The remote host is vulnerable to a SQL injection attack.
The remote host is running FlexCMS, a content management system written in PHP. The installed version of FlexCMS is earlier than 3.0. Such versions are potentially affected by a SQL injection vulnerability in the 'CookieUsername' cookie parameter. An attacker, exploiting this flaw, may be able to compromise the application. Note, that this requires magic_quotes_gpc to be turned off.
Upgrade to FlexCMS 3.0 or later.
