Huawei FusionSphere OpenStack signature verification

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 Huawei FusionSphere OpenStack (Cloud Software) (the affected version is unknown). It has been rated as critical. This issue affects an unknown code. The manipulation with an unknown input leads to a signature verification vulnerability. Using CWE to declare the problem leads to CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

FusionSphere OpenStack V100R006C00SPC102(NFV)has an improper verification of cryptographic signature vulnerability. The software does not verify the cryptographic signature. An attacker with high privilege may exploit this vulnerability to inject malicious software.

The bug was discovered 11/16/2017. The weakness was published 11/22/2017 (Website). The advisory is shared at The identification of this vulnerability is CVE-2017-8190 since 04/25/2017. The exploitation is known to be easy. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.
