CVE-2024-26021: Medium Vulnerability in Intel AMT and Standard Manageability

CVE-2024-26021 is classified as a medium severity vulnerability with a CVSS score of 4.6. This vulnerability allows improper initialization in the firmware for some Intel(R) AMT and Intel(R) Standard Manageability. Privileged users may potentially enable information disclosure through local access. With the potential for information leakage, organizations must understand the implications of this vulnerability.

The vulnerability was published on February 12, 2025, and is currently awaiting analysis. Organizations using affected Intel products should be aware of this vulnerability, as it poses a risk to their information security posture. The lack of known exploits at this time suggests a window for remediation before active attempts to leverage this vulnerability may be observed.

Organizations should prioritize patching immediately. By addressing this vulnerability, they can reduce the risk of exploitation and protect sensitive information from unauthorized access. As the situation evolves, continuous monitoring of the vulnerability landscape is essential.

In the context of this vulnerability, the attack vector is local, and the complexity is low, indicating that an attacker with high privileges could exploit it without needing user interaction. The implications for confidentiality are classified as low, while integrity and availability impacts are none.

Vulnerability Details

The official description of CVE-2024-26021 states that improper initialization in the firmware for some Intel(R) AMT and Intel(R) Standard Manageability may allow a privileged user to potentially enable information disclosure via local access. The CVSS 4.0 score of 4.6 indicates a medium severity level, while the CVSS 3.1 score of 2.3 indicates a low severity level. This discrepancy highlights the importance of understanding the context of vulnerability metrics.

The attack vector is local, and the attack complexity is low, which means that exploitation does not require special conditions. Privileges required are high, indicating that an attacker would need significant access to exploit this vulnerability. As for impacts, the confidentiality impact is low, and both integrity and availability impacts are none.

Technical Analysis

The root cause of CVE-2024-26021 lies in the improper initialization of firmware components associated with Intel's management technologies. This flaw allows privileged users to potentially access sensitive information that should be protected. The attack vector is strictly local, meaning that the attacker must have physical access to the device or system.

The attack complexity is low, which implies that exploitation can be achieved without requiring significant skill or resources. Since high privileges are required, this limits the potential pool of attackers to those who have already gained elevated access rights on the affected systems. User interaction is not needed, further facilitating potential exploitation.

The vulnerability's impact on confidentiality is low, suggesting that sensitive data could be exposed but not necessarily compromised in integrity or availability. Organizations should assess their environment to determine what specific information might be at risk should this vulnerability be exploited.

Risk & Impact Analysis

Risk to organizations includes unauthorized information disclosure, which could lead to data breaches or compliance issues. The blast radius potential is significant, especially for enterprises utilizing Intel AMT and Standard Manageability in critical operations. This vulnerability could facilitate further attacks if sensitive data is exposed.

Organizations should assess the urgency of addressing this vulnerability based on its CVSS score and the potential impact on their operations. Given the medium severity level, organizations should address it in their priority patch cycle. Continuous monitoring and risk assessment strategies should be implemented to manage the evolving threat landscape.

Affected Versions

Currently, there are no specific versions listed as affected. Organizations should consider all versions of Intel AMT and Intel Standard Manageability prior to any available vendor patch as potentially vulnerable.

Mitigation & Remediation

Organizations should monitor Intel's advisories for any patches or updates related to CVE-2024-26021. In the absence of a patch, applying configuration hardening and access controls can help mitigate the risk of exploitation. For continuous security testing, organizations can engage in continuous penetration testing to ensure that potential attack vectors are identified and remediated.

Detection Guidance

Monitoring for unusual access patterns or attempts to utilize Intel AMT functionalities could be indicative of an attempt to exploit this vulnerability. Organizations should implement logging for access attempts and review logs for any behavioral anomalies that could point to unauthorized access.

AppSecure Threat Intelligence Insight

The long-term significance of CVE-2024-26021 revolves around the increasing reliance on remote management technologies and their associated vulnerabilities. This vulnerability represents a potential trend where improper configurations lead to significant security risks. Security teams must learn from such vulnerabilities to enhance their defensive strategies.

Organizations are encouraged to develop a robust vulnerability management program that continuously assesses and addresses vulnerabilities as they arise. Additionally, security training for employees can help mitigate risks associated with human error.

Finally, leveraging threat intelligence services such as red teaming can provide insights into potential attack vectors and help organizations strengthen their defenses against vulnerabilities like CVE-2024-26021.

By proactively addressing vulnerabilities and fostering a culture of security awareness, organizations can significantly reduce the risk posed by vulnerabilities such as CVE-2024-26021.
