What is CVE-2023-32152?

A vulnerability exists in the web management interface of D-Link DIR-2640 routers that enables attackers to bypass authentication altogether. This security flaw allows network-adjacent attackers to send specially crafted requests that can gain unauthorized access to the router's settings without the need for valid login credentials. The exploited route listens on TCP port 80 by default, which exposes it to potential threats if not adequately secured. Various security recommendations should be considered to mitigate risks associated with this vulnerability.
