| Título | Tozed Kangwei ZLT X300 6.01.3 Command Injection |
|---|
| Descrição | The Tozed ZLT X300 5G CPE router contains a critical OS command injection vulnerability in its TR-069/CWMP client daemon (netcwmpd). The IPPingDiagnostics handler
(process_ping function at 0x463A14) passes the Host parameter from TR-069 SetParameterValues directly into a sprintf format string at 0x463E6C that builds a shell
command. The command is executed via system_by_root() as root through the service_shell dispatcher chain (sub_5BA8C4 → sub_5BC23C → sub_5BBC88). No input validation is
performed on the Host parameter.
