CVE-2024-38089
Improper Privilege Management (CWE-269)
Summary
Microsoft Defender for IoT Elevation of Privilege Vulnerability. This is a high-severity vulnerability with a CVSS base score of 9.9. It is a network-based attack vector with low attack complexity, requiring low privileges and no user interaction. The scope is changed, and it has high impact on confidentiality, integrity, and availability. This vulnerability affects Microsoft Defender for IoT versions prior to 24.1.4.
Impact
This vulnerability could allow an attacker with low privileges to elevate their privileges further in Microsoft Defender for IoT. The attack can be executed over the network without user interaction, potentially leading to a complete compromise of the targeted system's confidentiality, integrity, and availability. Given the changed scope, the impact could extend beyond the vulnerable component, affecting other parts of the system or network. This could result in unauthorized access to sensitive data, system manipulation, and potential disruption of IoT device management and security monitoring capabilities.
Exploitation
There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.
Patch
A patch is available. Microsoft has released an official fix for this vulnerability on July 9, 2024. The patch updates Microsoft Defender for IoT to version 24.1.4 or later, which addresses the vulnerability.
Mitigation
1. Apply the official patch released by Microsoft as soon as possible, updating Microsoft Defender for IoT to version 24.1.4 or later. 2. Implement network segmentation to limit the potential attack surface. 3. Monitor and audit privileged account activities. 4. Implement the principle of least privilege across your IoT environment. 5. Keep all Microsoft Defender for IoT instances updated to the latest version. 6. Implement strong authentication mechanisms for privileged accounts. 7. Regularly review and update access controls for Microsoft Defender for IoT.
