Intel® NUC Kit with Infineon Trusted Platform Module
Certain Intel® NUC systems contain an Infineon Trusted Platform Module (TPM) that has an information disclosure vulnerability as described in CVE-2017-15361.
Recently, a research team developed advanced mathematical methods to exploit the characteristics of acceleration algorithms for prime number finding, which are common practice today for RSA key generation. For more information please reference the public advisory issued by Infineon: https://www.infineon.com/cms/en/product/promopages/rsa-update/?intc=0460001
Intel highly recommends users make sure they have the appropriate Windows operating system patches to work around this vulnerability. Please see the following advisory from Microsoft for details.
- Microsoft Advisory – https://portal.msrc.microsoft.com/en-us/security-guidance/advisory/ADV170012
For customers that require a firmware upgrade please contact Intel Customer Support at https://www.intel.com/content/www/us/en/support.html for assistance.
All newly manufactured Intel® NUC systems that contain the Infineon TPM have been updated with the updated firmware from Infineon. To verify your NUC’s firmware has been updated please check the SA number on the white sticker on the bottom of the NUC.
- The SA# on NUC7i5DN needs to be: J72865-504 or greater
- The SA# on NUC5i5MY needs to be: H47796-209 or greater
- The SA# on NUC5I3MY needs to be: J72865-504 or greater
Alternately you may manually check the TPM management snap-in (TPM.MSC) on each Windows 10 device to verify if the TPM firmware contains the vulnerability.
On devices running Windows 10 that have the October 2017 security update installed, in a CMD prompt, type "TPM.MSC" to open the TPM Management snap-in. Devices with affected TPM modules will display the following error message:
"The TPM is ready for use. The TPM firmware on this PC has a known security problem. Please contact your PC manufacturer to find out if an update is available. For more information please go to https://go.microsoft.com/fwlink/?linkid=852572."
