Descriptions

The affected product’s configuration is vulnerable due to missing authentication, which may allow an attacker to change configurations and execute arbitrary code on the iView (versions prior to v5.7.03.6182).

La configuración del producto afectado es vulnerable debido a una falta de autenticación, lo que puede permitir a un atacante cambiar la configuración y ejecutar código arbitrario en el iView (anterior a versión v5.7.03.6182)

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech iView. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the runProViewUpgrade action of NetworkServlet, which listens on TCP port 8080 by default. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the service acccount.
