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 Lenovo PC (affected version unknown). It has been declared as critical. This vulnerability affects an unknown functionality of the component Backdoor. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was presented 07/26/2013 as Spy agencies ban Lenovo PCs on security concerns as not defined news (Website). The advisory is shared for download at afr.com. The public release happened without coordination with the vendor. The news contains:

Lenovo, which is headquartered in Beijing, acquired IBM’s PC business in 2005. IBM continues to sell servers and mainframes that are accredited for secret and top-secret networks. A Defence spokesman said Lenovo had never sought accreditation.

The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a private exploit is available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 03/19/2019). This vulnerability has a historic impact due to its background and reception. The advisory points out:

Computers manufactured by the world’s biggest personal computer maker, Lenovo, have been banned from the “secret” and ‘‘top secret” ­networks of the intelligence and defence services of Australia, the US, Britain, Canada, and New Zealand, because of concerns they are vulnerable to being hacked. (…) The ban was introduced in the mid-2000s after intensive laboratory testing of its equipment allegedly documented “back-door” hardware and “firmware” vulnerabilities in Lenovo chips.

It is declared as functional. The real existence of this vulnerability is still doubted at the moment.

The problem might be mitigated by replacing the product with as an alternative. The news contains the following remark:

In 2006 it was disclosed that the US State Department had decided not to use 16,000 new Lenovo computers on classified networks because of security concerns. The change in procurement policy was attributed to anti-China trade sentiment after ­Lenovo’s acquisition of IBM’s PC business. Some experts argue that blocking specific companies from classified networks is not a panacea for security threats given the global nature of supply chains. Many western vendors have semiconductor fabrication plants, or “foundries”, based in China, which exposes them to the risk of interference.
