CVE-2022-45139
A CORS Misconfiguration in the web-based management allows a malicious third party webserver to misuse all basic information pages on the webserver. In combination with CVE-2022-45138 this could lead to disclosure of device information like CPU diagnostics. As there is just a limited amount of information readable the impact only affects a small subset of confidentiality.

If an immediate firmware update is not possible, the only way to prevent an attack is to prevent the access of the Web Based Management tool from the internet. This can be achieved by using a network element, such as a router, which hides and secures the components from the internet.
