What is CVE-2019-6584?

A session management issue has been identified in SIEMENS LOGO!8 devices where the integrated web server fails to invalidate the Session ID upon user logout. This flaw allows an attacker with access to the network or who can read communication between the device and the user to exploit valid Session IDs, continuing access even after legitimate user logout. Given the severity of this oversight, it highlights the need for stringent session management practices to ensure user sessions are appropriately terminated.
