DESCRIPTION:
Aliaksandr Hartsuyeu has discovered a vulnerability in SZUserMgnt,
which can be exploited by malicious people to conduct SQL injection
attacks.

Input passed to the "username" parameter in "login.verify.php" isn't
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been confirmed in version 1.4. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
