CVE-2024-24582 is a vulnerability identified in the XmlCli feature of UEFI firmware on certain Intel processors. The root cause is improper input validation, which can be exploited by a user who already has privileged local access to escalate their privileges further. The UEFI firmware is a critical low-level component responsible for initializing hardware and bootstrapping the operating system, and vulnerabilities here can have severe implications. The attack vector is local, requiring the attacker to have high privileges initially, but no user interaction is needed to exploit the flaw. The vulnerability affects confidentiality, integrity, and availability at a high level, meaning an attacker could potentially gain unauthorized access to sensitive data, modify system configurations, or disrupt system operations. Although no known exploits are currently reported in the wild, the high CVSS score of 8.7 reflects the potential severity if exploited. The vulnerability affects multiple versions of Intel processors, though specific affected models are detailed in Intel's advisories. The complexity of exploitation is high due to the need for privileged access and the requirement for local presence, but the impact on compromised systems could be critical. This vulnerability highlights the importance of securing firmware components and controlling privileged access on systems using Intel hardware.

For European organizations, the impact of CVE-2024-24582 could be significant, especially in sectors relying heavily on Intel processors such as finance, government, telecommunications, and critical infrastructure. Successful exploitation could allow attackers with existing privileged access to gain even higher privileges, potentially leading to full system compromise, unauthorized data access, or disruption of critical services. This could result in data breaches, operational downtime, and damage to organizational reputation. Given the firmware-level nature of the vulnerability, remediation may require firmware updates that can be complex to deploy in large environments. Additionally, the vulnerability could be leveraged in multi-stage attacks where initial access is gained through other means, making it a critical risk in defense-in-depth strategies. European organizations with stringent data protection regulations (e.g., GDPR) must consider the compliance implications of such a vulnerability being exploited. The lack of public exploits currently reduces immediate risk but does not eliminate the threat, especially from advanced persistent threats (APTs) targeting high-value European assets.

1. Monitor Intel's official advisories closely and apply firmware updates or patches as soon as they become available to address CVE-2024-24582. 2. Restrict privileged local access to systems with affected Intel processors to trusted personnel only, employing strict access controls and auditing. 3. Implement robust endpoint detection and response (EDR) solutions capable of detecting unusual privilege escalation attempts or firmware tampering. 4. Employ hardware-based security features such as Intel Boot Guard and Trusted Platform Module (TPM) to enhance firmware integrity verification. 5. Conduct regular security assessments and penetration tests focusing on firmware and local privilege escalation vectors. 6. Maintain an inventory of affected hardware to prioritize patching and risk management efforts. 7. Educate system administrators and security teams about the risks associated with firmware vulnerabilities and the importance of timely patching. 8. Where possible, isolate critical systems to limit the impact of potential local privilege escalations. 9. Use multi-factor authentication and strong credential management to reduce the risk of initial privileged access compromise.
