Abstract
La presencia de cookies de sesión persistentes puede poner en peligro una cuenta.
Explanation
Una cookie de sesión persistente sigue siendo válida incluso después de cerrar el explorador y se suele utilizar como parte de una función "Recordar cuenta". Por lo tanto, una cookie de sesión persistente permite a los usuarios permanecer autenticados en una aplicación incluso después de cerrar el explorador, suponiendo que no hayan cerrado la sesión explícitamente. Esto significa que la siguiente persona que abra el explorador iniciará sesión automáticamente como el último usuario. A menos que se implemente la aplicación en un entorno controlado en el que los usuarios no tengan permiso para iniciar sesión desde equipos compartidos, los atacantes pueden poner en peligro las cuentas del usuario incluso después de cerrar el explorador.

Ejemplo 1: El siguiente código establece la cookie de sesión para que sea persistente.

server.servlet.session.cookie.persistent=true

desc.semantic.php.cookie_security_persistent_session_cookie
Abstract
La cookie de la sesión de aplicación se crea sin la marca Secure establecida en true.
Explanation
Los exploradores web modernos admiten una marca Secure para cada cookie. Si se define una marca, el explorador solo puede enviar la cookie a través de HTTPS. Enviar cookies a través de un canal no cifrado puede exponerlas a ataques de espionaje de red, por lo que las marcas seguras ayudan a mantener la confidencialidad del valor de una cookie. Esto es especialmente importante cuando la cookie contiene datos privados o porta un identificador de sesión.
Ejemplo 1: Una configuración que añade una cookie de sesión a la respuesta sin definir la marca Secure.

...
<configuration>
<system.web>
<authentication mode="Forms">
<forms requireSSL="false" loginUrl="login.aspx">
</forms>
</authentication>
</system.web>
</configuration>
...


Si su aplicación utiliza tanto HTTPS como HTTP, pero no define la marca Secure, las cookies enviadas durante una solicitud HTTPS también se enviarán en las solicitudes HTTP subsiguientes. El espionaje del tráfico de red a través de conexiones inalámbricas no cifradas es una tarea fácil para los atacantes, por lo que enviar cookies (sobre todo las que incluyen ID de sesión) a través de HTTP puede poner en peligro la aplicación.

Abstract
Es posible que la aplicación envíe la cookie de sesión a través de canales sin cifrar.
Explanation
Los exploradores web modernos admiten una marca Secure para cada cookie. Si se define una marca, el explorador solo puede enviar la cookie a través de HTTPS. Enviar cookies a través de un canal no cifrado puede exponerlas a ataques de espionaje de red, por lo que las marcas seguras ayudan a mantener la confidencialidad del valor de una cookie. Esto es especialmente importante cuando la cookie contiene datos privados o porta un identificador de sesión.

Ejemplo 1: La siguiente entrada de configuración desactiva el indicador Secure de las cookies de sesión.

server.servlet.session.cookie.secure=false


Si una aplicación utiliza tanto HTTPS como HTTP, pero no define la marca Secure, las cookies enviadas durante una solicitud HTTPS también se enviarán en las subsiguientes solicitudes HTTP. Los atacantes pueden secuestrar el tráfico de red no cifrado y poner en peligro la cookie, lo cual es especialmente fácil en el caso de las redes inalámbricas.

Abstract
El programa crea una cookie de sesión sin establecer la marca Secure en true.
Explanation
Los exploradores web modernos admiten una marca Secure en cada cookie. Si se incluye una marca, el explorador solo puede enviar la cookie a través de HTTPS. Enviar cookies a través de un canal no cifrado puede exponerlas a ataques de reconocimiento de red, por lo que las marcas seguras ayudan a mantener la confidencialidad del valor de una cookie. Esto es especialmente importante cuando la cookie contiene datos privados o porta un identificador de sesión.
Ejemplo 1: En código siguiente agrega una cookie a la respuesta sin establecer la marca Secure.

Si una aplicación utiliza tanto HTTPS como HTTP, pero no define la marca Secure, las cookies enviadas durante una solicitud HTTPS también se enviarán en las subsiguientes solicitudes HTTP. Los atacantes pueden secuestrar el tráfico de red no cifrado y poner en peligro la cookie, lo cual es especialmente fácil en el caso de las redes inalámbricas.

