CVE-2018-10562Dasan Routers — Command Injection on the Diagnostics Page

Dasan home routers run text from a diagnostics parameter as a system command and save the result where it runs again, so one request gives an attacker lasting control.

YOUR NEXT MOVE

Apply the vendor firmware update where one exists, and take the router management page off the wide-area side.
