In a recent APT Simulation engagement, the Ocelot team identified that ImageMagick was used to process images in a Drupal-based website, and hence, the team decided to try to find new vulnerabilities in this component, proceeding to download the latest version of ImageMagick, 7.1.0-49 at that time. As a result, two zero days were identified:
- CVE-2022-44267: ImageMagick 7.1.0-49 is vulnerable to Denial of Service. When it parses a PNG image (e.g., for resize), the convert process could be left waiting for stdin input.
- CVE-2022-44268: ImageMagick 7.1.0-49 is vulnerable to Information Disclosure. When it parses a PNG image (e.g., for resize), the resulting image could have embedded the content of an arbitrary remote file (if the ImageMagick binary has permissions to read it).
