Impact

A buffer overflow exists in the /tggl.asp endpoint of D‑Link DI‑8003 firmware 16.07.26A1, which can be triggered by sending input that exceeds the expected size. Because the endpoint fails to validate input, an attacker can overwrite the stack and execute arbitrary code. This allows full remote code execution on the device, compromising confidentiality, integrity, and availability. The weakness is classified as CWE‑120.

Affected Systems

The affected product is the D‑Link DI‑8003 wireless router running firmware version 16.07.26A1. No other versions are explicitly listed, so the risk applies only to devices with this firmware.

Risk and Exploitability

The CVSS base score of 7.5 indicates high severity, yet the EPSS score is below 1%, suggesting that real‑world exploitation is currently rare. The vulnerability is not yet listed in the CISA KEV catalog. The likely attack vector is through the web interface exposed by the device, accessible to attackers who can reach the router over the network. Successful exploitation would grant the attacker full control of the device.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the device firmware to the latest version that addresses the buffer overflow.
  • If no update is available, disable the /tggl.asp endpoint or restrict web‑access to trusted IP addresses.
  • Verify that the device is isolated from untrusted networks and consider applying network segmentation.
  • Monitor network traffic for unusual POST requests to /tggl.asp.
  • Refer to D‑Link's security bulletin for further guidance.
