CVE-2020-10945Known exploitationPublic exploit

Session hijacking via identifiers exposed in responses

Published May 27, 2020 · Updated Aug 4, 2024

Information disclosure in Centreon before 19.10.7 allows remote attackers to obtain authenticated users' session IDs from HTTP responses. Event Log, Host Monitoring, and selected main.get.php responses embed the active session identifier instead of keeping it server-side. Exploitation requires visibility into a logged-in user's response, such as through a separate XSS flaw, after which the session ID permits account impersonation.
