    Summary: WWBN AVideo Weak PRNG Password Generation via External Login

    Details: WWBN AVideo generates passwords for external-login accounts using rand() instead of a cryptographic generator, producing only 31-bit integers. Attackers with access to password hashes can recover plaintext passwords in minutes through offline brute-force attacks due to unsalted MD5-based hashing.
