At a Glance

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.

Recommended Actions

Prioritize immediate patching and validate internet-facing exposure. Monitor for matching exploitation attempts in your environment.
Review sensor telemetry for request paths, attacker IPs, and payload patterns that may inform detection and exposure validation.
Check enrichment artifacts for scanner coverage and available PoCs before rolling remediation validation.
Use the Pro API to automate enrichment, telemetry, and workflow delivery for VM, SOC, and CTI pipelines.
