CVE-2023-50211: D-Link G416 httpd API-AUTH Timestamp Processing Stack-based Buffer Overflow Remote Code Execution Vulnerability
D-Link G416 httpd API-AUTH Timestamp Processing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link G416 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the HTTP service listening on TCP port 80. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21663.
