CVE-2024-28047

Overview

CVE-2024-28047 describes an improper input validation vulnerability within the UEFI firmware of certain Intel processors. The root cause lies in insufficient validation of inputs passed to the firmware, potentially allowing a privileged user to trigger unintended behavior that exposes sensitive data [1].

Exploitation

Exploitation requires local access and elevated privileges on the target system. An attacker with such access could craft specific inputs to the vulnerable UEFI component, bypassing the intended security checks that normally restrict access to protected firmware data [1].

Impact

Successful exploitation leads to information disclosure, where the attacker may read confidential data stored or processed within the UEFI environment. This could include secrets such as cryptographic keys, configuration details, or other sensitive parameters that are not meant to be accessible to the operating system or user-level code [1].

Mitigation

Intel has released firmware updates to address this vulnerability. Users should apply the latest UEFI firmware patches from their system or motherboard vendor. No workarounds are documented; upgrading to a patched firmware version is the recommended remediation [1].
