Advisory: Windows CryptoAPI certificate validation vulnerability
On January 14, 2020, Microsoft released security updates to address an elliptic-curve cryptography (ECC) certificate validation issue in the Windows CryptoAPI. This vulnerability applies to all versions of the Windows 10 operating system, client and server. While we have not observed an attack exploiting this vulnerability, we recommend that you apply this update to all of your Windows 10 devices with priority. Here is what you need to know:
  • If you are running a supported version of Windows 10 and have automatic updates enabled, you are automatically protected and do not need to take any further action.
  • If you are managing updates on behalf of your organization, you should download the latest updates from the Microsoft Security Update Guide and apply those updates to your Windows 10 devices and servers as soon as possible.
If you are running an unsupported version of Windows 10, we recommend that you upgrade to the current version of Windows 10 to benefit from the latest security protections. For more information about this vulnerability, see the Microsoft Security Guidance for CVE-2020-0601 and the Microsoft Security Response Center blog, January 2020 Security Updates: CVE-2020-0601.
