Reino: API Abuse

Un API es un contrato entre un autor de llamada y un receptor de llamada. Las formas de abuso de API más comunes los produce el autor de llamada cuando no consigue atender su fin de este contrato. Por ejemplo, si un programa no consigue llamar chdir() después de llamar chroot(), se viola el contrato que especifica cómo cambiar el directorio de origen activo de una forma segura. Otro buen ejemplo de un abuso de manual es esperar que el receptor devuelva una información de DNS de confianza al autor de llamada. En este caso, el autor de llamada abusa el API del receptor haciendo determinadas suposiciones sobre su comportamiento (que el valor de retorno se puede usar con fines de autenticación). También se puede violar el contrato entre el autor de llamada y el receptor desde el otro lado. Por ejemplo, si un codificador envía SecureRandom y devuelve un valor no aleatorio, se viola el contrato.

Often Misused: Privilege Management

Abstract
El incumplimiento del principio de menor privilegio amplifica el riesgo que plantean otras vulnerabilidades.
Explanation
Los programas que se ejecutan con privilegios root han provocado innumerables desastres de seguridad de Unix. Es imprescindible que revise atentamente los programas con privilegios en relación con todos los tipos de problemas de seguridad, pero es igual de importante restablecer los programas con privilegios a un estado sin ellos tan rápido como sea posible a fin de limitar la cantidad de daños que puede provocar una vulnerabilidad que se pasó por alto.


Las funciones de administración de privilegios se pueden comportar de forma algo menos obvias, y presentan diferentes peculiaridades en las distintas plataformas. Estas incoherencias son especialmente pronunciadas al pasar de un usuario que no es root a otro.

Los controladores de señales y los procesos generados se ejecutan en el privilegio del proceso propietario, por lo que si el proceso se está ejecutando como root cuando se desencadena una señal o se ejecuta un subproceso, el controlador de señales funcionará con privilegios raíz. Es posible que un usuario malintencionado aproveche estos privilegios elevados para realizar aún más daño.

Abstract
El incumplimiento del principio de privilegios mínimos amplía el riesgo que suponen otras vulnerabilidades.
Explanation
Los programas que funcionan con privilegios de root han causado innumerables desastres de seguridad Unix. Es absolutamente necesario que revise cuidadosamente los programas privilegiados para descubrir cualquier tipo de problema de seguridad, pero es igualmente importante que los programas privilegiados vuelvan a un estado no privilegiado tan pronto como sea posible para limitar el daño total que una vulnerabilidad no detectada pueda causar.


Las funciones de gestión de privilegios pueden realizarse de formas menos que obvias, y tienen diferentes particularidades en las diferentes plataformas. Estas inconsistencias son especialmente evidentes si se cambia de un usuario no root a otro.

Los tratamientos de señales y los procesos generados funcionan sobre el privilegio del proceso de apropiación, de modo que si un proceso está funcionando como root cuando una señal salta o se ejecuta un subproceso, el tratamiento de señales o el subproceso operará con privilegios de origen. Un atacante puede ser capaz de aprovechar estos privilegios avanzados para hacer más daño.
