CVE-2023-22479Network attack vector

Account hijacking via unrotated login session cookie

Published Jan 10, 2023 · Updated Mar 10, 2025

Session fixation in KubeOperator KubePi 1.6.3 and earlier allows remote attackers to hijack user accounts through a preset cookie. The Login handler accepts an existing SESS_COOKIE_KUBEPI value when starting the authenticated session instead of removing it and issuing a fresh identifier. Exploitation requires a user to log in with an attacker-known cookie, after which that identifier grants access to the resulting authenticated session.
