CVE-2020-36913Public exploitNetwork attack vector

Authentication bypass via fixated PHP session identifier

Published Jan 6, 2026 · Updated Jan 6, 2026

Session fixation in All-Dynamics Software enlogic:show 2.0.2 allows remote attackers to bypass authentication through a fixed PHP session. The welcome.php login flow places a random PHP session identifier in a GET URL and accepts an attacker-supplied value without replacing it after login. Exploitation requires a victim to authenticate through the crafted request, after which the attacker can reuse the authenticated session for actions permitted to that victim.
