva de corrección de HTML podría permitir a un atacante evitar los requisitos de corrección y ejecutar ataques de Cross-Site Scripting (XSS).
Explanation
El término general "administración de entrada" describe funciones como la validación, la corrección, el filtrado y la codificación/decodificación de datos de entrada: Los ataques de scripts de sitios, la inyección de código SQL y las vulnerabilidades detectadas en el control de los procesos tienen todos su origen en la administración incorrecta o inexistente de entradas. La corrección de entradas, que implica la transformación de la entrada a una forma aceptable, normalmente se implementa además de la validación de entradas. La corrección de HTML hace referencia a la limpieza completa de la entrada del usuario para permitir únicamente etiquetas, atributos y elementos que se consideran seguros.
La implementación de una directiva de corrección de HTML completa es difícil, la clave de implementación correcta es comprender el contexto en el que se van a utilizar los datos. Cada contexto tiene sus propias vulnerabilidades y un tamaño no encaja con todos. Mientras que es útil utilizar un corrector de HTML (por ejemplo el corrector de HTML OWASP) para protegerse frente a vulnerabilidades de XSS en aplicaciones web, una implementación incorrecta puede conducir a una falsa sensación de seguridad.
Ejemplo 1: El siguiente código Java utiliza la variable de entrada controlada por el usuario elements en la creación de una directiva de corrección HTML:


...
String elements = prop.getProperty("AllowedElements");
...
public static final PolicyFactory POLICY_DEFINITION = new HtmlPolicyBuilder()
.allowElements(elements)
.toFactory();

....


Un usuario malintencionado puede provocar que la directiva de corrección HTML acepte elementos peligrosos como <script> proporcionándolos a elements.

Abstract
La aplicación implementa una interfaz SSL personalizada.
Explanation
El estándar SSL proporciona directrices sobre cómo realizar comprobaciones SSL en el cliente. Sin embargo, estas no forman parte del estándar. Por lo tanto, la implementación de la lógica de validación se deja en manos del desarrollador de la aplicación.

Las investigaciones han demostrado que la complejidad y la naturaleza abierta de la especificación del estándar SSL presentan varios escollos que complican la obtención de una implementación de SSL personalizada óptima. Un alto porcentaje de aplicaciones para Android que utilizan implementaciones de SSL personalizadas no logran proporcionar un canal de comunicaciones seguro, dejando a las aplicaciones vulnerables a ataques de tipo "man in the middle".

Abstract
El método no realiza las comprobaciones de SSL.
Explanation
Las llamadas a createSocket(), que adoptan InetAddress como parámetro de función, no realizan la comprobación de nombre de host.

Del mismo modo, las llamadas a getInsecure() devuelven una fábrica de sockets SSL con todas las comprobaciones de SSL deshabilitadas.

Estas dos situaciones provocan que la aplicación sea susceptible a un ataque de tipo "man in the middle".

Por ejemplo, la aplicación al intentar conectarse a https://safesecureserver.banking.com aceptaría sin problemas un certificado emitido a https://hackedserver.banking.com. La aplicación podría filtrar entonces información de usuario confidencial en una conexión SSL interrumpida en el servidor pirateado.

Abstract
La aplicación llama a un método que no es adecuado para la validación de la cadena de certificados.
Explanation
La aplicación llama a un método que devuelve la lista completa de certificados devueltos por el servidor sin eliminar los que no forman parte de una ruta de confianza válida entre el certificado de entidad final del servidor y un certificado de entidad de certificación en el que confía el sistema.

Si un atacante tuviera acceso a la clave privada de una entidad de certificación comprometida, podría interceptar la conexión SSL/TLS y modificar los certificados presentados por el servidor. En este caso, el atacante podría crear una ruta de confianza válida del certificado de entidad final del servidor a la entidad de certificación raíz comprometida para que el cliente confiase en el certificado y anexara el resto de los certificados originales presentados por el servidor.

Si el cliente usa la asignación de certificados, comprobará que el certificado "asignado" se encuentra entre los que presenta el servidor. Si el cliente usa un método que devuelve todos los certificados presentados por el servidor sin eliminar los que no forman parte de una ruta de confianza válida, un atacante con una clave privada comprometida válida podría presentar una ruta de confianza válida a su entidad de certificación comprometida y los certificados originales presentados por el servidor web. En ese caso, un atacante podría eludir la verificación de la asignación de certificados.

