Vulnerability discussion

Network device management web interfaces utilize sessions and session identifiers to control management interface behavior and administrator access. If an attacker can guess the session identifier or can inject or manually insert session information, the session may be compromised.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.

Check content

If the network device uses a web interface for device management, determine if it recognizes only system-generated session identifiers. This requirement may be verified by demonstration, configuration review, or validated test results. If the network device recognizes other session identifiers than the system-generated ones, this is a finding.

Fix text

Configure the network device to recognize only system-generated session identifiers.

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.