Abstract
El programa no establece explícitamente la propiedadSESSION_COOKIE_SECURE en True o la establece en False.
Explanation
Los exploradores web modernos admiten una marca Secure en cada cookie. Si se incluye una marca, el explorador solo puede enviar la cookie a través de HTTPS. Enviar cookies a través de un canal no cifrado puede exponerlas a ataques de reconocimiento de red, por lo que las marcas seguras ayudan a mantener la confidencialidad del valor de una cookie. Esto es especialmente importante cuando la cookie contiene datos privados o identificadores de sesión, o cuando porta un token de CSRF.
Ejemplo 1: la siguiente entrada de configuración no establece explícitamente el bit Secure para las cookies de sesión.

...
MIDDLEWARE = (
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'csp.middleware.CSPMiddleware',

Si una aplicación utiliza tanto HTTPS como HTTP, pero no define la marca Secure, las cookies enviadas durante una solicitud HTTPS también se enviarán en las subsiguientes solicitudes HTTP. Los atacantes pueden secuestrar el tráfico de red no cifrado y poner en peligro la cookie, lo cual es especialmente fácil en el caso de las redes inalámbricas.

Abstract
El programa no utiliza cookies para transmitir identificadores de sesión, lo cual deja la puerta abierta a posibles ataques de fijación de sesión y de secuestro de sesión.
Explanation
La mayoría de las aplicaciones web utiliza un identificador de sesión para identificar de forma única a los usuarios, el cual se almacena normalmente en una cookie y se transmite en transparente entre el servidor y el explorador web.


Las aplicaciones que no almacenan identificadores de sesión en las cookies a veces las transmiten como parámetros de solicitud HTTP o como parte de la URL. Aceptar identificadores de sesión especificados en direcciones URL hace que sea más fácil para los atacantes lanzar ataques de fijación de sesión.

Colocar identificadores en direcciones URL también puede aumentar las probabilidades de que los ataques de secuestro de sesión lanzados contra la aplicación tengan éxito. Los ataques de secuestro de sesión ocurren cuando un atacante asume el control de la sesión activa o del identificador de sesión de una víctima. Es práctica común de los servidores web, los servidores de aplicaciones y los proxies web almacenar direcciones URL solicitadas. Si se incluyen identificadores de sesión en las direcciones URL, también se registran. Aumentar el número de lugares en los que los identificadores de sesión se visualizan y se almacenan, aumenta el riesgo de ataque.

Abstract
El almacenamiento de un nombre de usuario de texto sin formato podría poner en peligro al sistema.
Explanation
Los problemas de administración de credenciales se producen cuando un nombre de usuario se acepta de un usuario o se almacena como texto sin formato en archivos de configuración o en la base de datos de una aplicación.
Ejemplo 1: El siguiente código lee un nombre de usuario de un formulario web y utiliza el nombre de usuario para conectarse a una base de datos.


<cfquery name = "GetCredentials" dataSource = "master">
SELECT Username, Password
FROM Credentials
WHERE DataSource="users"
</cfquery>
...
<cfquery name = "GetSSNs" dataSource = "users"
username = "#Username#" password = "#Password#">
SELECT SSN
FROM Users
</cfquery>
...


Este código se ejecutará correctamente, pero cualquier usuario que tenga acceso a la tabla master puede leer el valor de Username y Password. Un empleado malintencionado con acceso a esta información puede utilizarla para irrumpir en el sistema.

Abstract
Las credenciales de API codificadas de forma rígida pueden poner en riesgo la seguridad del sistema de una forma que no es fácil resolver.
Explanation
Nunca codifique credenciales de forma rígida, incluidos nombres de usuario, contraseñas, claves de API, secretos de API y tokens de API. Las credenciales codificadas de forma rígida no solo son visibles para todos los desarrolladores del proyecto, sino que también son extremadamente difíciles de actualizar. Una vez que el código está en producción, las credenciales no se pueden cambiar sin aplicar revisiones al software. Si las credenciales se ven comprometidas, la organización debe elegir entre seguridad y disponibilidad del sistema.

Abstract
Las credenciales de API codificadas de forma rígida pueden poner en riesgo la seguridad del sistema de una forma que no es fácil resolver.
Explanation
Nunca codifique credenciales de forma rígida, incluidos nombres de usuario, contraseñas, claves de API, secretos de API y tokens de API. Las credenciales codificadas de forma rígida no solo son visibles para todos los desarrolladores del proyecto, sino que también son extremadamente difíciles de actualizar. Una vez que el código está en producción, las credenciales no se pueden cambiar sin aplicar revisiones al software. Si las credenciales se ven comprometidas, la organización debe elegir entre seguridad y disponibilidad del sistema.