Abstract
Una conexión SSL/TLS se crea mediante las entidades de certificación del sistema predeterminadas que se han cargado con anterioridad, lo que puede permitir a los atacantes interceptar comunicaciones cifradas mediante ataques "man-in-the-middle" (MiTM) con certificados firmados por entidades de certificación raíz comprometidas.
Explanation
La infraestructura de clave pública (PKI) se basa en entidades de certificación de confianza; no obstante, el creciente número de entidades de certificación comprometidas implica que sus certificados raíz ya no son de confianza y que, por lo tanto, tampoco se puede confiar en los certificados que firman dichas entidades de certificación. Los atacantes en posesión de estos certificados comprometidos podrían interceptar todo el tráfico SSL/TLS que confíe en estas entidades de certificación.

Las firmas de las entidades de certificación son necesarias para las herramientas de comunicación de red generales, como los exploradores que se conectan a extremos de red arbitrarios y que no tienen conocimientos previos sobre las entidades de certificación que firman los certificados SSL/TLS de dichos extremos. Las aplicaciones móviles que se conectan a un número limitado de servidores back-end pueden beneficiarse del conocimiento de una lista de entidades de certificación de confianza que pueden usar dichos servidores para firmar sus certificados, así como "asignar" dichos certificados o claves públicas en las aplicaciones, de modo que la confianza se otorgue solo a los certificados que espera la aplicación.

Ejemplo 1: El siguiente ejemplo establece una conexión SSL/TLS mediante las entidades de certificación del sistema predeterminadas cargadas con anterioridad.

URL url = new URL("https://myserver.org");
URLConnection urlConnection = url.openConnection();
InputStream in = urlConnection.getInputStream();


Dado que no se ha cambiado el SSLSocketFactory subyacente usado por la URLConnection, se usará el valor predeterminado que confiará en todas las entidades de certificación presentes en el almacén de claves de Android predeterminado.

Abstract
Una conexión SSL/TLS se crea mediante las entidades de certificación del sistema predeterminadas que se han cargado con anterioridad, lo que puede permitir a los atacantes interceptar comunicaciones cifradas mediante ataques "man-in-the-middle" (MiTM) con certificados firmados por entidades de certificación raíz comprometidas.
Explanation
La infraestructura de clave pública (PKI) se basa en entidades de certificación de confianza; no obstante, el creciente número de entidades de certificación comprometidas implica que sus certificados raíz ya no son de confianza y que, por lo tanto, tampoco se puede confiar en los certificados que firman dichas entidades de certificación. Los atacantes en posesión de estos certificados comprometidos podrían interceptar todo el tráfico SSL/TLS que confíe en estas entidades de certificación.

Las firmas de las entidades de certificación son necesarias para las herramientas de comunicación de red generales, como los exploradores que se conectan a extremos de red arbitrarios y que no tienen conocimientos previos sobre las entidades de certificación que firman los certificados SSL/TLS de dichos extremos. Las aplicaciones móviles que se conectan a un número limitado de servidores back-end pueden beneficiarse del conocimiento de una lista de entidades de certificación de confianza que pueden usar dichos servidores para firmar sus certificados, así como "asignar" dichos certificados o claves públicas en las aplicaciones, de modo que la confianza se otorgue solo a los certificados que espera la aplicación.

Ejemplo 1: El siguiente ejemplo establece una conexión SSL/TLS mediante las entidades de certificación del sistema predeterminadas cargadas con anterioridad.

NSString* requestString = @"https://myserver.org";
NSURL* requestUrl = [NSURL URLWithString:requestString];
NSURLRequest* request = [NSURLRequest requestWithURL:requestUrl
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:10.0f];
NSURLConnection* connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];


Dado que no hay métodos NSURLConnectionDelegate definidos para gestionar la comprobación de certificados, se usarán los del sistema que confían en todas las entidades de certificación presentes en el almacén de claves predeterminado de iOS.

