which can be exploited by malicious people to disclose sensitive
information.

Input passed to the "lang" and "prevlang" parameters in php/login.php
and to the "prevlang" parameter in  php/internal-init.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.
