Ein entfernter, anonymer Angreifer kann eine Schwachstelle in TianoCore EDK2 ausnutzen, um beliebigen Programmcode mit Ring-0-Rechten auszuführen oder einen Denial-of-Service-Zustand zu verursachen.
Editorial Analysis
Enterprises using PXE-based provisioning could face firmware-level compromise, undermining Secure Boot guarantees and enabling persistent, hard-to-detect implants.
Assess PXE boot exposure in your environment, update EDK2 firmware where possible, and restrict PXE to isolated provisioning VLANs.
A firmware-level vulnerability in network boot components could allow deep system compromise during device provisioning.
