Summary

Artica Proxy before version 4.50.000000 Service Pack 7 (fixed in hotfix 20260724-02) contains a session fixation vulnerability that allows unauthenticated attackers to hijack administrative sessions by setting a known PHPSESSID on a victim's browser prior to authentication. Attackers can pre-set a controlled session identifier and wait for a victim to authenticate through fw.login.php, after which the attacker gains a fully authenticated administrative session on port 9000.

Risk Assessment

The organization is at risk of administrative session hijacking, potentially leading to full compromise of the proxy server and access to the internal network.

Recommendation

Immediately upgrade Artica Proxy to version 4.50.000000 Service Pack 7 with hotfix 20260724-02 or later.
