Summary

The QNAP TS-239 Pro and TS-639 Pro devices running specific firmware versions contain a significant vulnerability that allows local users to bypass the passphrase requirement for decrypting the hard drive. This occurs through the creation of an undocumented recovery key stored in the ENCK variable within the device's flash memory. By accessing this variable, users can deobfuscate the key and utilize the cryptsetup luksOpen command to gain unauthorized access to the encrypted data.