Abstract
La comprobación de la identidad del servidor se desactiva al establecer conexiones SSL.
Explanation
En algunas bibliotecas que utilizan conexiones SSL, el certificado de servidor no se comprueba de forma predeterminada. Esto equivale a confiar en todos los certificados. En otros casos, esto se puede deshabilitar de forma explícita, ya sea intencionalmente o no.

Ejemplo 1: Esta aplicación siempre comprueba que la cadena de certificados sea correcta, por lo que confía en todos los certificados.


...
private bool CertificateCheck(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
...
return true;
}
...
HttpWebRequest webRequest = (HttpWebRequest) WebRequest.Create("https://www.myTrustedSite.com");
webRequest.ServerCertificateValidationCallback = CertificateCheck;
WebResponse response = webRequest.GetResponse();
...


Al intentar conectarse a "https://www.myTrustedSite.com", esta aplicación aceptará sin objeciones un certificado emitido para "hackedserver.com". La aplicación podría filtrar entonces información de usuario confidencial en una conexión SSL interrumpida en el servidor pirateado.

Abstract
La comprobación de la identidad del servidor se desactiva al establecer conexiones SSL.
Explanation
En algunas bibliotecas que utilizan conexiones SSL, el certificado de servidor no se comprueba de forma predeterminada. Esto equivale a confiar en todos los certificados.

Ejemplo 1: esta aplicación no comprueba expresamente el certificado de servidor.


...
config := &tls.Config{
// Set InsecureSkipVerify to skip the default validation
InsecureSkipVerify: true,
...
}

conn, err := tls.Dial("tcp", "example.com:443", conf)
..


Al intentar establecer una conexión con example.com, esta aplicación aceptará sin objeciones cualquier certificado emitido por el servidor. Esta aplicación puede filtrar información de usuario confidencial en una conexión SSL interrumpida en el servidor pirateado.

Abstract
La comprobación de la identidad del servidor se desactiva al establecer conexiones SSL.
Explanation
En algunas bibliotecas que utilizan conexiones SSL, el certificado de servidor no se comprueba de forma predeterminada. Esto equivale a confiar en todos los certificados.

Ejemplo 1: este servidor intenta verificar las conexiones del cliente de forma incorrecta:


...
var options = {
key : fs.readFileSync('my-server-key.pem'),
cert : fs.readFileSync('server-cert.pem'),
requestCert: true,
...
}
https.createServer(options);
...


Cuando se crea el objeto https.Server, el parámetro requestCert se define como true, pero no se establece rejectUnauthorized, lo que establece false de forma predeterminada. Esto significa que, aunque el servidor se creó con la intención de verificar clientes en SSL, se seguirán aceptando conexiones incluso si el certificado no está autorizado con la lista de entidades de certificación proporcionadas.

Ejemplo 2: esta aplicación intenta conectarse con un servidor en SSL:


var tls = require('tls');
...
tls.connect({
host: 'https://www.hackersite.com',
port: '443',
...
rejectUnauthorized: false,
...
});


En este ejemplo, como rejectUnauthorized se estableció en el valor false, significa que se aceptarán certificados no autorizados y que de todas formas se creará una conexión segura con el servidor no identificado. La aplicación podría filtrar entonces información de usuario confidencial en una conexión SSL interrumpida en el servidor pirateado.

Abstract
La comprobación de la identidad del servidor se desactiva al establecer conexiones SSL.
Explanation
En algunas bibliotecas que utilizan conexiones SSL, el certificado de servidor no se comprueba de forma predeterminada (o se puede configurar de forma explícita para que así sea). Esto equivale a confiar en todos los certificados.

Ejemplo 1: este código configura NSURLConnectionDelegate para que acepte cualquier certificado HTTPS:


implementation NSURLRequest (IgnoreSSL)

+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
return YES;
}

@end


Al intentar conectarse a un servidor protegido con SSL usando la implementación de NSURLRequest del Example 1, no aparecerá ningún error o advertencia si el certificado del servidor que recibe la solicitud se ha firmado automáticamente (y, por lo tanto, no está verificado). Como resultado, la aplicación podría filtrar entonces información de usuario confidencial en una conexión SSL interrumpida.

