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 shares user credentials plain text between the device and the user source device during the login process.

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.

Advantech ADAM-5630 has built-in commands that can be executed without authenticating the user. These commands allow for restarting the operating system, rebooting the hardware, and stopping the execution. The commands can be sent to a simple HTTP request and are executed by the device automatically, without discrimination of origin or level of privileges of the user sending the commands.
