This allows an unauthenticated remote attacker to trigger a configuration backup and retrieve it in a form encrypted by a device-specific key. Triggering this function renders the router inoperable for a substantial period of time.\u00A0\n\n\n\nThis issue was\u00A0identified in firmware versions up to 4.2.17.
