Name of the Vulnerable Software and Affected Versions
openssl-encrypt versions prior to 1.4.9
Description
The portable USB drive feature contains two weaknesses when the removable drive is treated as untrusted. First, the
verify integrity file() function in USBDriveCreator only validates files listed in the manifest, allowing additional files, such as root-level autorun payloads, to remain undetected while integrity verification still passes. Second, a globally constant, source-embedded KDF salt LEGACY FIXED SALT is used to derive the drive encryption key for any drive lacking a per-drive salt file. This removes precomputation resistance and enables offline rainbow-table attacks, which use precomputed hashes to quickly recover passwords.Recommendations
Update openssl-encrypt to version 1.4.9 or later.
