Vulnerability from variot - Updated: 2025-09-24 23:05

D-Link DIR-X3260 prog.cgi SetDynamicDNSSettings Stack-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-X3260 routers. Authentication is required to exploit this vulnerability.

The specific flaw exists within the prog.cgi binary, which handles HNAP requests made to the lighttpd webserver listening on TCP ports 80 and 443. The issue results from the lack of proper validation of a user-supplied string before 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-21590. D-Link Systems, Inc. of dir-x3260 An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The D-Link DIR-X3260 is a mainstream Wi-Fi 6-supported router from D-Link, model DIR-X3260 AX3200
