Description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of D-Link DCS-960L v1.07.102. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default.

An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-8458.
