CVE-2024-28144Public exploitNetwork attack vector

Unauthenticated session takeover via client-derived identifier

Published Dec 12, 2024 · Updated Nov 3, 2025

Session fixation in Image Access GmbH Scan2Net 7.42B and earlier allows remote attackers to take over a logged-in user's web session. The custom session algorithm derives SID1 from the request IP address and User-Agent plus the scanner hostname, then compares it with one database-stored current session. Reachability requires an active victim session and either a shared source IP or spoofed IP and matching User-Agent; success grants the victim's application role.
