Titel:	OpenCast < 8.1.0 Password Hashing Vulnerability
Zusammenfassung:	OpenCast is prone to an insecure password hashing vulnerability.
Beschreibung:	Summary: OpenCast is prone to an insecure password hashing vulnerability. Vulnerability Insight: User passwords are stored in the database using the rather outdated and cryptographically insecure MD5 hash algorithm. Furthermore, the hashes are salted using the username instead of a random salt, causing hashes for users with the same username and password to collide which is problematic especially for popular users like the default admin user. This essentially means that for an attacker, it might be feasible to reconstruct a user's password given access to these hashes. Note that attackers needing access to the hashes means that they must gain access to the database in which these are stored first to be able to start cracking the passwords. Affected Software/OS: OpenCast versions prior to 8.1.0. Solution: Update to version 8.1.0 or later. Note, that old hashes remain MD5 until the password is updated. CVSS Score: 5.5 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:P/A:N
