Loading vulnerability…
A vulnerability in the PostScript (PS) Interpreter component of Ghostscript versions 9.18 and 9.20 allows remote attackers to execute arbitrary code. The issue arises due to improper handling of crafted userparams, which can be exploited to gain code execution within the context of the Ghostscript process.

This repository contains a single Metasploit module: 'ImageMagick Delegate Arbitrary Command Execution' (modules/exploits/unix/fileformat/imagemagick_delegate.rb). The module exploits command injection vulnerabilities in the way ImageMagick processes 'delegate' commands for file conversions, affecting versions <= 7.0.1-0 and <= 6.9.3-9 (legacy). The exploit works by generating a malicious image file (SVG, MVG, or PS) that, when processed by a vulnerable ImageMagick installation, executes arbitrary shell commands supplied by the attacker. The module supports multiple file formats and vectors, including a popen() vector and a Ghostscript delegate bypass. The payload is customizable via the Metasploit framework and is encoded to avoid problematic characters. The only notable file path in the code is '/dev/tty', used as a placeholder in the template mechanism. The module references CVE-2016-3714 and CVE-2016-7976, and is weaponized for operational use within Metasploit. The repository is structured as a typical Metasploit exploit module, with all logic contained in a single Ruby file.
