CVE-2026-78141Public exploitNetwork attack vector

Authenticated command execution via unchecked cmdinput

Published Aug 23, 2026 · Updated Aug 23, 2026

Command injection in Tenda CH22 firmware 1.0.0.1 allows remote authenticated users to execute commands through the cmdinput parameter. The formexeCommand handler at /goform/exeCommand passes attacker-controlled cmdinput data into command execution without adequate neutralization. A low-privilege authenticated network session is required, and execution occurs in the router's command-processing context.
