CVE-2024-5294

D-Link DIR-3040 prog.cgi websSecurityHandler Memory Leak Denial-of-Service Vulnerability. This vulnerability allows network-adjacent attackers to create a denial-of-service condition on affected installations of D-Link DIR-3040 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the prog.cgi program, which handles HNAP requests made to the lighttpd webserver listening on ports 80 and 443. The issue results from the lack of proper memory management when processing HTTP cookie values. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. . Was ZDI-CAN-21668.
