Reino: Security Features
La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.
Access Control: Database
Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:
1. Los datos entran en un programa desde un origen que no es de confianza.
2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el código siguiente utiliza una instrucción que se basa en un número entero y, por tanto, no es vulnerable a las vulnerabilidades de SQL Injection, para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.
El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:
1. Los datos entran en un programa desde un origen que no es de confianza.
2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el siguiente código utiliza una instrucción parametrizada, que aplica caracteres de escape a metacaracteres e impide la inclusión de vulnerabilidades de SQL Injection, para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.
El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal controlada por el atacante, se puede otorgar al atacante acceso a los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:
1. Los datos entran en un programa desde un origen que no es de confianza.
2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: El siguiente código utiliza una instrucción parametrizada, la cual establece secuencias de escape para los metacaracteres e impide las vulnerabilidades SQL Injection, para crear y ejecutar una consulta SQL que busque una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.

Algunos piensan que en el mundo de las plataformas móviles, las vulnerabilidades de las aplicaciones web clásicas, como los errores de control de acceso a bases de datos, no tienen ningún sentido: ¿por qué se atacaría un usuario a sí mismo? Sin embargo, tenga en cuenta que la esencia de las plataformas móviles consiste en aplicaciones que se descargan desde varias fuentes y se ejecutan junto con otras en el mismo dispositivo. La probabilidad de ejecutar un malware junto a una aplicación de banca es bastante alta, de modo que se necesita expandir la superficie expuesta a ataques de las aplicaciones móviles para que incluyan las comunicaciones entre procesos.

Abstract
Sin el control de acceso adecuado, el método identificado puede ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, lo que le permite tener acceso a los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:
1.Los datos entran en un programa desde un origen que no es de confianza.
2.Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el siguiente código utiliza una instrucción parametrizada, que aplica caracteres de escape a metacaracteres e impide la inclusión de vulnerabilidades de SQL Injection para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.
El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:
1. Los datos entran en un programa desde un origen que no es de confianza.
2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el siguiente código utiliza una instrucción parametrizada, que aplica caracteres de escape a metacaracteres e impide la inclusión de vulnerabilidades de SQL Injection, para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.
El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de

El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de

Abstract
Sin el control de acceso adecuado, el método identificado puede ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, lo que le permite tener acceso a los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:
1.Los datos entran en un programa desde un origen que no es de confianza.
2.Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el siguiente código utiliza una instrucción parametrizada, que aplica caracteres de escape a metacaracteres e impide la inclusión de vulnerabilidades de SQL Injection para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.
El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de

Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.References
