The Kerberos Key Distribution Center (KDC) in Microsoft Kerberos Key Distribution Center contains a privilege escalation flaw, in which a forged signature in a ticket is accepted, affecting Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, and Windows Server 2012 Gold and R2. An attacker with network access and valid low-privilege domain user credentials can forge a ticket signature to obtain domain administrator privileges, with no user interaction required.
Official description · NVDSource dataSource dataCopied from an authoritative feed: NVD, CVE.org, CISA KEV, FIRST EPSS or MITRE CTID mappings, or labelled by the annotators of a published dataset. Copied from NVD.
