Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
D-Link DAP-1360 webproc COMM_MakeCustomMsg 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. 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-18454.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-121

Data overflows a fixed-size buffer allocated on the stack, overwriting adjacent stack memory — including saved return addresses — which is the classic route to redirecting execution into attacker-supplied code. Crafted input is all it takes. Remediation is strict length checks, safe bounded string and memory functions, and modern stack-protection mitigations.

Recommended fix High confidence

DAP-1360: 6.15eub01; DAP-2020: 1.03rc004

  1. 1. Visit the official D-Link support announcement at https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10324 to obtain the patched firmware
  2. 2. Identify your router model (DAP-1360 or DAP-2020) and confirm current firmware version
  3. 3. Download the appropriate patched firmware: DAP-1360 version 6.15eub01 or later, DAP-2020 version 1.03rc004 or later
  4. 4. Access the router's web management interface by navigating to its IP address
  5. 5. Locate the firmware upgrade section (usually under System or Management settings)
  6. 6. Upload the new firmware file and apply the upgrade; do not interrupt power during this process
  7. 7. After the router reboots, verify the new firmware version is installed
Caveat Standard firmware upgrade risks apply - ensure stable power and consider backing up configuration
