A vulnerability exists in UEFI implementations that use a hard-coded software-based Platform Key (PK). An attacker in possession of the corresponding PK private key can sign arbitrary UEFI executables or firmware components, causing them to be trusted by affected systems and potentially bypassing UEFI Secure Boot trust validation.

A vulnerability related to the use an insecure Platform Key (PK) has been discovered. An attacker with the compromised PK private key can create malicious UEFI software that is signed with a trusted key that has been compromised.

PRIMERGY is an IA server provided by Fsas Technologies Inc. PRIMERGY contains a vulnerability where Secure Boot function is bypassed. This is due to a vulnerability called "PKFail" (CVE-2024-8105), which was publicly disclosed by Binarly. Fsas Technologies Inc. reported this vulnerability to JPCERT/CC to notify users of its solution through JVN. JPCERT/CC and Fsas Technologies Inc. coordinated under the Information Security Early Warning Partnership.

A vulnerability in the use of hard-coded Platform Keys (PK) within the UEFI framework, known as PKfail, has been discovered in several Pepperl+Fuchs devices.
