Microsoft Windows Video ActiveX Control RCE (CVE-2008-0015)

Historical catalog analysis: CISA added this entry on February 17, 2026. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2008-0015 is a remote code execution (RCE) vulnerability located within the Microsoft Windows Video ActiveX Control. The flaw allows an attacker to execute arbitrary code by inducing a user to view a specially crafted web page. If successful, the attacker gains the same privileges as the logged-on user.

Exposure and applicability

This vulnerability affects systems utilizing the Microsoft Windows Video ActiveX Control. Because this is a legacy component, exposure is primarily found in environments maintaining older software stacks or specific legacy browser configurations that still permit the execution of this control. The attack vector is network-based, requiring user interaction (visiting a malicious page) to trigger the execution.

Remediation priorities

Based on the reported vulnerability, our analysis suggests the following prioritization for infrastructure owners:

1. Inventory and Identification: Identify all assets where the Windows Video ActiveX Control is active and accessible via web browsers.
2. Vendor Mitigation: Apply official mitigations as specified in vendor instructions (e.g., MS09-032).
3. Product Decommissioning: If vendor mitigations are unavailable or cannot be applied to the specific environment, the product should be discontinued to eliminate the attack surface.
4. Cloud Service Alignment: For organizations utilizing cloud services, remediation efforts should align with BOD 22-01 guidance where applicable.

How to validate remediation

Verification must go beyond a simple version check or the presence of a patch installation record. To assure that exposure has been reduced, defenders should:

• Verify Control Status: Confirm whether the ActiveX control is disabled or removed from the browser environment across affected endpoints.
• Configuration Audit: Validate that browser security settings prevent the execution of the specific vulnerable control in untrusted zones.
• Functional Testing: Ensure that the removal or mitigation of the control does not break critical legacy business functions, while confirming the component no longer initializes when presented with a trigger page.

Limits and open questions

There is residual risk if the ActiveX control remains enabled for compatibility reasons despite patching, as some legacy components may exhibit unpredictable behavior in modern environments. It remains unknown whether this vulnerability is currently being leveraged in active ransomware campaigns. Additionally, while CISA has established a remediation deadline of March 10, 2026, for federal agencies, this date serves as a benchmark rather than a mandatory requirement for non-federal entities.