Abstract
Los nombres de usuario codificados pueden poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es una buena idea integrar un nombre de usuario en el código. Integrar un nombre de usuario en el código no solo permite a todos los desarrolladores del proyecto ver el nombre de usuario, sino que también hace que sea extremadamente difícil solucionar el problema. Una vez que el código está en producción, el nombre de usuario no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por el nombre de usuario se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.
Ejemplo 1: El siguiente código utiliza un nombre de usuario con codificación rígida para conectarse a una base de datos:


...
<cfquery name = "GetSSNs" dataSource = "users"
username = "scott" password = "tiger">
SELECT SSN
FROM Users
</cfquery>
...


Este código se ejecutará correctamente, pero cualquier usuario que tenga acceso al mismo tendrá acceso al nombre de usuario. Una vez que se haya distribuido el programa, no se podrá cambiar el usuario de base de datos "scott" con la contraseña "tiger", a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

Abstract
El programa puede permitir que un usuario no autorizado acceda a los datos desde otro cliente del sistema SAP.
Explanation
Los datos de aplicación en el sistema SAP están separados por cliente (separación por cliente) y todas las instrucciones Open SQL acceden/modifican de forma automática los datos que pertenecen al cliente que ha iniciado sesión (control de cliente). Se dispone así para que los datos que pertenecen a distintas unidades de negocio u organizaciones dentro de la empresa estén separados de forma lógica. Sin embargo, es posible eludir los mecanismos de separación por cliente y control de cliente desde un programa ABAP mediante el uso de:

1. Instrucciones SQL nativas, o
2. Instrucciones Open SQL con adición de CLIENT SPECIFIED, o
3. API ADBC (ABAP Database Connectivity), o
4. Otras API que acceden a datos específicos de cliente desde otros clientes

SAP no comprueba si el usuario tiene autorización para acceder a datos desde el cliente especificado. Esto supone un riesgo de seguridad, ya que un usuario no autorizado puede ver o modificar datos desde otro cliente.

Ejemplo 1: el siguiente código utiliza Open SQL para obtener detalles de empleados.


...
PARAMETERS: p_input TYPE sy-mandt.

SELECT *
FROM employee_records
CLIENT SPECIFIED
INTO TABLE tab_output
WHERE mandt = p_input.
...


En este caso, un usuario no autorizado que ejecute el código podrá ver los detalles de los empleados desde un cliente distinto al cliente SY-MANDT que ha iniciado sesión.

Abstract
Las sesiones basadas en cookies no se invalidan cuando un usuario cierra la sesión. Si un usuario malintencionado encontrara, robara o interceptara la cookie de un usuario, podría suplantar al usuario incluso si ese usuario ha cerrado la sesión.
Explanation
El almacenamiento de datos de sesión en cookies presenta varios problemas:

1. Las sesiones basadas en cookies no se invalidan cuando un usuario cierra la sesión. Si un usuario malintencionado encontrara, robara o interceptara la cookie de un usuario, podría suplantar al usuario incluso si ese usuario ha cerrado la sesión.

2. Las cookies de sesión se firman para evitar manipulaciones y garantizan la autenticidad de los datos, pero no evitarán ataques de reproducción.

3. Los datos de sesión se almacenarán a través de las herramientas de Django para firma criptográfica y la configuración SECRET_KEY. Si la configuración SECRET_KEY se filtra, un usuario malintencionado no solo puede falsificar los datos de sesión, sino que además, si la aplicación utiliza una subclase para serializar los datos de sesión en cookies, un usuario malintencionado podrá diseñar datos de subclase malintencionados que ejecutarán código arbitrario en el momento de deserialización.

4. Los datos de sesión se firman pero no se cifran. Esto significa que los usuarios malintencionados podrán leer los datos de sesión pero no modificarlos.

5. El proceso de serialización y el tamaño de cookie pueden suponer un problema de rendimiento en función de la carga del sitio.

Abstract
Si no se valida el encabezado de Host se puede permitir que un usuario malintencionado envíe un valor de Host falso que se puede utilizar para falsificación de solicitud de Cross-Site Scripting, ataques de envenenamiento de caché y envenenamiento de vínculos en correos electrónicos.
Explanation
La configuración de las aplicaciones de Django especifica "*" como una entrada en la configuración de ALLOWED_HOSTS. django.http.HttpRequest.get_host() utiliza esta configuración para validar el encabezado de Host. Un valor de "*" permitirá cualquier host en el encabezado de Host. Un atacante podría utilizar esto en ataques de envenenamiento de caché o para el envenenamiento de vínculos en correos electrónicos.

