Input passed to the "REMOTE_ADDR" and "msg[x][0]" cookies in error.php is not properly sanitised before being stored in .inc files. This can be exploited to execute arbitrary PHP code by requesting the .inc file through error.php. The vulnerabilities are confirmed in version 4.5.16. Other versions may also be affected.
