Tim Weber has discovered two vulnerabilities in deV!L'z Clanportal, which can be exploited by malicious people to compromise a vulnerable system and manipulate data.

1) The upload/index.php script fails to validate the extension of an uploaded file. This can be exploited to upload files with the ".php" extension and execute arbitrary PHP code on the server.

Successful exploitation requires passing an allowed MIME media type in the HTTP headers and creating a file that is both a syntactically correct PHP script and a JPEG or GIF image that the PHP function getimagesize() will consider correct.

2) Input passed to the "show" parameter in sites/index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation reportedly allows granting a user administrator privileges, but requires that "magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 1.3.6. Other versions may also be affected.

Solution
Update to version 1.3.6.1.