Abstract
La comprobación de la identidad del servidor se desactiva al establecer conexiones SSL.
Explanation
En algunas bibliotecas que utilizan conexiones SSL, es posible deshabilitar la verificación del certificado de servidor. Esto equivale a confiar en todos los certificados.

Ejemplo 1: Esta aplicación no comprueba el certificado de servidor de forma predeterminada:


...
import ssl
ssl_sock = ssl.wrap_socket(s)
...


Al intentar la conexión con un host válido, esta aplicación aceptará sin objeciones un certificado emitido para "hackedserver.com". La aplicación podría filtrar entonces información de usuario confidencial en una conexión SSL interrumpida en el servidor pirateado.

Abstract
La comprobación de la identidad del servidor se desactiva al establecer conexiones SSL.
Explanation
En algunas bibliotecas que utilizan conexiones SSL, el certificado de servidor no se comprueba de forma predeterminada (o se puede configurar de forma explícita para que así sea). Esto equivale a confiar en todos los certificados.

Ejemplo 1: este código configura NSURLConnectionDelegate para que acepte cualquier certificado HTTPS:


class Delegate: NSObject, NSURLConnectionDelegate {

...

func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace?) -> Bool {
return protectionSpace?.authenticationMethod == NSURLAuthenticationMethodServerTrust
}

func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {
challenge.sender?.useCredential(NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!), forAuthenticationChallenge: challenge)
challenge.sender?.continueWithoutCredentialForAuthenticationChallenge(challenge)
}
}


Al intentar conectarse a un servidor protegido con SSL usando la implementación de NSURLConnectionDelegate del Example 1, no aparecerá ningún error o advertencia si el certificado del servidor que recibe la solicitud se ha firmado automáticamente (y, por lo tanto, no está verificado). Como resultado, la aplicación podría filtrar entonces información de usuario confidencial en una conexión SSL interrumpida.

Ejemplo 2: en una clase NSURLSession, la validación de la cadena SSL/TLS se controla a través del método de delegación de autenticación de la aplicación, pero en lugar de proporcionar al servidor las credenciales para autenticar al usuario (o aplicación), la aplicación comprueba las credenciales que proporciona el servidor durante el intercambio SSL/TLS e indica al sistema de carga de URL si debe aceptar o rechazar esas credenciales. El siguiente código muestra un NSURLSessionDelgate que devuelve la proposedCredential del desafío recibido como una credencial para la sesión, lo que en la práctica permite eludir la verificación del servidor:


class MySessionDelegate : NSObject, NSURLSessionDelegate {
...
func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {
...
completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential, challenge.proposedCredential)
...
}
...
}

Abstract
El programa utiliza el servicio de copia de seguridad de Android para guardar datos de aplicaciones persistentes en un almacenamiento en la nube remoto.
Explanation
El servicio de copia de seguridad de Android permite que la aplicación guarde los datos persistentes en un almacenamiento en la nube remoto para proporcionar un punto de restauración para los datos de la aplicación en el futuro.

Para configurar las aplicaciones para Android con este servicio de copia de seguridad, establezca el atributo allowBackup en true (el valor predeterminado) y defina el atributo backupAgent en la etiqueta <application>.

Sin embargo, Android no garantiza la seguridad de sus datos mientras utiliza la copia de seguridad, ya que el almacenamiento y el transporte en la nube varían de un dispositivo a otro.

Abstract
El programa escribe datos en el almacenamiento externo del dispositivo Android.
Explanation
Los datos guardados en el almacenamiento externo permiten un acceso de lectura general y solo los puede modificar el usuario cuando se habilite el almacenamiento masivo USB para transferir archivos en un equipo. Además, los archivos de la tarjeta de almacenamiento masivo permanecerán en esa ubicación, aunque se desinstale la aplicación que escribió estos. Estas limitaciones pueden poner en peligro la información confidencial escrita en el almacenamiento y permitir a los usuarios malintencionados introducir datos en el programa modificando un archivo externo que utilice.

