Overview

CVE-2017-7649 is a critical-severity vulnerability. It was published on September 11, 2017 and has a CVSS 3.0 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.0 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The network enabled distribution of Kura before 2.1.0 takes control over the device's 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
