Detailsinfo

A vulnerability, which was classified as critical, was found in OnePlus 7 Pro. This affects an unknown code block of the component Trusted Execution Environment. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered on OnePlus 7 Pro devices before 10.0.3.GM21BA. The firmware was found to contain functionality that allows a privileged user (root) in the Rich Execution Environment (REE) to obtain bitmap images from the fingerprint sensor because of Leftover Debug Code. The issue is that the Trusted Application (TA) supports an extended number of commands beyond what is needed to implement a fingerprint authentication system compatible with Android. An attacker who is in the position to send commands to the TA (for example, the root user) is able to send a sequence of these commands that will result in the TA sending a raw fingerprint image to the REE. This means that the Trusted Execution Environment (TEE) no longer protects identifiable fingerprint data from the REE.

The weakness was published 04/14/2020. This vulnerability is uniquely identified as CVE-2020-7958 since 01/24/2020. 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 T1592 for this issue.

Upgrading to version 10.0.3.GM21BA eliminates this vulnerability.
