CVE-2020-29030Public exploitNetwork attack vector

Session hijacking via URL-exposed authentication tokens

Published Mar 5, 2021 · Updated Sep 17, 2024

Information exposure in Secomea GateManager before 9.4 allows remote attackers to hijack authenticated sessions through leaked tokens. After login, its web GUI places the authentication token in the URL path of every subsequent GET and POST request, exposing it to browser history, Referer headers, and web logs. Exploitation requires obtaining a recorded or forwarded URL from an authenticated user's session; the token alone opens restricted pages with that session's authority.
