CVE-2011-1894: The MHTML protocol handler in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1...

Security readout for executives and security teams

This vulnerability affects the Windows MHTML protocol handler used with Internet Explorer on older Windows versions. A malicious web page could trigger cross-site scripting through embedded content handling. The sources do not provide CVSS severity or evidence of active exploitation. Business urgency is mainly for legacy Windows and Internet Explorer environments. Exposure is most likely on legacy systems running affected Windows versions with Internet Explorer and the vulnerable MHTML handler. Modern environments without those platforms are unlikely to be directly exposed based on the supplied sources. Prioritize confirmation over emergency response unless legacy Internet Explorer systems remain in use. If present, treat remediation as important because web browsing can expose users to remote script abuse. Mitigation focus: Apply Microsoft security update MS11-037 where applicable.; Identify and retire unsupported affected Windows versions.; Restrict Internet Explorer use on legacy systems where replacement is pending..