Ejemplo 1: en el código siguiente, Environment.getExternalStorageDirectory() devuelve una referencia al almacenamiento externo del dispositivo Android.

 private void WriteToFile(String what_to_write) {
try{
File root = Environment.getExternalStorageDirectory();
if(root.canWrite()) {
File dir = new File(root + "write_to_the_SDcard");
File datafile = new File(dir, number + ".extension");
FileWriter datawriter = new FileWriter(datafile);
BufferedWriter out = new BufferedWriter(datawriter);
out.write(what_to_write);
out.close();
}
}
}

Abstract
La aplicación facilita el acceso a los datos a todas las aplicaciones del dispositivo Android.
Explanation
Los datos guardados en el almacenamiento interno de Android mediante MODE_WORLD_READBLE o MODE_WORLD_WRITEABLE están accesibles para todas las aplicaciones en el dispositivo. Esto no solo impide la protección frente al daño de datos, pero en el caso de información confidencial, infringe la privacidad del usuario y plantea riesgos de seguridad.

Abstract
El método identificado almacena los datos en las llaves con un nivel de accesibilidad que permite que se haga una copia de seguridad del elemento en iCloud y copias de seguridad de iTunes sin cifrar.
Explanation
Cuando se almacenan los datos en las llaves, es necesario configurar un nivel de accesibilidad que defina cuándo será posible acceder al elemento. Los niveles de accesibilidad posibles incluyen los siguientes:

-kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly:
No es posible acceder a los datos del elemento de las llaves después de un reinicio a menos que el usuario haya desbloqueado una vez el dispositivo.
Tras el primer desbloqueo, los datos permanecen accesibles hasta el próximo reinicio. Esta opción se recomienda para los elementos a los que deben tener acceso las aplicaciones en segundo plano. Los elementos con este atributo no migran a un dispositivo nuevo. Por lo tanto, al realizar una restauración con una copia de seguridad de otro dispositivo, estos elementos no estarán presentes.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleAlways:
Siempre se puede acceder a los datos del elemento de las llaves, independientemente de si el dispositivo está bloqueado.
No se recomienda usar esta opción con aplicaciones. Los elementos con este atributo migran a un dispositivo nuevo cuando se usan copias de seguridad cifradas.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly:
Solo se puede acceder a los datos de las llaves cuando el dispositivo está desbloqueado. Solo está disponible si se configura un código de acceso en el dispositivo.
Esta opción se recomienda para los elementos a los que solo es necesario tener acceso mientras la aplicación está en primer plano. Los elementos con este atributo nunca migran a un dispositivo nuevo. Tras restaurar una copia de seguridad en un dispositivo nuevo, no se encuentran estos elementos. Ningún elemento puede almacenarse en esta clase en los dispositivos sin un código de acceso. Si se deshabilita el código de acceso del dispositivo, se eliminan todos los elementos de esta clase.
Disponible en iOS 8.0 y posteriores.

-kSecAttrAccessibleAlwaysThisDeviceOnly:
Siempre se puede acceder a los datos del elemento de las llaves, independientemente de si el dispositivo está bloqueado.
No se recomienda usar esta opción con aplicaciones. Los elementos con este atributo no migran a un dispositivo nuevo. Por lo tanto, al realizar una restauración con una copia de seguridad de otro dispositivo, estos elementos no estarán presentes.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleWhenUnlocked:
Solo se puede acceder a los datos del elemento de las llaves mientras el dispositivo está desbloqueado por el usuario.
Esta opción se recomienda para los elementos a los que solo es necesario acceder mientras la aplicación está en primer plano. Los elementos con este atributo migran a un dispositivo nuevo cuando se usan copias de seguridad cifradas.
Este es el valor predeterminado para los elementos de las llaves que se agregan sin configurar de forma explícita una constante de accesibilidad.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleWhenUnlockedThisDeviceOnly:
Solo se puede acceder a los datos del elemento de las llaves mientras el dispositivo está desbloqueado por el usuario.
Esta opción se recomienda para los elementos a los que solo es necesario acceder mientras la aplicación está en primer plano. Los elementos con este atributo no migran a un dispositivo nuevo. Por lo tanto, al realizar una restauración con una copia de seguridad de otro dispositivo, estos elementos no estarán presentes.
Disponible en iOS 4.0 y posteriores.

