The remote host is vulnerable to an HTML Injection attack.
The remote host is running CopperMine Gallery, a set of PHP scripts to handle galleries of pictures. There is a flaw in this version of Coppermine Gallery. Specifically, the x-forwarded-for variable is not properly parsed by the application. An attacker exploiting this flaw can inject HTML or script into a browser session. Typically, exploiting this flaw involves convincing a user to browse to a malicious URI. Successful exploitation results in a potential loss of confidential data (such as cookies).
Upgrade to version 1.3.3 or higher.
