Discussion

Squid Web Proxy Reverse Proxy Vulnerability

Squid is a free client-side web proxy that retrieves cached web pages for quick browsers and a reduction in bandwidth consumption.

Squid servers, when configured as an "HTTP accelerator only", may allow remote attackers to use them as port scanners. There is also a potential that they will grant proxied access to the malicious user.

It should be noted that this is not a default configuration for affected versions of Squid Web Proxy.
