CVE-2018-10562 KEV EXPLOIT
9.8
CRITICAL · CVSS 3.1 · EPSS 99.9% (pctl 100)
Patch first
On CISA KEV — known exploited in the wild, due 2022-04-21.
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.
