The remote host is vulnerable to several injection attacks.
According to its version number, the remote host is running a version of PHP-Fusion that suffers from an HTML Injection flaw. An attacker exploiting these flaws would be able to inject code that would be executed either by the target web server or by unsuspecting users browsing the website. In addition, this version of PHP-Fusion may be vulnerable to a SQL injection attack.
Upgrade to version 6.00.205 or higher.
