5. Protocol & File Format Findings

• Discovery: UDP broadcasts to 255.255.255.255:port and SSDP; packets contain device model and LAN IP.
• Config files: XML-based structures with cleartext credentials in some fields; sometimes base64-encoded but reversible.
• Firmware upload: HTTP POST multipart/form-data to device or via firmware server URL; server-side validation often limited.
• TR-069: Exposes RPC methods; ZCU can provision ACS URL and credentials.

. You will need the device's Serial Number and MAC address (found on the physical sticker). python examples/auto.py --serial "ZTEGXXXXXXXX" "xx:xx:xx:xx:xx" config.bin config.xml ``` Use code with caution. Copied to clipboard 4. Modifying and Re-encoding config.xml in a text editor to view or change settings (like the password). To save changes back to the router, encode the file again: python3 examples/encode.py config.xml config_new.bin ``` Use code with caution. Copied to clipboard config_new.bin back to your router via the web management interface. Important Notes Discovery: UDP broadcasts to 255
