HPSBHF03576 rev. 3 - Intel AMT MEBx Bypass
Notice: The information in this security bulletin should be acted upon as soon as possible.
Release date : 18-Jan-2018
Last updated : 05-Jul-2018
Un-provisioned Intel® vPro™ platforms containing Intel® Active Management Technology (Intel® AMT) are vulnerable to unauthorized local provisioning via physical access. The attack involves accessing the MEBx (
Management Engine BIOS Extensions) menu via the default MEBx password. When the device is shipped or if the coin cell battery is removed, MEBx uses the default password.
Note that Intel® AMT must be enabled to have the capability of being provisioned.
For non-vPro™ SKUs, Intel® AMT is not supported and the system is not affected.
PSR-2017-0115
See the RESOLUTION section for impacted products.

This bulletin will be updated; check back frequently for updates.
The following platforms have an updated BIOS that protects the MEBx menu when the BIOS Admin password is created. Access to the MEBx menu will require a BIOS Admin password when the BIOS Admin is created. HP strongly recommends customers to setup a BIOS admin password.
MITIGATION
For platforms without an updated BIOS, HP strongly urges customers to do the following:
-
Change the MEBx password from the default setting.
-
Set BIOS Admin password.
-
Add power-on password to BIOS via F10. Adding this password will subsequently require physical presence from the user before system completes boot. It will also prevent the attacker from accessing MEBx.
-
Check USB Provisioning in F10 to ensure it is disabled in the system BIOS.
