Kerberos is vulnerable to privilege escalation. The the MIT Kerberos administration server (kadmind) incorrectly accepted certain authentication requests for two-component server principal names. A remote attacker able to acquire a key with a particularly named principal (such as “kad/x”) could use this flaw to impersonate any user to kadmind, and perform administrative actions as that user.
