This Metasploit module exploits a format string vulnerability in Ghostscript versions before 10.03.1 to achieve a SAFER sandbox bypass and execute arbitrary commands. This vulnerability is reachable via libraries such as ImageMagick. This exploit only works against Ghostscript versions 10.03.0 and 10.01.2. Some offsets adjustment will probably be needed to make it work with other versions.

An attacker could use this issue to bypass SAFER restrictions and cause unspecified impact. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.10. Thomas Rinsma discovered that Ghostscript did not prevent changes to uniprint device argument strings after SAFER is activated, resulting in a format-string vulnerability. An attacker could possibly use this to execute arbitrary code.
