The remote host is vulnerable to multiple attack vectors.
The remote host is running the Mambo Content Server, an application for generating dynamic content for web servers. The remote application is vulnerable to a flaw where remote attackers can upload malicious code. The code can then be executed by simply requesting the code via an HTTP session. The specific flaw is within the Tar.php script, which does not properly sanitize user-supplied content. Versions of Mambo through 18.104.22.168 are prone to a remote 'file include' flaw. An attacker exploiting this flaw would be able to specify malicious code that would be run by the Mambo server.
Upgrade to a version of Mambo higher than 4.5.2.
