CRITICAL:
Moderately critical

IMPACT:
Manipulation of data

WHERE:
>From remote

SOFTWARE:
Flexcustomer 0.0.x

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

Input passed to the "username" and "password" parameters in index.php
and to the "checkuser" and "checkpass" parameters in /admin/index.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 0.0.4. Other versions
may also be affected.

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