A los niveles de accesibilidad que no contienen ThisDeviceOnly se les hará una copia de seguridad en iCloud y en iTunes incluso si se usan copias de seguridad sin cifrar que pueden restaurarse en cualquier dispositivo. Según el nivel de confidencialidad y privacidad de los datos almacenados, esto puede suponer un problema de privacidad.

Ejemplo 1: en el siguiente ejemplo, el elemento de las llaves está protegido en todo momento, excepto cuando el dispositivo está encendido y desbloqueado, pero se hará una copia de seguridad del elemento de las llaves en iCloud y en copias de seguridad de iTunes sin cifrar:


...
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
NSData *token = [@"secret" dataUsingEncoding:NSUTF8StringEncoding];

// Configure KeyChain Item
[dict setObject:(__bridge id)kSecClassGenericPassword forKey:(__bridge id) kSecClass];
[dict setObject:token forKey:(__bridge id)kSecValueData];
...
[dict setObject:(__bridge id)kSecAttrAccessibleWhenUnlocked forKey:(__bridge id) kSecAttrAccessible];

OSStatus error = SecItemAdd((__bridge CFDictionaryRef)dict, NULL);
...

Abstract
El método identificado almacena los datos en las llaves con un nivel de accesibilidad que permite que se haga una copia de seguridad del elemento en iCloud y copias de seguridad de iTunes sin cifrar.
Explanation
Cuando se almacenan los datos en las llaves, es necesario configurar un nivel de accesibilidad que defina cuándo será posible acceder al elemento. Los niveles de accesibilidad posibles incluyen los siguientes:

-kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly:
No es posible acceder a los datos del elemento de las llaves después de un reinicio a menos que el usuario haya desbloqueado una vez el dispositivo.
Tras el primer desbloqueo, los datos permanecen accesibles hasta el próximo reinicio. Esta opción se recomienda para los elementos a los que deben tener acceso las aplicaciones en segundo plano. Los elementos con este atributo no migran a un dispositivo nuevo. Por lo tanto, al realizar una restauración con una copia de seguridad de otro dispositivo, estos elementos no estarán presentes.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleAlways:
Siempre se puede acceder a los datos del elemento de las llaves, independientemente de si el dispositivo está bloqueado.
No se recomienda usar esta opción con aplicaciones. Los elementos con este atributo migran a un dispositivo nuevo cuando se usan copias de seguridad cifradas.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly:
Solo se puede acceder a los datos de las llaves cuando el dispositivo está desbloqueado. Solo está disponible si se configura un código de acceso en el dispositivo.
Esta opción se recomienda para los elementos a los que solo es necesario tener acceso mientras la aplicación está en primer plano. Los elementos con este atributo nunca migran a un dispositivo nuevo. Tras restaurar una copia de seguridad en un dispositivo nuevo, no se encuentran estos elementos. Ningún elemento puede almacenarse en esta clase en los dispositivos sin un código de acceso. Si se deshabilita el código de acceso del dispositivo, se eliminan todos los elementos de esta clase.
Disponible en iOS 8.0 y posteriores.

-kSecAttrAccessibleAlwaysThisDeviceOnly:
Siempre se puede acceder a los datos del elemento de las llaves, independientemente de si el dispositivo está bloqueado.
No se recomienda usar esta opción con aplicaciones. Los elementos con este atributo no migran a un dispositivo nuevo. Por lo tanto, al realizar una restauración con una copia de seguridad de otro dispositivo, estos elementos no estarán presentes.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleWhenUnlocked:
Solo se puede acceder a los datos del elemento de las llaves mientras el dispositivo está desbloqueado por el usuario.
Esta opción se recomienda para los elementos a los que solo es necesario acceder mientras la aplicación está en primer plano. Los elementos con este atributo migran a un dispositivo nuevo cuando se usan copias de seguridad cifradas.
Este es el valor predeterminado para los elementos de las llaves que se agregan sin configurar de forma explícita una constante de accesibilidad.
Disponible en iOS 4.0 y posteriores.

