Vulnerability discussion

Lighttpd will only allow or deny script execution based on file extension. The ability to control script execution is controlled with the cgi.assign variable in lighttpd.conf. For script mappings, the ISSO must document and approve all allowable file extensions the web site allows (whitelist). The whitelist will be compared to the script mappings in Lighttpd.

Check content

Obtain supporting documentation from the ISSO. Determine the scripts that are deemed necessary and approved (whitelist). Note: Lighttpd provides the cgi.assign parameter to specify script mappings. Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf file Navigate to the cgi.assign parameter. If cgi.assign parameter is configured with script types that are deemed for denial, this is a finding.

Fix text

Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf file Navigate to the cgi.assign parameter. Configure the cgi.assign parameter with the scripts that are deemed necessary and approved (whitelisted).

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.
