Security Bulletin: IBM Security Verify Information Queue does not sufficiently safeguard session IDs from session fixation attacks (CVE-2021-20411)

Security Bulletin


Summary

The web server in IBM Security Verify Information Queue (ISIQ) does not always update the session identifier when a new user logs in. This could allow a session fixation attack in which a previously used session identifier gets commandeered by an impersonator. As of v10.0.0, ISIQ now consistently generates a new session identifier for each login to prevent a session fixation attack.
