CVE-2026-78063Public exploitNetwork attack vector

Authenticated OS command execution via editNameMit handling

Published Aug 23, 2026 · Updated Aug 23, 2026

Command injection in Tenda CH22 Firmware 1.0.0.1 allows remote authenticated users to execute operating-system commands. The formeditFileName handler at /goform/editFileName incorporates the editNameMit parameter into a shell command without neutralizing command separators. Low-privileged network-management access is required, and exploitation can read or alter data and interrupt service under the firmware process's privileges.
