Name of the Vulnerable Software and Affected Versions osClass version 3.6.1

Description The issue allows for directory traversal via the plugin parameter, which can be exploited for remote PHP code execution. An administrator can upload an image containing PHP code in the EXIF data through the "index.php?page=ajax&action=ajax upload" endpoint.
