Executive Technical Summary

An issue was discovered on Dasan GPON home routers. Command Injection can occur via the dest_host parameter in a diag_action=ping request to a GponForm/diag_Form URI. Because the router saves ping results in /tmp and transmits them to the user when the user revisits /diag.html, it's quite simple to execute commands and retrieve their output.

Practical Defensive Validation (Authorized Only)

1. Use only isolated environments and systems you own or are explicitly authorized to test.
2. Snapshot infrastructure before validation and preserve baseline logs (EDR, SIEM, OS, app).
3. Deploy dasannetworks / gpon router firmware with synthetic data and validate strict server-side input validation and parameterization.
4. Replay safe payload patterns through WAF/IDS tuning pipelines to reduce false negatives.
5. Correlate request IDs with app/database logs to improve root-cause analysis speed.
