A file-rename filter bypass exists in admin/media/rename.php in WBCE CMS 1.4.0 and earlier. This can be exploited by an authenticated user with admin privileges to rename a media filename and extension. (For example: place PHP code in a .jpg file, and then change the fileβs base name to filename.ph and change the fileβs extension to p. Because of concatenation, the name is then treated as filename.php.) At the result, remote attackers can execute arbitrary PHP code.
