H-T TeaM have discovered some vulnerabilities in minimal Gallery, which can be exploited by malicious people to disclose sensitive information.

1) Input passed to the "thumb" and "thumbcat" parameters in _mg/php/mg_thumbs.php is not properly sanitised before being used. This can be exploited to display arbitrary files through directory traversal attacks.

2) It is possible to view certain system information returned by the "phpinfo()" function by accessing the php_info.php script directly.

The vulnerabilities are confirmed in version 0.8. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised. Restrict access to php_info.php (e.g. with ".htaccess").
