Title

ColdFusion must enable UUID for session identifier generation. (Cat II impact)

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.
