Authenticated code execution via unrestricted PHP upload
Published Sep 20, 2023 · Updated Sep 25, 2024
Unrestricted file upload in EliteCMS 1.01 allows remote authenticated users to execute arbitrary PHP code through manage_uploads.php. The administrative upload handler accepts a .php file and stores it beneath the web-accessible /uploads path without blocking its executable type. Access to the administrative interface is required; requesting the stored file causes the web server to run attacker-supplied PHP with its service privileges.
