SV-99869r1_rule Lighttpd must limit the number of simultaneous requests.

Vulnerability discussion

Resource exhaustion can occur when an unlimited number of concurrent requests are allowed on a web site, facilitating a denial of service attack. Mitigating this kind of attack will include limiting the number of concurrent HTTP/HTTPS requests.Lighttpd is used for administrative purposes only. Lighttpd provides the maxConnections attribute of the <Connector Elements> to limit the number of concurrent TCP connections.

Check content

At the command prompt, execute the following command: grep 'server.max-connections = 1024' /opt/vmware/etc/lighttpd/lighttpd.conf If the "server.max-connections" is not set to "1024", commented out, or does not exist, this is a finding.

Fix text

Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf Configure the "lighttpd.conf" file with the following value: server.max-connections = 1024

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.
