The remote host is running Ultimate PHP Board (UPB).

There is a flaw in this version which may allow an attacker
to execute arbitrary code on this host, by sending a malformed
user-agent which contains PHP commands.  Once the user-agent
has been sent, it is stored in the logs. When the administrator
of this web site will read the logs through admin_ip.php,
the code will be executed.

Solution : Upgrade to the latest version of this CGI
