Summary
A vulnerability has been identified in SIMATIC IPC BX-21A (All versions < V31.01.13), SIMATIC IPC RW-543A (All versions < V1.1.4), SIMATIC IPC227G / IPC277G / IPC277G PRO / IPC327G / IPC377G (All versions < V28.01.15). A BIOS vendor test key is present in the UEFI Secure Boot key database. This could allow a local attacker with physical or administrative access to the device to boot an operating system or UEFI application signed with that test key, bypassing UEFI Secure Boot protections even when Secure Boot is enabled, potentially leading to a full loss of confidentiality, integrity, and availability of the device.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
