The remote host is vulnerable to multiple attack vectors.
The remote host is running Geeklog, an open-source weblog powered by PHP and MySQL. The installed version of Geeklog is vulnerable to both Cross-Site Scripting and SQL Injection flaws. An attacker exploiting the SQL injection flaw would be able to execute arbitrary SQL commands on the backend database server. Exploitation of the XSS flaws would enable the attacker to execute script code within the vulnerable user's browser.
Upgrade to version 1.4.0sr3 or higher.
