What is CVE-2022-43622?

A vulnerability in D-Link DIR-1935 routers allows network-adjacent attackers to execute arbitrary code. The flaw arises from inadequate validation of user-supplied data in the Login request handling of the web management portal. Attackers can exploit this issue by leveraging the HNAP_AUTH header, leading to the potential execution of code with root privileges, making affected systems vulnerable to exploitation without authentication. It is crucial for users to implement the latest security updates to mitigate this risk.
