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.

A vulnerability was found in Daimler Mercedes Comand 17-13.0 50.12 (Vehicle Software). It has been declared as critical. This vulnerability affects an unknown code of the component Navigation Route Calculation. The manipulation with an unknown input leads to a data processing vulnerability. The CWE definition for the vulnerability is CWE-19. As an impact it is known to affect availability.

The bug was discovered 07/13/2018. The weakness was published 10/09/2018 by Marc Ruef with scip AG as VulDB 125080 as confirmed entry (VulDB). The advisory is shared for download at vuldb.com. The public release happened without coordination with the vendor. This vulnerability was named CVE-2018-18070 since 10/09/2018. The attack can be initiated remotely. A single authentication is needed for exploitation. Technical details are unknown but a private exploit is available. Defining or receiving a specific route might cause the Comand system to freeze and reboot after a few seconds. Whenever the system starts up again, it tries to re-calculate the route which will cause a boot loop. Under certain circumstances it is possible to quickly overwrite the malicious route to regain stability of the system.

A private exploit has been developed by Marc Ruef. It is declared as functional. The vulnerability was handled as a non-public zero-day exploit for at least 88 days. During that time the estimated underground price was around $0-$5k. The real existence of this vulnerability is still doubted at the moment. A local attacker might define a specific route. Or a remote attacker might use the Mercedes Me App to send a specific route.

Vendor was contacted for the first time on 08/06/2018 and assured to get back to the researcher. No further contact happened which is why a second request was sent on 09/11/2018. The vendor did not respond until 10/09/2018. In the meanwhile the vendor claims that an affected device will be reset after four hours of not using. It was not possible to confirm that.
