What is CVE-2023-50208?

A stack-based buffer overflow vulnerability has been identified in the D-Link G416 routers, specifically within the HTTP service that operates on TCP port 80. Attackers on the same network segment can exploit this flaw due to inadequate validation of user-supplied data length before it is copied to a fixed-length stack buffer. This oversight potentially allows attackers to execute arbitrary code with root privileges, promoting significant security risks for affected installations. No authentication is necessary for exploitation, further increasing the vulnerability's threat level.

Affected Version(s)

G416 1.08b02
