Security readout for executives and security teams
CVE-2011-0671 is a Windows kernel privilege escalation flaw. A person or malware already able to run a crafted local application on an affected Windows host could gain higher privileges. This is not described as remote initial access, but it can turn a foothold into full system compromise. Exposure is most likely on systems running the Windows versions named in the CVE: Windows XP SP2/SP3, Server 2003 SP2, Vista SP1/SP2, Server 2008 variants, and Windows 7 Gold/SP1. Treat this as high priority for any remaining affected Windows assets. It is most dangerous after an attacker has local code execution, because it can remove privilege boundaries and enable deeper compromise. Mitigation focus: Apply Microsoft’s MS11-034 security update where applicable.; Inventory endpoints for the affected Windows versions named by Microsoft.; Prioritize remediation on shared workstations, servers, and systems allowing untrusted local code..
