The remote host seems to be running YaPiG, an Image Gallery script written in PHP.

The remote version of this software contains a flaw that can let a malicious user 
view images in password protected directories.

Successful exploitation of this issue may allow an attacker to access unauthorized 
images on a vulnerable server.

Solution : Update to newer or disable this CGI suite
