Usable remote proxy on any port

Vulnerability Assessment Summary
Acertains if we can use the remote web proxy against any port

Detailed Explanation for this Vulnerability Assessment
The proxy, permits everyone to perform requests
against arbitrary ports, like
'GET http://cvs.nessus.org:110'.
This problem may permit attackers to go through your
firewall, by connecting to sensitive ports like 25 (sendmail)
using your proxy. In addition to that, your proxy may be used
to perform attacks against other networks.

Solution: reconfigure your proxy so that it only accepts
connections against non-dangerous ports (> 1024).
