Description
A web server should be primarily a web server or a proxy server but not both, for the same reasons that other multi-use servers are not recommended. Scanning for web servers that will also proxy requests into an otherwise protected network is a very common attack making the attack anonymous.

Review the web server documentation and deployed configuration to determine if the web server is also a proxy server. If the web server is also acting as a proxy server, this is a finding.

Fix Text (F-6637r377721_fix)
Uninstall any proxy services, modules, and libraries that are used by the web server to act as a proxy server. Verify all configuration changes are made to assure the web server is no longer acting as a proxy server in any manner.
