Questions about CVE-2014-6324
What does this mean?
A flaw in the Kerberos KDC lets an unprivileged domain user account gain domain administrator privileges. With those privileges, an attacker could impersonate any user on the domain and compromise domain-joined systems.Source: learn.microsoft.com
Am I affected, and how do I check?
Domain controllers that are configured to act as a Kerberos Key Distribution Center (KDC) are primarily at risk. Check whether the domain controller is set up to run the KDC role.Source: learn.microsoft.com
What should I do about it?
Apply the fix listed for Windows Server 2012 R2 (3011780). No workaround is listed in the checked facts.Source: learn.microsoft.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-03-25, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