-kSecAttrAccessibleWhenUnlockedThisDeviceOnly:
Solo se puede acceder a los datos del elemento de las llaves mientras el dispositivo está desbloqueado por el usuario.
Esta opción se recomienda para los elementos a los que solo es necesario acceder mientras la aplicación está en primer plano. Los elementos con este atributo no migran a un dispositivo nuevo. Por lo tanto, al realizar una restauración con una copia de seguridad de otro dispositivo, estos elementos no estarán presentes.
Disponible en iOS 4.0 y posteriores.

A los niveles de accesibilidad que no contienen ThisDeviceOnly se les hará una copia de seguridad en iCloud y en iTunes incluso si se usan copias de seguridad sin cifrar que pueden restaurarse en cualquier dispositivo. Según el nivel de confidencialidad y privacidad de los datos almacenados, esto puede suponer un problema de privacidad.

Ejemplo 1: en el siguiente ejemplo, el elemento de las llaves está protegido en todo momento, excepto cuando el dispositivo está encendido y desbloqueado, pero se hará una copia de seguridad del elemento de las llaves en iCloud y en copias de seguridad de iTunes sin cifrar:


...
// Configure KeyChain Item
let token = "secret"
var query = [String : AnyObject]()
query[kSecClass as String] = kSecClassGenericPassword
query[kSecValueData as String] = token as AnyObject?
...
query[kSecAttrAccessible as String] = kSecAttrAccessibleWhenUnlocked

SecItemAdd(query as CFDictionary, nil)
...

Abstract
El método identificado configura la caché de respuestas HTTP(S) en una ubicación de almacenamiento compartido no seguro.
Explanation
Las respuestas de HTTP(S) pueden contener datos confidenciales, como cookies de sesión y tokens de API. El sistema de carga de URL guardará en la caché todas las respuestas de HTTP(S) por razones de rendimiento, y las almacenará sin cifrar en una ubicación de almacenamiento compartido no seguro.

Ejemplo 1: El código siguiente instala la caché de respuestas HTTP(S) en una ubicación de almacenamiento compartido no seguro:


protected void onCreate(Bundle savedInstanceState) {
...

try {
File httpCacheDir = new File(context.getExternalCacheDir(), "http");
long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
HttpResponseCache.install(httpCacheDir, httpCacheSize);
} catch (IOException e) {
Log.i(TAG, "HTTP response cache installation failed:" + e);
}
}

protected void onStop() {
...

HttpResponseCache cache = HttpResponseCache.getInstalled();
if (cache != null) {
cache.flush();
}
}

desc.dataflow.objc.insecure_storage_http_response_cache_leak
Abstract
El método identificado realiza una solicitud de URL sin configurar el sistema de carga de URL para evitar el almacenamiento en caché de las respuestas de HTTP(S).
Explanation
Las respuestas de HTTP(S) pueden contener datos confidenciales, como cookies de sesión y tokens de API. El sistema de carga de URL guardará en la caché todas las respuestas de HTTP(S) por razones de rendimiento, y las almacenará sin cifrar en los archivos {app ID}/Library/Caches/com.mycompany.myapp/Cache.db*.

desc.dataflow.swift.insecure_storage_http_response_cache_leak
Abstract
La aplicación intenta deshabilitar la caché de HTTP(S) configurando la capacidad de la caché del disco o la memoria en 0. Sin embargo, no hay ninguna garantía de que esta configuración se aplique.
Explanation
Las respuestas de HTTP(S) pueden contener datos confidenciales, como cookies de sesión y tokens de API. El sistema de carga de URL guardará en la caché todas las respuestas de HTTP(S) por razones de rendimiento, y las almacenará sin cifrar en los archivos {app ID}/Library/Caches/com.mycompany.myapp/Cache.db*.
Los desarrolladores pueden pensar que, al configurar las propiedades diskCapacity o memoryCapacity de la clase URLCache en 0, deshabilitan realmente el sistema de caché de respuesta de HTTP(S). Sin embargo, la documentación de NSURLCache indica que tanto la caché del disco como la de la memoria se truncarán en los tamaños configurados únicamente si al dispositivo le queda poca memoria o poco espacio en disco. Ambas configuraciones están diseñadas para que el sistema libere recursos del sistema y mejore el rendimiento, no como un control de seguridad.
