Security readout for executives and security teams

CVE-2011-1877 is a Windows kernel privilege-escalation flaw. An attacker who can run code locally could potentially gain higher privileges on affected Windows Vista, Server 2008, and Windows 7 systems. This is mainly a legacy Windows exposure issue today. Exposure is most likely on unpatched legacy Windows Vista, Windows Server 2008, Windows Server 2008 R2, and Windows 7 systems. Modern unsupported or isolated inventory gaps may hide affected hosts. Treat this as high priority where affected legacy Windows remains in production. It is not described as remotely exploitable, but kernel privilege escalation can materially worsen any endpoint compromise. Mitigation focus: Review Microsoft MS11-054 for the official update and affected platform details.; Patch affected Windows Vista, Server 2008, Server 2008 R2, and Windows 7 systems.; Retire or isolate unsupported legacy Windows systems that cannot receive vendor updates..
