Advantech ADAM-5630 Use of Persistent Cookies Containing Sensitive Information

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-5550 Cross-site Scripting

Advantech ADAM 5550's web application includes a "logs" page where all the HTTP requests received are displayed to the user. The device doesn't correctly neutralize malicious code when parsing HTTP requests to generate page output.

Advantech ADAM-5630 Weak Encoding for Password

Advantech ADAM-5630 shares user credentials plain text between the device and the user source device during the login process.

Advantech ADAM-5550 Weak Encoding for Password

Advantech ADAM-5550 share user credentials with a low level of encryption, consisting of base 64 encoding.

Advantech ADAM-5630 Cross-Site Request Forgery

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.
