CVE-2026-66745

Artica Proxy before 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.

Summary		(es) Artica Proxy antes de 4.50.000000 Service Pack 7 (corregido en el hotfix 20260724-02) contiene una vulnerabilidad de fijación de sesión que permite a atacantes no autenticados secuestrar sesiones administrativas estableciendo un PHPSESSID conocido en el navegador de una víctima antes de la autenticación. Los atacantes pueden preestablecer un identificador de sesión controlado y esperar a que una víctima se autentique a través de fw.login.php, después de lo cual el atacante obtiene una sesión administrativa completamente autenticada en el puerto 9000.
