Authenticated RCE via compression plug-in command injection

Published Sep 19, 2023 · Updated Sep 24, 2024

Command injection in Openu alter Stable 0.4.3 allows remote authenticated users to execute arbitrary commands through its compression plug-in. compress-inc.php executes the administrator-supplied plug-in command during an upload without restricting it to a safe executable. Administrative plug-in access is required, and successful exploitation runs commands with the web server process privileges.
