CVE-2025-24327 is a vulnerability in Intel Rapid Storage Technology (RST) Application prior to version 20.0.1021 that allows an escalation of privilege due to insecure inherited permissions within Ring 3 user applications. The flaw permits an unprivileged, authenticated user to execute local code with elevated privileges, potentially compromising the confidentiality, integrity, and availability of the affected system. The attack complexity is high, requiring local access and active user interaction, which limits remote exploitation. The vulnerability stems from improper permission inheritance mechanisms in the RST application, which is commonly used for managing storage devices and RAID configurations on Intel-based systems. While the vulnerability affects local system security, it does not extend to network-level impacts or broader system confidentiality beyond the compromised host. The CVSS 4.0 base score is 5.4 (medium), reflecting the balance between the high impact on the local system and the high complexity and interaction requirements for exploitation. No public exploits are known, but the risk remains for targeted attacks, especially in environments where users have local access but limited privileges. Intel has reserved and published this vulnerability in 2025 and recommends updating to fixed versions to mitigate the risk.

For European organizations, this vulnerability poses a significant risk to endpoint security, particularly on systems running Intel RST versions before 20.0.1021. Successful exploitation could allow attackers with local access to escalate privileges, potentially leading to unauthorized data access, manipulation, or disruption of storage management functions. This could impact critical business operations, especially in sectors relying heavily on data integrity and availability such as finance, healthcare, and manufacturing. The requirement for local access and user interaction reduces the likelihood of widespread remote attacks but increases the risk from insider threats or compromised user accounts. Organizations with extensive Intel hardware deployments and those using Intel RST for RAID or storage management are particularly vulnerable. The medium severity rating suggests that while the threat is not immediately critical, it warrants timely remediation to prevent potential exploitation in targeted attacks.

1. Immediately update Intel Rapid Storage Technology Application to version 20.0.1021 or later, where the vulnerability is patched. 2. Implement strict local user permission controls to limit the ability of low-privileged users to execute or modify RST application components. 3. Employ application whitelisting and endpoint protection solutions to detect and block unauthorized code execution attempts related to RST. 4. Conduct regular audits of local user accounts and permissions to identify and remediate excessive privileges. 5. Educate users on the risks of executing untrusted code and the importance of avoiding suspicious interactions that could trigger exploitation. 6. Monitor system logs for unusual activities related to Intel RST processes or privilege escalations. 7. In sensitive environments, consider isolating systems running Intel RST to reduce the risk of insider threats. 8. Coordinate with Intel support and subscribe to security advisories for timely updates and patches.
