Vulnerability discussion

During the initial setup of a Transport Layer Security (TLS) connection to the web server, the client sends a list of supported cipher suites in order of preference. The Lighttpd will reply with the cipher suite it will use for communication from the client list. If an attacker can intercept the submission of cipher suites to the web server and place, as the preferred cipher suite, a weak export suite, the encryption used for the session becomes easy for the attacker to break, often within minutes to hours.

Check content

At the command prompt, execute the following command: grep '^ssl.cipher-list' /opt/vmware/etc/lighttpd/lighttpd.conf If the value returned in not "ssl.cipher-list = "FIPS: +3DES:!aNULL" "or is commented out, this is a finding.

Fix text

Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf Configure the lighttpd.conf file with the following: ssl.cipher-list = "FIPS: +3DES:!aNULL"

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.
