CISA KEV Advisory

Microsoft Silverlight Double Dereference Vulnerability

Microsoft Silverlight does not properly validate pointers during HTML object rendering, which allows remote attackers to execute code via a crafted Silverlight application.

Added to KEV: 2022-05-25Federal patch deadline: 2022-06-15⚠ USED IN RANSOMWARE CAMPAIGNS

Required Action (CISA)

The impacted product is end-of-life and should be disconnected if still in use.

Risk Analysis

Microsoft Silverlight is vulnerable to a pointer validation flaw during HTML object rendering, which allows remote attackers to execute arbitrary code. The high EPSS score of 0.93054 indicates a strong likelihood of exploitation, and its inclusion in CISA's KEV catalog confirms it is actively being exploited. This poses a significant risk to systems still using Silverlight.

This vulnerability is actively exploited in the wild, indicating that attackers are leveraging it to compromise systems. The flaw is remotely exploitable, allowing for attacks via crafted Silverlight applications.

Recommended Action

Microsoft Silverlight is deprecated and should be uninstalled from all systems where it is not strictly necessary. If uninstallation is not possible, ensure all instances are updated to the latest available secure version and restrict its use.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2013-0074 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2013-0074 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
