SV-76961r1_rule ColdFusion must enable UUID for session identifier generation.

Vulnerability discussion

Unique session IDs are the opposite of sequentially generated session IDs, which can be easily guessed by an attacker. Unique session identifiers help to reduce predictability of session identifiers. Unique session IDs address man-in-the-middle attacks, including session hijacking or insertion of false information into a session. If the attacker is unable to identify or guess the session information related to pending application traffic, they will have more difficulty in hijacking the session or otherwise manipulating valid sessions.ColdFusion offers session ID randomness and uniqueness by enabling UUID for the session ID. Without this option enabled, session values are sequential and become easy to hijack through guessing.

Check content

Within the Administrator Console, navigate to the "Settings" page under the "Server Settings" menu. If "Use UUID for cftoken" is not checked, this is a finding.

Fix text

Navigate to the "Settings" page under the "Server Settings" menu. Check "Use UUID for cftoken" and select the "Submit Changes" button.

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.
