# CVE-2008-0015:  Microsoft Windows Video ActiveX Control Remote Code Execution Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Microsoft Windows. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-02-17, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-03-10 ; treat that as the outer limit, not the target.
- EPSS 76.6% , percentile 99.5: FIRST’s model estimates a 76.6% chance of exploitation activity in the next 30 days, higher than 99.5% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.

## What it is

Stack-based buffer overflow in the CComVariant::ReadFromStream function in the Active Template Library (ATL), as used in the MPEG2TuneRequest ActiveX control in msvidctl.dll in DirectShow, in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 allows remote attackers to execute arbitrary code via a crafted web page, as exploited in the wild in July 2009, aka "Microsoft Video ActiveX Control Vulnerability."

## Affected products (CVE record)

- n/a n/a: see advisory

## Severity

- CISA-ADP CVSS 3.1: 8.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H`

## Exploitation

- CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 76.58% probability of exploitation activity in the next 30 days; percentile 99.5.
