Microsoft Access Snapshot Viewer ActiveX
Snapshot Viewer for Microsoft Access, included by default with Microsoft Office Access 2000, 2002, 2003.
The Microsoft Access Snapshot Viewer ActiveX control is a component that enables a user to view an Access report snapshot without having the standard or run-time versions of Microsoft Office Access. A vulnerability exists within the ActiveX control that allows an attacked to execute arbitrary code on a victims machine if they visit a malicious website that call the vulnerable ActiveX control in a malicious manner.
Exploit code for this has not been publicly released in a public forum.
Arbitrary code execution under the context of the logged in user
ActiveX remote code execution vulnerabilities have very high impacts since the source of the malicious payload can be any site on the Internet. An even more critical problem is generated when clients are administrators on their local hosts, which would run the malicious payload with Administrator credentials.
The best form of mitigation is available by kill-bitting the CLSIDs for the ActiveX Control (F0E42D50-368C-11D0-AD81-00A0C90DC8D9, F0E42D60-368C-11D0-AD81-00A0C90DC8D9, F2175210-368C-11D0-AD81-00A0C90DC8D9) following the directions of KB240797. This will disable calls to these ActiveX controls from web pages, thereby mitigating these specific vulnerabilities.
