Moubik has discovered a vulnerability in Mihalism Multi Host, which can be exploited by malicious people to conduct SQL injection attacks.

Input passed to the "username" parameter in users.php (when "act" is set to "lost_password_go") 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 allows e.g. retrieving administrator password hashes, but requires that "magic_quotes_gpc" is disabled.

Solution
Update to a version released later than 2008-02-21.
