CVE-2023-44408: Dlink dap-1325 firmware stack-based buffer overflow vulnerability

Dlink · Dap 1325 Firmware

D-Link DAP-1325 SetAPLanSettings IPAddr Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1325 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of XML data provided to the HNAP1 SOAP endpoint. 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-18827.
