CVE-2023-24591 is a vulnerability identified in Intel(R) Binary Configuration Tool software versions prior to 3.4.4. The issue stems from an uncontrolled search path, which means that the software does not securely validate or restrict the directories it searches for executable or configuration files. This flaw can be exploited by an authenticated local user to escalate their privileges on the affected system. Specifically, because the search path is not properly controlled, an attacker with legitimate access could place malicious files in locations that the software searches, causing it to execute or load these files with elevated privileges. This type of vulnerability is particularly dangerous in environments where the Intel Binary Configuration Tool is used to manage or configure hardware or firmware components, as it could allow an attacker to gain higher-level access than intended, potentially compromising system integrity or confidentiality. The vulnerability requires local access and authentication, which limits remote exploitation but still poses a significant risk in multi-user systems or environments where users have limited privileges but share access to the same machine. No known exploits are currently reported in the wild, and no CVSS score has been assigned, but the medium severity rating reflects the potential impact of privilege escalation in sensitive environments.

For European organizations, the impact of this vulnerability could be substantial, especially in sectors relying heavily on Intel hardware and associated configuration tools, such as telecommunications, manufacturing, finance, and critical infrastructure. Privilege escalation vulnerabilities can lead to unauthorized access to sensitive data, disruption of system operations, and potential lateral movement within networks. In environments where multiple users share systems or where endpoint security is critical, exploitation could undermine trust in system integrity and lead to data breaches or operational downtime. Given the vulnerability requires local authenticated access, insider threats or compromised user accounts pose the most significant risk vectors. Additionally, organizations using automated deployment or configuration management tools that incorporate the Intel Binary Configuration Tool may inadvertently propagate the vulnerability across multiple systems, amplifying the potential impact.

To mitigate this vulnerability, European organizations should prioritize upgrading the Intel Binary Configuration Tool to version 3.4.4 or later, where the uncontrolled search path issue is addressed. Until patching is possible, organizations should implement strict access controls to limit local user privileges and restrict who can execute or modify the Intel Binary Configuration Tool. Monitoring and auditing of file system changes in directories commonly searched by the tool can help detect attempts to exploit the vulnerability. Employing application whitelisting and integrity verification mechanisms can prevent unauthorized or malicious files from being loaded. Additionally, organizations should review and harden local user account policies, enforce the principle of least privilege, and ensure that endpoint protection solutions are configured to detect suspicious local privilege escalation activities. For environments with shared systems, consider isolating critical configuration tools or restricting their usage to trusted administrators only.
