HTTP Proxy CONNECT Loop DoS

This script is Copyright (C) 2005-2013 Tenable Network Security, Inc.


Synopsis :

The remote proxy may be vulnerable to a denial of service.

Description :

The proxy allows the users to perform repeated CONNECT requests to
itself.

This allow 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.

Risk factor :

Medium / CVSS Base Score : 5.0
