Name of the Vulnerable Software and Affected Versions
openssl encrypt versions prior to 1.4.9
Description
The software stores an unkeyed SHA-256 hash of the plaintext within the cleartext file header metadata. This allows attackers to read the hash without requiring a password, enabling them to confirm guessed plaintexts offline or identify identical plaintexts across different encrypted files.
Recommendations
Update to version 1.4.9 or later.
