Discussion

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.

Fix Text

Determine where the proxy modules are located by running the following command: grep -rl "proxy_module" <'INSTALL PATH'> Edit the file and comment out the following modules: proxy_module proxy_ajp_module proxy_balancer_module proxy_ftp_module proxy_http_module proxy_connect_module Comment out the ProxyRequext directive in the httpd.conf file. Restart Apache: apachectl restart

Check Content

If the server is a proxy server and not a web server, this check is Not Applicable. In a command line, run "httpd -M | sort" to view a list of installed modules. If any of the following modules are present, this is a finding: proxy_module proxy_ajp_module proxy_balancer_module proxy_ftp_module proxy_http_module proxy_connect_module Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V | egrep -i 'httpd_root|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Search for the directive "ProxyRequest" in the "httpd.conf" file. If the ProxyRequest directive is set to “On”, this is a finding.
