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.

Laut BMW sind weltweit 2,2 Millionen, in Deutschland etwa 423.000 Autos der Marken BMW, Mini und Rolls Royce betroffen, die seit 2010 mit "ConnectedDrive" ausgeliefert wurden. BMW will das Problem nach eigenen Angaben bis zum 31. Januar 2015 durch Einschalten einer Verschlüsselung der Kommunikation mit dem Fahrzeug beseitigt haben.

Upgrading eliminates this vulnerability. A possible mitigation has been published 1 days after the disclosure of the vulnerability. The article contains the following remark:

Für das Schließen der Sicherheitslücke sind kein Werkstattbesuch und kein Teiletausch erforderlich, da das Einschalten der Verschlüsselung seit dem 8. Dezember 2014 im Hintergrund über Mobilfunk erfolgt. Die BMW-Halter können nicht selbst erkennen, ob ihre Fahrzeuge bereits bearbeitet wurden. Wer hierzu Gewissheit haben will (weil das Auto über einen längeren Zeitraum keinen Mobilfunkempfang hatte, etwa in einer Tiefgarage oder wegen abgeklemmter Batterie), sollte sich an die BMW-Hotline unter Tel. 089/125016010 wenden.