Ejemplo 1: Una aplicación ofrece una función para restablecer contraseñas donde los usuarios pueden enviar algún tipo de valor único para identificarse (por ej.: dirección de correo electrónico) y luego se enviará un correo electrónico para restablecer la contraseña con un vínculo a una página para establecer una contraseña nueva. El vínculo enviado al usuario se puede construir con el valor de Host para hacer referencia al sitio que facilita la función para restablecer la contraseña a fin de evitar direcciones URL con codificación rígida. Por ejemplo:


...
def reset_password(request):
url = "http://%s/new_password/?token=%s" % (request.get_host(), generate_token())
send_email(reset_link=url)
redirect("home")
...


Un atacante podría intentar restablecer la contraseña de una víctima enviando el correo electrónico de la víctima y un valor de encabezado de Host falso que señale un servidor que controla. La víctima recibirá un correo electrónico con un vínculo al sistema para restablecer contraseñas y si decide visitar el vínculo, estará visitando el sitio controlado por el usuario malintencionado que facilitará un formulario falso para recopilar las credenciales de la víctima.

Abstract
Las sesiones serializadas con subclases pueden provocar la ejecución de código remoto si los usuarios malintencionados pueden controlar los datos de sesión.
Explanation
Si se utilizan sesiones basadas en cookies y SECRET_KEY se filtra, un usuario malintencionado podrá almacenar datos arbitrarios en la cookie de sesión que se deserializará en el servidor, lo que provocará la ejecución de código arbitrario.

Si se utilizan sesiones basadas en cookies, tenga mucho cuidado y asegúrese de que la clave secreta siempre se mantenga completamente secreta para cualquier sistema que podría tener acceso remoto.

Ejemplo 1: El siguiente método de vista permite que un usuario malintencionado robe SECRET_KEY si se codifica en el archivo de configuración settings.py:


...
def some_view_method(request):
url = request.GET['url']
if "http://" in url:
content = urllib.urlopen(url)
return HttpResponse(content)
...


El método Example 1 comprueba que el parámetro url sea una dirección URL válida al comprobar que "http://" esté presente en la dirección URL. Un atacante malintencionado podría enviar la siguiente dirección URL para filtrar el archivo de configuración settings.py que puede contener SECRET_KEY:


file://proc/self/cwd/app/settings.py#http://


Nota: "/proc/self/cwd" en los sistemas UNIX señala el directorio de trabajo del proceso. Esto permite que los usuarios malintencionados hagan referencia a archivos sin conocer la ubicación exacta.

Abstract
El archivo carga un script a través de un canal no cifrado.
Explanation
La inclusión de contenido ejecutable de un sitio web a través de un canal no cifrado permite a un atacante lanzar un ataque "man-in-the-middle" (MiTM). Así, este podrá cargar su propio contenido, que se ejecutará como si formase parte del sitio web original.

Ejemplo 1: Considere la siguiente etiqueta script:

<script src="http://www.example.com/js/fancyWidget.js"></script>


Si un atacante está escuchando el tráfico de red entre el usuario y el servidor, puede imitar o manipular el contenido de www.example.com para cargar su propio JavaScript.

Abstract
Si se permite que la entrada de usuario modifique directamente los permisos de archivo, un atacante podría acceder a los recursos del sistema protegidos de otra forma.
Explanation
Se producen errores File Permission Manipulation cuando se cumplen algunas de las siguientes condiciones:

1. Un atacante puede especificar una ruta de acceso utilizada en una operación que modifica los permisos del sistema de archivos.

2. Un atacante puede especificar los permisos asignados por una operación en el sistema de archivos.

Ejemplo 1: El siguiente código utiliza la entrada de las variables de entorno del sistema para establecer los permisos de archivo. Si los atacantes pueden modificar las variables de entorno del sistema, pueden utilizar el programa para obtener acceso a los archivos que el programa ha manipulado. Si el programa también es vulnerable a Path Manipulation, un atacante puede utilizar esta vulnerabilidad para obtener acceso a archivos arbitrarios del sistema.

Abstract
Si se permite que la entrada de usuario modifique directamente los permisos de archivo, un atacante puede acceder a los recursos del sistema protegidos de otra forma.
Explanation
Se producen errores de manipulación de permisos de archivo cuando se cumplen algunas de las siguientes condiciones:

1. Un atacante puede especificar una ruta de acceso utilizada en una operación que modifica los permisos del sistema de archivos.

