This signature detects attempts to exploit a known vulnerability against Kerberos Administration Server (kadmind) version 5-1.6.1 and earlier. A successful attack can lead to arbitrary code execution.
MIT Kerberos 5 Administration Daemon ('kadmind') is prone to a remote code-execution vulnerability. An attacker can exploit this issue to execute arbitrary code with superuser privileges, completely compromising affected computers. Failed exploit attempts will likely result in denial-of-service conditions. All 'kadmind' servers run on the master Kerberos server. Since the master server holds the KDC principal and policy database, an attack may not only compromise the affected computer, but could also compromise multiple hosts that use the server for authentication. This issue also affects third-party applications using the affected RPC library. Versions prior to 'kadmind' krb5-1.6.1 are vulnerable.
