Vulnerability discussion

The web server must be configured to listen on a specified IP address and port. Without specifying an IP address and port for the web server to use, the web server will listen on all IP addresses available to the hosting server. If the web server has multiple IP addresses, i.e., a management IP address, the web server will also accept connections on the management IP address.Accessing the hosted application through an IP address normally used for non-application functions opens the possibility of user access to resources, utilities, files, ports, and protocols that are protected on the desired application IP address.

Check content

Review the <'INSTALLED PATH'>\conf\httpd.conf file and search for the following directive: Listen For any enabled "Listen" directives, verify they specify both an IP address and port number. If the "Listen" directive is found with only an IP address or only a port number specified, this is finding. If the IP address is all zeros (i.e. 0.0.0.0:80 or [::ffff:0.0.0.0]:80), this is a finding. If the "Listen" directive does not exist, this is a finding.

Fix text

Edit the <'INSTALLED PATH'>\conf\httpd.conf file and set the "Listen" directive to listen on a specific IP address and port.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
