CVE-2022-41751Public exploit

Local command execution via shell-interpreted filename

Published Oct 17, 2022 · Updated May 13, 2025

OS command injection in Jhead 3.06.0.1 allows local users to execute arbitrary commands by regenerating a JPEG thumbnail with a crafted filename. RegenerateThumbnail passes a shell command containing the unvalidated filename to system(), so shell metacharacters in the name become executable syntax. Exploitation requires a JPEG with an EXIF thumbnail and a user to invoke the -rgt50 option; commands run with that user's privileges.
