Description
A NULL
pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP action requests. A specially crafted SOAP action request containing unexpected XML content may cause the UPnP daemon to terminate unexpectedly.
Successful exploitation may result in a denial-of-service condition affecting UPnP functionality until the service is restarted or the device is rebooted.
