Proxy accepts CONNECT requests to itself

Vulnerability Assessment Summary
Connects back to the web proxy through itself

Detailed Explanation for this Vulnerability Assessment
The proxy permits the users to perform
repeated CONNECT requests to itself.

This permit anybody to saturate the proxy CPU, memory or
file descriptors.

** Note that if the proxy limits the number of connections
** from a single IP (e.g. acl maxconn with Squid), it is
** protected against saturation and you may ignore this alert.

Solution: reconfigure your proxy so that
it refuses CONNECT requests to itself.

Network Security Threat Level: Medium
