The vulnerability is caused due to the wp-content/plugins/font-uploader/font-upload.php script improperly validating the extension of an uploaded file. This can be exploited to execute arbitrary PHP code by uploading a PHP file with an appended ".ttf" or ".otf" file extension. Successful exploitation requires that Apache is not configured to handle the mime-type for media files with a ".ttf" or ".otf" extension (not configured by default). The vulnerability is confirmed in version 1.2.4. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly verified.
