Technical details
A NULL pointer dereference vulnerability exists in the UPnP daemon on TP-Link TL-WR841N v14 when processing SOAP (Simple Object Access Protocol) action requests. An unauthenticated remote attacker on the network can send a specially crafted SOAP request with malformed XML content to trigger the vulnerability, causing the UPnP daemon process to dereference a NULL pointer and terminate abnormally. The attack requires network access to the router but no authentication. Successful exploitation results in denial-of-service (DoS) affecting UPnP functionality until the service is restarted or the device is rebooted. No patch information is currently available.
