Descriptions

The QNAP TS-239 Pro and TS-639 Pro with firmware 2.1.7 0613, 3.1.0 0627, and 3.1.1 0815 create an undocumented recovery key and store it in the ENCK variable in flash memory, which allows local users to bypass the passphrase requirement and decrypt the hard drive by reading this variable, deobfuscating the key, and running a cryptsetup luksOpen command.

QNAP TS-239 Pro y TS-639 Pro con firmware v2.1.7 0613, v3.1.0 0627, y v3.1.1 0815 crea una clave de recuperación no documentada y la almacena en la variable ENCK en memoria flash, permitiendo a usuarios locales saltar el requisito de contraseña y desencriptar el disco duro mediante la lectura de esta variable, desofuscando la clave, y ejecutando un comando cryptsetup luksOpen.

QNAP Systems versions TS-239 Pro and TS-639 Pro suffer from a hard disk encryption bypass vulnerability.
