Descriptions
Sophos SafeGuard Enterprise before 8.00.5, SafeGuard Easy before 7.00.3, and SafeGuard LAN Crypt before 3.95.2 are vulnerable to Local Privilege Escalation via IOCTL 0x80206024. By crafting an input buffer we can control the execution path to the point where a global variable will be written to a user controlled address. We can take advantage of this condition to zero-out the pointer to the security descriptor in the object header of a privileged process or modify the security descriptor itself and run code in the context of a process running as SYSTEM.
Sophos SafeGuard Enterprise en versiones anteriores a la 8.00.5, SafeGuard Easy en versiones anteriores a la 7.00.3, y SafeGuard LAN Crypt en versiones anteriores a la 3.95.2 son vulnerables a una escalada de privilegios local mediante IOCTL 0x80206024. Manipulando un búfer de entrada, es posible controlar la ruta de ejecución al puntero, en el que se escribirá una variable global en una dirección controlada por el usuario. Se puede aprovechar esta situación para eliminar el puntero al descriptor de seguridad en la cabecera del objeto de un proceso privilegiado o modificar el descriptor de seguridad en sí para ejecutar código en el contexto de un proceso que se está ejecutando como SYSTEM.
