Authenticated arbitrary file deletion
Published Aug 11, 2021 · Updated Aug 4, 2024
Maccms10 arbitrary file deletion allows remote authenticated users to delete files through the administrative attachment deletion endpoint. The admin images deletion handler accepts a user-controlled ids[] path containing traversal segments and passes it to file deletion, allowing paths such as install.lock or admin.php to be removed. Administrative authentication is required; deleting install.lock can enable site reinstallation, while deleting application files can interrupt or compromise service.
