CVE-2017-6079: Ribboncommunications Edgemarc Firmware: Command injection
CVE-2017-6079 is rated critical with a CVSS v3.1 base score of 9.8 and NVD lists Ribboncommunications Edgemarc Firmware as the affected product. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.
Vulnerability description
The HTTP web-management application on Edgewater Networks Edgemarc appliances has a hidden page that allows for user-defined commands such as specific iptables routes, etc., to be set. You can use this page as a web shell essentially to execute commands, though you get no feedback client-side from the web application: if the command is valid, it executes. An example is the wget command. The page that allows this has been confirmed in firmware as old as 2006.
