| Description | ddns_wan_list_show.cgi fetches configured DDNS records and appends both user_idN and passwordN directly into the JSON response. The web UI then writes those values back into the DDNS form, so any authenticated web client can recover provider credentials instead of a masked placeholder. An ordinary POST with noneed=noneed is sufficient: the handler treats stored DDNS secrets as readable configuration rather than write-only values, exposing reusable provider usernames and passwords to anyone with a management session. |
