CVE-2022-30037Public exploitNetwork attack vector

Authenticated PHP code execution via cron configuration write

Published Mar 23, 2023 · Updated Feb 25, 2025

Code injection in XunRuiCMS 4.3.3 through 4.5.1 allows remote authenticated users to execute arbitrary PHP through the cron task editor. The Admin Cron.php add() function writes unsanitized task data into WRITEPATH/config/cron.php, which the CMS later includes as executable PHP. Administrator access or permission to manage Application > Task Queue is required, and successful exploitation runs code in the web server context.
