DescriptionCVE.org

ImageMagick before 7.1.2-24 contains an incorrect policy check that allows attackers to create or truncate files disallowed by security policies. Remote attackers can bypass path policy restrictions in sandboxed conversion services to write arbitrary files outside intended boundaries.

AnalysisAI

ImageMagick before 7.1.2-24 fails to correctly enforce path restrictions configured in its security policy (policy.xml), enabling file creation and truncation outside designated filesystem boundaries. In sandboxed image conversion services - a common deployment pattern for web applications accepting user-submitted images - this incorrect policy check can be exploited by attackers who submit crafted images to write arbitrary files accessible to the conversion process. No public exploit has been identified at time of analysis and this is not listed in CISA KEV, but the wide use of ImageMagick in web application stacks makes the affected population substantial.

Technical ContextAI

ImageMagick (CPE: cpe:2.3:a:imagemagick:imagemagick) is a widely used open-source image manipulation toolkit. It supports a security policy framework via policy.xml, which allows operators to restrict accessible file paths, image coders, and resource limits - a mechanism commonly relied upon by sandboxed multi-tenant conversion pipelines. The root cause is CWE-22 (Path Traversal): the path validation logic in the policy enforcement layer does not correctly evaluate configured path restrictions, allowing traversal to filesystem locations that policy.xml was intended to prohibit. The provided CVSS 4.0 vector specifies AV:L/PR:L, implying the attack requires at minimum low-privilege access to the service or local environment; however, the description explicitly references remote attackers via network-accessible conversion services - a discrepancy that warrants vendor clarification.

RemediationAI

Upgrade to ImageMagick 7.1.2-24 or later, as documented in the vendor advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-gm48-c7f2-v67p. Until patching is complete, note that policy.xml path restrictions alone are insufficient as a compensating control because the policy check itself is the vulnerable component. Instead, enforce filesystem confinement at the OS level using AppArmor or SELinux to restrict the ImageMagick process user to only the directories it legitimately requires - this provides independent enforcement orthogonal to ImageMagick's own policy engine. Running conversion services inside minimal containers or chroot environments limits the blast radius of any unauthorized file writes to the container's filesystem. Restricting coder access via policy.xml to known-safe formats (disabling MVG, SVG, MSL, and similar delegate-invoking formats) reduces the attack surface of the conversion pipeline more broadly, though it does not directly address the path validation flaw. These mitigations carry the trade-off of potential conversion failures if format or path restrictions are overly aggressive.
