Impact

A flaw in TRENDnet Router 1.1.02b01’s /cgi-bin/ping.cgi allows manipulation of the argument wan_type, resulting in command injection. Attackers can execute arbitrary commands. The vulnerability may be used to compromise the device.

Affected Systems

TRENDnet routers running firmware version 1.1.02b01. The issue resides in an unknown function within the ping.cgi CGI script, part of the router’s web interface.

Risk and Exploitability

The CVSS base score of 5.3 indicates a medium severity. The EPSS score of 1% indicates a low but non‑zero exploitation probability, and the vulnerability is not listed in the KEV catalog, which limits certainty about current exploitation rates. However, the published proof‑of‑concept code shows that a remote attacker can launch the exploit by sending a crafted HTTP to /cgi-bin/ping.cgi with a malicious wan_type value. The description does not specify whether authentication is required, but the attack can be performed over the Internet, making it a substantial risk to exposed devices.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the router firmware to a version that removes the vulnerable ping.cgi implementation or patches the command injection flaw
  • If an immediate firmware update is not available, block external access to the /cgi-bin/ping.cgi endpoint using the router’s firewall or an external perimeter firewall, limiting management traffic to the internal network only
  • Disable or restrict remote web management services altogether, or place the router behind a DMZ with strict access controls to reduce exposure
