Detailed vulnerability description

The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to use of a broken or risky cryptographic algorithm in the DHCAST128 UAM when performing password authentication. A remote attacker can observe the authentication exchange to disclose sensitive information.

A 16-byte hardcoded Diffie-Hellman prime makes passive password recovery trivially solvable.
