Session Fixation vulnerabilities allow an attacker to fix a users session identifier before login providing an opportunity for session takeover on a product. Affected products: ABB ASPECT - Enterprise v3.08.02; NEXUS Series v3.08.02; MATRIX Series v3.08.02
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
