Version Summary:Microsoft has released an additional security bulletin and software updates to address the Microsoft Windows video msvidctl ActiveX control code execution vulnerability.
 
 
Description

Microsoft Windows contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.

The vulnerability is due to?a stack overwrite error?in the Microsoft Video ActiveX control.? An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to view a malicious website.? If successful, the attacker could execute arbitrary code with the privileges of the user, possibly resulting in complete system compromise.

Exploit code has been detected in the wild and is being used as part of ongoing attacks.

Microsoft confirmed this vulnerability in a security bulletin and released software updates.

IntelliShield Analysis

Attackers cannot directly exploit this vulnerability and instead must rely on user interaction to accomplish an exploit.? An attacker may attempt to convince a user to visit a malicious website by sending links to the user in targeted e-mail messages.? Attackers may also embed exploits in public sites as the result of site server compromises or functionality that allows the upload of untrusted third-party content.? In this case, the attacker would?rely on users to visit those sites on their own.

If an exploit is successful, the attacker could execute arbitrary code with the privileges of the user, which may allow the attacker to completely compromise the system.

Ongoing attacks have been detected.? Attackers have used exploits to install malicious software on vulnerable systems.

The update available from Microsoft corrects this vulnerability by preventing the vulnerable control from being instantiated within browser applications.

Event data from Cisco Remote Management Services has detected intrusion prevention system signature activity related to this vulnerability. The data, which was captured on July 21, 2009, could indicate that exploitation of this vulnerability is taking place in the wild.

The Cisco Applied Intelligence team has re-released the following companion document to guide administrators in identifying and mitigating attempts to exploit this vulnerability prior to applying updated software: Cisco Applied Mitigation Bulletin: Identifying and Mitigating the Microsoft Windows Video msvidctl ActiveX Control Code Execution Vulnerability

 
Vendor Announcements

Microsoft has released security bulletins at the following links: MS09-032 and MS09-037

Microsoft released a security advisory at the following link: Microsoft Security Advisory 972890 

US-CERT has released a vulnerability note at the following link: VU#180513 

 
Impact

An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code with the privileges of the user, possibly allowing the attacker to gain complete control over the system if the user holds elevated privileges.

 
Technical Information

The vulnerability is due to a stack overwrite error in an ActiveX control in the Microsoft DirectShow msvidctl.dll component.  The Microsoft Video ActiveX control (BDATuner.MPEG2TuneRequest.1) may fail to properly sanitize user-supplied input. The vulnerability is in the Load method of the ATL template interface IPersistStreamInit when it handles crafted input that is supplied to the data property. 

An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to view a malicious website.  Successful exploitation could allow the attacker to execute arbitrary code with the privileges of the user, which may result in complete system compromise.

 
Safeguards

Administrators are advised to apply the appropriate updates.

Administrators may consider configuring Internet Explorer to prompt users before running Active Scripting or ActiveX controls by setting the Internet and Local Intranet security zone settings to High.  Alternately, administrators could disable Active Scripting and ActiveX controls in these security zones.

Users are advised not to visit websites or follow links that have suspicious characteristics or cannot be verified as safe.

Users are advised to run applications with the least privileges necessary.

Cisco Security Intelligence Operations has tested Cisco Security Agent to verify that it prevents the malicious actions initiated by active exploitation of this vulnerability.  As a result, system compromise is mitigated.

 
Patches/Software

Microsoft customers can obtain updates directly by using the links in the security bulletin.  These updates are also distributed by Windows automatic update features and available on the Windows Update website.  Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
