Technical details
A command injection vulnerability exists in the Tenda 5G03 router within the Lua-based web management interface. Specifically, the 'action_set_rat_mode' function in '/usr/lib/lua/luci/controller/admin/telephony.lua' fails to properly sanitize the 'ratMode' parameter before passing it to a system shell via 'string.format' and 'mipc_wan_cli'. An authenticated attacker can exploit this by injecting shell metacharacters (e.g., quotes and semicolons) into the 'ratMode' field of a POST request to the '/cgi-bin/luci/admin/telephony/trigger_set_nw_rat' endpoint. Successful exploitation allows for arbitrary command execution with the privileges of the web service, typically root on such embedded devices.
