Crítica

VetorAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
MaxSite CMS through 109.6 ships with a hardcoded session encryption key in application/config/config.php that is never changed during installation, allowing unauthenticated attackers to forge administrator session cookies. Attackers can mint a malicious ci session cookie with administrator privileges by computing an HMAC-SHA1 using the publicly known encryption key, bypassing authentication checks in is login() and mso check allow() functions.
