CVE-2025-70973Public exploitNetwork attack vector

Session hijacking via unchanged pre-login JSESSIONID

Published Mar 9, 2026 · Updated Mar 9, 2026

Session fixation in ScadaBR 1.12.4 allows remote attackers to hijack authenticated sessions through a known pre-login cookie. The web application issues JSESSIONID before authentication and retains that identifier after successful login instead of creating a new session. Exploitation requires knowledge of the victim's pre-login identifier and grants access to authenticated SCADA monitoring and functions until logout or expiration.
