This signature detects attempts to use unsafe ActiveX controls in Microsoft Office Web Components. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.
Microsoft Office Web Components (OWC) are a collection of ActiveX objects which provide limited Office functionality to web pages. OWC is installed by default with both Office 2000 and Office XP. A vulnerability has been reported within some versions of the OWC Spreadsheet component. It is possible for a web page using this component to read the content of any known local file.
