Description

OneNav v1.2.4 contains an authenticated arbitrary file deletion vulnerability in the Api::upload() method in class/Api.php. An authenticated administrator can submit a non-HTML upload filename matching an existing file in the application's working directory. The application passes the user-controlled filename to unlink() when rejecting the upload, potentially causing file deletion and denial of service.
