The network enabled distribution of Kura before 2.1.0 takes control over the devices firewall setup but does not allow IPv6 firewall rules to be configured. Still the Equinox console port 5002 is left open, allowing to log into Kura without any user credentials over unencrypted telnet and executing commands using the Equinox exec command. As the process is running as root full control over the device can be acquired. IPv6 is also left in auto-configuration mode, accepting router advertisements automatically and assigns a MAC address based IPv6 address.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
