Description
The 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
target server supporting better encryption (eg aes256-cts-hmac-sha1-96).
A remote attacker can perform an offline attack against the ticket
encrypted with rc4-hmac and login as a privileged user.
