Authenticated command execution via unchecked volume parameter
Published Jun 15, 2026 · Updated Jun 15, 2026
Command injection in Tenda 5G03 V05.03.02.04 allows remote authenticated users to execute operating system commands via HTTP requests. The action_set_volume function in /usr/lib/lua/luci/controller/admin/telephony.lua uses the volume parameter in a command without validating shell metacharacters. Exploitation requires a valid sysauth session cookie and permits commands to run with the router service's privileges.
