A critical vulnerability in the Microsoft Windows Kerberos Key Distribution Center (KDC) has been released. All server versions of Windows are affected [1].
An attacker that successfully exploited this vulnerability could impersonate any user on the domain, including domain administrators, and join any group.
Airlock WAF and especially the Airlock Kerberos Agent [3] are not affected by the vulnerability.
If you are using the Microsoft Kerberos KDC we recommend to install the security update referenced in the Microsoft Security Bulletin MS14-068 [2] on all affected systems.
