Privilege escalation through undisclosed Kerberos flaw
Published Sep 10, 2024 · Updated Aug 10, 2026
Weak authentication in Microsoft Windows Kerberos allows remote authenticated users with high privileges to elevate privileges over a network. Microsoft has not disclosed the Kerberos locus or the authentication operation that mishandles untrusted input. The attacker must already hold high privileges and network reachability; the resulting privilege boundary and elevated identity remain unspecified.
