CVE-2022-28697 is a vulnerability identified in the firmware of Intel(R) Active Management Technology (AMT) and Intel(R) Standard Manageability. The flaw arises from improper access control mechanisms within the firmware, which may allow an unauthenticated attacker with physical access to the affected system to escalate privileges. Specifically, the vulnerability enables an attacker to bypass security restrictions and gain elevated privileges without requiring authentication or user interaction. Intel AMT and Standard Manageability are components embedded in many Intel chipsets designed to provide remote management capabilities, including out-of-band management, hardware-level monitoring, and system provisioning. These features are widely used in enterprise environments to manage large fleets of computers remotely. The CVSS 3.1 base score of 6.8 classifies this vulnerability as medium severity, reflecting the fact that exploitation requires physical access (Attack Vector: Physical) but has low attack complexity and no need for privileges or user interaction. The impact on confidentiality, integrity, and availability is high, meaning that successful exploitation could lead to full system compromise, unauthorized data access, and disruption of system operations. No known exploits in the wild have been reported to date, but the presence of this vulnerability in firmware means that remediation typically requires firmware updates or hardware replacement, which can be operationally challenging. Given the nature of Intel AMT and Standard Manageability, this vulnerability primarily affects enterprise and organizational environments where such management technologies are deployed.

For European organizations, the impact of CVE-2022-28697 can be significant, especially for sectors relying heavily on Intel-based hardware with AMT capabilities, such as government agencies, financial institutions, healthcare providers, and large enterprises. The vulnerability allows an attacker with physical access to bypass security controls and escalate privileges, potentially leading to unauthorized access to sensitive data, disruption of critical services, and compromise of system integrity. This risk is heightened in environments where physical security controls may be insufficient or where devices are deployed in less secure locations. Additionally, the ability to escalate privileges without authentication could facilitate further lateral movement within networks once initial access is gained. The requirement for physical access somewhat limits remote exploitation but does not eliminate risk, as insider threats or attackers with temporary physical access could exploit this flaw. The operational impact includes the need for firmware updates or hardware replacements, which may be complex and costly for organizations with large device inventories. Failure to address this vulnerability could lead to regulatory compliance issues under frameworks like GDPR if data breaches occur as a result.

To mitigate CVE-2022-28697 effectively, European organizations should take the following specific actions: 1) Conduct an inventory of all Intel-based systems to identify devices with Intel AMT and Standard Manageability enabled. 2) Apply the latest firmware updates provided by Intel or device manufacturers that address this vulnerability as soon as they become available. 3) Implement strict physical security controls to prevent unauthorized physical access to devices, including secure facilities, locked server rooms, and tamper-evident seals. 4) Disable Intel AMT and Standard Manageability features on devices where remote management is not required, reducing the attack surface. 5) Monitor and audit physical access logs and device management activities to detect any unauthorized attempts to access or modify firmware settings. 6) Train IT and security staff on the risks associated with firmware vulnerabilities and the importance of timely patching and physical security. 7) Consider deploying endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of privilege escalation or firmware tampering. These measures go beyond generic advice by focusing on firmware-specific patching, physical security enhancements, and operational controls tailored to the nature of this vulnerability.
