CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication.
The
vulnerability exists due to an error that allows an attacker to force
the server so issue an rc4-hmac ticket encrypted tickets despite the

A remote attacker can perform an offline attack against the ticket
encrypted with rc4-hmac and login as a privileged user.
