CVE-2025-65202Public exploit

Root command execution via setup.cgi parameter concatenation

Published Nov 26, 2025 · Updated Nov 28, 2025

OS command injection in TRENDnet TEW-657BRM 1.00.1 allows remote authenticated users to execute arbitrary commands as root via HTTP requests. The setup.cgi binary concatenates the command parameter into a shell command when todo and next_file select the system-command operation, without neutralizing shell syntax. An authenticated session and network access to the management interface are required; successful exploitation grants complete control of the device.
