The integrated web server on port 4842\u002Ftcp of the affected products could allow a remote attacker to execute code with privileged permissions on the system by sending specially crafted network requests to port 4842\u002Ftcp. Please note that this vulnerability is only exploitable if port 4842\u002Ftcp is manually opened in the firewall configuration of network port X130. The security vulnerability could be exploited by an attacker with network access to the affected devices on port 4842\u002Ftcp. Successful exploitation requires no privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the web server.
