The device does not adequately verify the credentials in the HTTP Authorization field when requests are made to the \/upload endpoint. Then the upload.cgi binary will use the contents of the HTTP Cookie field as part of a curl request aimed at an internal endpoint. The curl request is executed using popen and allows the attacker to inject commands via the Cookie field. A remote and unauthenticated attacker using this module is able to achieve code execution as www-data.
