Descriptions

The CryptProtectMemory function in cng.sys (aka the Cryptography Next Generation driver) in the kernel-mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1, when the CRYPTPROTECTMEMORY_SAME_LOGON option is used, does not check an impersonation token's level, which allows local users to bypass intended decryption restrictions by leveraging a service that (1) has a named-pipe planting vulnerability or (2) uses world-readable shared memory for encrypted data, aka "CNG Security Feature Bypass Vulnerability" or MSRC ID 20707.

La función CryptProtectMemory en cng.sys (también conocido como el controlador Cryptography Next Generation) en los controladores de modo de kernel en Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold y R2, y Windows RT Gold y 8.1, cuando la opción CRYPTPROTECTMEMORY_SAME_LOGON está utilizada, no comprueba el nivel de un token de suplantación, lo que permite a usuarios locales evadir las restricciones del descifrado mediante el aprovechamiento de un servicio que (1) tiene una vulnerabilidad de inyección mediante el canal anteriormente nombrado (named-pipe planting) o (2) utiliza memoria compartida de lectura universal para datos cifrados, también conocido como 'vulnerabilidad de la evasión de la característica de seguridad CNG' o MSRC ID 20707.
