CVE-2023-32725Network attack vector

Session hijacking via URL widget cookie forwarding

Published Dec 18, 2023 · Updated Aug 2, 2024

Session cookie disclosure in affected Zabbix releases allows remote attackers to hijack frontend sessions through a URL widget. When an Admin or Super admin tests or schedules a report containing a dashboard URL widget, the server sends the report creator's zbx_session cookie to the widget's configured website. Control of that website and the required user interaction expose the creator's active session, granting the same frontend privileges without revealing other users' cookies.
