CISA KEV Advisory
ImageMagick Improper Input Validation Vulnerability
ImageMagick contains an improper input validation vulnerability that affects the EPHEMERAL, HTTPS, MVG, MSL, TEXT, SHOW, WIN, and PLT coders. This allows a remote attacker to execute arbitrary code via shell metacharacters in a crafted image.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
ImageMagick contains an improper input validation vulnerability affecting several coders, allowing a remote attacker to execute arbitrary code. This can be achieved by injecting shell metacharacters into a crafted image file. The high EPSS score of 0.93749 and its inclusion in the KEV catalog signify a high likelihood of exploitation and confirmed active attacks.
This vulnerability has been actively exploited in the wild and is listed in CISA's Known Exploited Vulnerabilities catalog. It is remotely exploitable through specially crafted image files.
Users of ImageMagick should update to the latest patched version. Implement robust input validation and sanitize all user-supplied image data before processing.
Technical Analysis
CVE-2016-3714 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-2016-3714 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.
