What is CVE-2023-41228?

A stack-based buffer overflow vulnerability exists in the prog.cgi binary of D-Link DIR-3040 routers, impacting their web server functionality. This flaw allows network-adjacent attackers to execute arbitrary code on affected systems once they have authenticated. The vulnerability arises from insufficient validation of a user-supplied string, which can lead to the overwriting of the stack, potentially granting elevated privileges to an attacker. Security measures and updates are crucial to mitigate any risks associated with this vulnerability.
