CVE-2022-26149Public exploitNetwork attack vector

Administrator code execution via enabled PHP uploads

Published Feb 26, 2022 · Updated Aug 3, 2024

Unrestricted file upload in MODX Revolution 2.8.3-pl and earlier allows remote authenticated users to execute arbitrary code. An administrator can add PHP to the Uploadable File Types setting, then use Media Browser to place a PHP web shell in a web-accessible location. Administrative access is required, and PHP uploads are disabled by default; successful exploitation runs attacker-supplied code as the web-server account.