2. Un atacante puede especificar los permisos asignados por una operación en el sistema de archivos.

Ejemplo 1: El siguiente código se ha diseñado para establecer los permisos de archivo adecuados para los usuarios que cargan las páginas web a través de FTP. Utiliza la entrada de una solicitud HTTP para marcar un archivo como visible para los usuarios externos.


$rName = $_GET['publicReport'];
chmod("/home/". authenticateUser . "/public_html/" . rName,"0755");
...


Sin embargo, si un usuario malintencionado proporciona un valor malicioso para publicReport como, por ejemplo, "../../localuser/public_html/.htpasswd", la aplicación hará que el archivo especificado sea legible para el usuario malintencionado.

Ejemplo 2: el siguiente código utiliza la entrada desde un archivo de configuración para establecer la máscara de permisos predeterminada. Si los usuarios malintencionados pueden modificar el archivo de configuración, pueden utilizar el programa para obtener acceso a los archivos que el programa ha manipulado. Si el programa también es vulnerable a la manipulación de rutas de acceso, un usuario malintencionado puede utilizar esta vulnerabilidad para obtener acceso a archivos arbitrarios del sistema.

$mask = $CONFIG_TXT['perms'];
chmod($filename,$mask);

Abstract
El programa define una Política de apertura de orígenes cruzados (COOP) excesivamente permisiva.
Explanation
Se ha vuelto importante defender la privacidad de los datos de un documento web determinado debido a la existencia de explotaciones de canal lateral que resultan de vulnerabilidades como Spectre y Meltdown. La Política de apertura de orígenes cruzados (COOP) se creó para ayudar a prevenir la exposición de información confidencial debido a ataques de canal lateral. Específicamente, la COOP puede forzar el aislamiento del grupo del contexto de navegación de un documento con respecto a otros documentos externos, como ventanas emergentes.

Ejemplo 1: El siguiente código muestra una configuración COOP no segura de 'unsafe-none' en el marco Django. Esto podría permitir que un documento externo acceda a los datos privados del grupo del contexto de navegación de un documento fuente debido a un ataque de canal lateral.


SECURE_CROSS_ORIGIN_OPENER_POLICY = 'unsafe-none'

Abstract
Las restricciones de seguridad que especifican los verbos HTTP permiten a menudo más acceso del previsto.
Explanation
Los mecanismos de autenticación y autorización de una aplicación se pueden omitir con la manipulación del verbo HTTP cuando:
1) Se usa un control de seguridad que enumera los verbos HTTP.
2) El control de seguridad no bloquea los verbos que no figuran en la lista.
3) La aplicación actualiza su estado en función de las solicitudes GET u otros verbos HTTP arbitrarios.



La siguiente configuración es vulnerable a la manipulación de verbos HTTP:

<authorization>
<allow verbs="GET,POST" users="admin"/>
<deny verbs="GET,POST"users="*" />
</authorization>

Por defecto, el marco .NET admite todos los verbos HTTP, por lo que aunque esta configuración sí rechaza solicitudes GET y POST a todos los usuarios, no detiene solicitudes HEAD. Es posible que un atacante ejecute funciones administrativas sustituyendo las solicitudes GET o POST por solicitudes HEAD. En otras palabras, este código cumple las condiciones 1 y 2 anteriores. Todo lo que queda para que las solicitudes HEAD puedan ejecutar funciones administrativas es que la aplicación ejecute comandos en las solicitudes que contengan verbos distintos de POST.

En esencia, esta vulnerabilidad es el resultado de un intento de crear una lista de denegación, una directiva que especifica lo que los usuarios no pueden hacer. Las listas denegación rara vez logran el efecto deseado.

Abstract
Las restricciones de seguridad que especifican los verbos HTTP permiten a menudo más acceso del previsto.
Explanation
Los mecanismos de autenticación y autorización de una aplicación se pueden omitir con la manipulación del verbo HTTP cuando:
1) Se usa un control de seguridad que enumera los verbos HTTP.
2) El control de seguridad no bloquea los verbos que no figuran en la lista.
3) La aplicación actualiza su estado en función de las solicitudes GET u otros verbos HTTP arbitrarios.



