Cookies of authenticated Advantech ADAM-5630 users remain as active valid cookies when a
session is closed. Forging requests with a legitimate cookie, even if
the session was terminated, allows an unauthorized attacker to act with
the same level of privileges of the legitimate user.
Advantech ADAM-5630 contains a cross-site request forgery (CSRF) vulnerability. It allows an attacker to partly circumvent the same
origin policy, which is designed to prevent different websites from
interfering with each other.
