CVE-2018-10562 | BDVDB-2026-100385 Detail
DasanGigabit Passive Optical Network (GPON) Routers
Description#
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.