La mayoría de las implementaciones de Java EE permiten métodos HTTP que no se enumeran explícitamente en la configuración. Por ejemplo, la siguiente restricción de seguridad se aplica al método HTTP GET pero no a otros verbos HTTP:


<security-constraint>
<display-name>Admin Constraint</display-name>
<web-resource-collection>
<web-resource-name>Admin Area</web-resource-name>
<url-pattern>/pages/index.jsp</url-pattern>
<url-pattern>/admin/*.do</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<description>only admin</description>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>


Dado que los verbos como HEAD no se definen explícitamente en una etiqueta <http-method> en esta configuración, es posible ejercer la funcionalidad administrativa sustituyendo las solicitudes GET o POST por solicitudes HEAD. Para que las solicitudes HEAD ejerzan funcionalidad administrativa, se debe cumplir la condición 3: la aplicación debe ejecutar comandos basados en verbos distintos de POST. Algunos servidores web/de aplicaciones aceptarán verbos HTTP no estándar arbitrarios y responderán como si se les hubiera dado una solicitud GET. Si ese es el caso, un atacante podría ver páginas administrativas usando un verbo arbitrario en una solicitud.

Por ejemplo, las solicitudes GET de cliente normalmente son así:

GET /admin/viewUsers.do HTTP/1.1
Host: www.example.com


En un ataque de manipulación de verbos HTTP, un atacante sustituiría GET por algo como FOO.

FOO /admin/viewUsers.do HTTP/1.1
Host: www.example.com


En esencia, esta vulnerabilidad es el resultado de un intento de crear una lista de denegación, una directiva que especifica lo que los usuarios no pueden hacer. Las listas denegación rara vez logran el efecto deseado.

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.


char* CreateReceiptURL() {
int num;
time_t t1;
char *URL = (char*) malloc(MAX_URL);
if (URL) {
(void) time(&t1);
srand48((long) t1); /* use time to set seed */
sprintf(URL, "%s%d%s", "http://test.com/", lrand48(), ".html");
}
return URL;
}


Este código utiliza la función lrand48() para generar identificadores "únicos" para las páginas de recibos que crea. Como lrand48() 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.

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.


String GenerateReceiptURL(String baseUrl) {
Random ranGen = new Random();
ranGen.setSeed((new Date()).getTime());
return (baseUrl + ranGen.nextInt(400000000) + ".html");
}


Este código utiliza la función Random.nextInt() para generar identificadores "únicos" para las páginas de recibos que crea. Como Random.nextInt() 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.


CREATE or REPLACE FUNCTION CREATE_RECEIPT_URL
RETURN VARCHAR2
AS
rnum VARCHAR2(48);
time TIMESTAMP;
url VARCHAR2(MAX_URL)
BEGIN
time := SYSTIMESTAMP;
DBMS_RANDOM.SEED(time);
rnum := DBMS_RANDOM.STRING('x', 48);
url := 'http://test.com/' || rnum || '.html';
RETURN url;
END


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 GenerateReceiptURL(baseUrl : String) : String {
val ranGen = new scala.util.Random()
ranGen.setSeed((new Date()).getTime())
return (baseUrl + ranGen.nextInt(400000000) + ".html")
}


Este código utiliza la función Random.nextInt() para generar identificadores "únicos" para las páginas de recibos que crea. Como Random.nextInt() 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


Estos resultados no son aleatorios en absoluto.

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.

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.


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.

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(Int)), 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 = Random(12345)
val randomInt1 = randomGen1.nextInt()
val byteArray1 = ByteArray(4)
randomGen1.nextBytes(byteArray1)

val randomGen2 = Random(12345)
val randomInt2 = randomGen2.nextInt()
val byteArray2 = ByteArray(4)
randomGen2.nextBytes(byteArray2)


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 byteArray1 y byteArray2 son iguales.

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 de entero constante.
Explanation
A las funciones que generan valores pseudoaleatorios, a las que se pasa un valor de inicialización, no se les debe llamar con un argumento de entero constante. Si se inicializa un generador de números pseudoaleatorios con un valor específico, los valores devueltos son predecibles.

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.

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
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 aleatorios o pseudoaleatorios (como rand()), a las que se pasa un valor de inicialización (como srand()), no se les debe llamar 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 (normalmente enteros) producida por las llamadas al generador de números pseudoaleatorios.

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
Las funciones que generan valores pseudoaleatorios (como random.randint()) no se deben llamar 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 (normalmente enteros) producida por las llamadas al generador de números pseudoaleatorios.

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 de entero contaminado.
Explanation
Random.setSeed() no debe llamarse con un argumento de entero 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 (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
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.
