CVE-2024-11317Network attack vector

Unauthenticated session takeover via fixed PHP identifiers

Published Dec 5, 2024 · Updated Dec 5, 2024

Session fixation in ABB ASPECT-Enterprise, NEXUS Series, and MATRIX Series 3.08.02 and earlier allows remote attackers to hijack sessions. The PHP login flow retains a session identifier fixed before authentication instead of regenerating it after successful login. Exploitation requires network access and a victim to authenticate with the fixed identifier, after which the attacker can reuse the authenticated session.
