CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in LIFX Light Bulb (affected version not known). It has been classified as problematic. Affected is some unknown functionality of the component Mesh Network Handler. The manipulation with an unknown input leads to a missing encryption vulnerability. CWE is classifying the issue as CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. This is going to have an impact on confidentiality, and integrity.

The weakness was published 07/04/2014 as Hacking into Internet Connected Light Bulbs as not defined blog post (Website). The advisory is shared for download at contextis.com. The public release happened without coordination with the vendor. The blog post contains:

In the event of the master bulb being turned off or disconnected from the network, one of the remaining bulbs elects to take its position as the master and connects to the WiFi network ready to relay commands to any further remaining bulbs.

The attack can only be initiated within the local network. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 04/11/2019). The MITRE ATT&CK project declares the attack technique as T1600. This vulnerability has a historic impact due to its background and reception. The advisory points out:

As can be observed in the packet capture above, the WiFi details, including credentials, were transferred as an encrypted binary blob. Further analysis of the on-boarding process identified that we could inject packets into the mesh network to request the WiFi details without the master bulb first beaconing for new bulbs.

Upgrading eliminates this vulnerability. The upgrade is hosted for download at updates.lifx.co.
