CVE-2023-32141: dap-1360 Stack Overflow — Fix

Description

D-Link DAP-1360 webproc WEB_DisplayPage 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-1360 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of requests to the /cgi-bin/webproc endpoint. When parsing the getpage and errorpage parameters, the process does not properly validate 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-18419.
