The Microsoft Office Web Components Spreadsheet ActiveX control (aka OWC10 or OWC11), as distributed in Office XP SP3 and Office 2003 SP3, Office XP Web Components SP3, Office 2003 Web Components SP3, Office 2003 Web Components SP1 for the 2007 Microsoft Office System, Internet Security and Acceleration (ISA) Server 2004 SP3 and 2006 Gold and SP1, and Office Small Business Accounting 2006, when used in Internet Explorer, allows remote attackers to execute arbitrary code via a crafted call to the msDataSourceObject method, as exploited in the wild in July and August 2009, aka "Office Web Components HTML Script Vulnerability."

Security readout for executives and security teams

CVE-2009-1136 is a remote code execution flaw in Microsoft Office Web Components used through Internet Explorer. A malicious web page could abuse the Spreadsheet ActiveX control on affected legacy Microsoft products. The source bundle reports exploitation in the wild in July and August 2009, but does not show current KEV listing. Exposure is most likely in legacy Windows environments that still run Internet Explorer with ActiveX enabled and have affected Office Web Components or bundled Microsoft products installed. Modern environments without these legacy components are less likely exposed, but old line-of-business apps can keep OWC installed. Treat this as high priority only where legacy Microsoft Office Web Components remain deployed. The business risk is remote code execution through browser-based content, amplified by historical exploitation. If legacy IE and ActiveX are absent, priority drops to confirming non-exposure. Mitigation focus: Apply Microsoft MS09-043 guidance for affected systems.; Remove or retire affected Office Web Components where no longer needed.; Restrict Internet Explorer ActiveX execution for untrusted content..
