Description

Open proxies allow malicious clients to mount attacks which originate from the IP of the proxy server, without requiring the attacker to authenticate to the proxy first.

Additionally, an open proxy may allow an attacker to access an internal network which would be otherwise secure.

Steps should be taken to correctly configure the proxy server such that unauthorized connections are denied.

Solution(s)

  • squid-disable-default-open-proxy
  • microsoft-isa-disable-default-open-proxy

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
