Huawei Mate 20/Mate 20 X/Mate 20 RS/Honor Magic2 path traversal

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.

The affected component should be upgraded.

Detailsinfo

A vulnerability classified as critical has been found in Huawei Mate 20, Mate 20 X, Mate 20 RS and Honor Magic2 (Smartphone Operating System) (the affected version unknown). This affects an unknown part. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

HUAWEI Mate 20 versions earlier than 10.1.0.160(C00E160R3P8), HUAWEI Mate 20 X versions earlier than 10.1.0.135(C00E135R2P8), HUAWEI Mate 20 RS versions earlier than 10.1.0.160(C786E160R3P8), and Honor Magic2 smartphones versions earlier than 10.1.0.160(C00E160R2P11) have a path traversal vulnerability. The system does not sufficiently validate certain pathname from certain process, successful exploit could allow the attacker write files to a crafted path.

The weakness was published 07/17/2020 (Website). The advisory is shared at huawei.com. This vulnerability is uniquely identified as CVE-2020-9252 since 02/18/2020. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

Upgrading eliminates this vulnerability.
