What to do

AI-suggested

  1. Immediately restrict access to the router’s management interface by limiting it to trusted internal networks and disabling remote management if not essential.
  2. Enforce strong, unique passwords for all administrative accounts and disable default credentials.
  3. Monitor router logs and network traffic for unusual commands or access patterns indicative of exploitation attempts.
  4. Implement network segmentation to isolate critical systems from devices running vulnerable firmware.
  5. Regularly audit and update device firmware; coordinate with TRENDnet for timely patch releases addressing this vulnerability.
  6. Employ multi-factor authentication for device management where supported to reduce risk from credential compromise.
  7. Use intrusion detection/prevention systems to detect anomalous HTTP requests targeting the vulnerable parameters.
  8. Educate network administrators about this vulnerability and the importance of secure device configuration.
  9. Consider replacing affected devices with models from vendors with stronger security track records if patches are delayed or unavailable.

Description

TRENDnet TEW-657BRM 1.00.1 has an authenticated remote OS command injection vulnerability in the setup.cgi binary, exploitable via the HTTP parameters "command", "todo", and "next_file," which allows an attacker to execute arbitrary commands with root privileges.
