CVE-2026-5815 is a remotely exploitable stack-based buffer overflow affecting D-Link DIR-645 firmware versions 1.01, 1.02, and 1.03. The flaw is located in the hedwigcgi_main function within the router's CGI component, /cgi-bin/hedwig.cgi. Improper handling of attacker-controlled input can cause memory corruption on the stack, which may crash the process and can potentially be leveraged for further exploitation depending on runtime protections and exploit reliability. The issue is exposed over the network and public exploit material is available. The affected product line is no longer supported by the vendor.
