5.1 · MEDIUMOverview
CVE-2020-11005 is a medium-severity vulnerability affecting windowshello_project windowshello. It was published on April 14, 2020 and has a CVSS 3.1 base score of 5.1 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.1, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The WindowsHello open source library (NuGet HaemmerElectronics.SeppPenner.WindowsHello), before version 1.0.4, has a vulnerability where encrypted data could potentially be decrypted without needing authentication. If the library is used to encrypt text and write the output to a txt file, another executable could be able to decrypt the text using the static method NCryptDecrypt from this same library without the need to use Windows Hello Authentication again. This has been patched in version 1.0.4.
Remediation
Check the references section for vendor advisories and patches from windowshello_project. Update windowshello to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
