Summary

REDAXO before 5.21.5 has insufficient session expiration (CWE-613), so sessions stay valid after a password change. An attacker who holds a user's session id or stay-logged-in cookie keeps backend access after the password change, and the cookie remains valid for up to three months. Exploitation requires the attacker to first obtain one of these values.
