Detection Guidance

This vulnerability can be detected by identifying if your system is running a vulnerable version of ImageMagick prior to 7.1.2-12. You can check the installed ImageMagick version using the command `magick -version` or `convert -version`. Additionally, monitoring for crashes or denial-of-service symptoms when processing SVG or MVG files may indicate exploitation attempts. Since the vulnerability is triggered by processing crafted MVG files, inspecting logs or network traffic for suspicious MVG or SVG file uploads or conversions could help detect attempts. There are no specific detection commands provided in the resources. [2]
