CVE-2024-47795 is a vulnerability identified in Intel's oneAPI DPC++/C++ Compiler software versions prior to 2025.0.0. The flaw arises from an uncontrolled search path mechanism within the compiler software, which can be exploited by an authenticated user with local access to escalate their privileges on the affected system. Specifically, the vulnerability allows a user with low privileges to manipulate the search path used by the compiler, potentially causing the execution of malicious code with elevated privileges. This type of vulnerability is commonly associated with improper handling of environment variables or file system paths that the software trusts implicitly without adequate validation or sanitization. The CVSS 4.0 base score of 5.4 (medium severity) reflects that exploitation requires local access, high attack complexity, and partial user interaction, but the impact on confidentiality, integrity, and availability is high. The vulnerability does not require network access, and no known exploits are currently reported in the wild. However, given the nature of the compiler software, which is often used in development environments and build pipelines, successful exploitation could allow an attacker to gain elevated privileges, potentially compromising the build environment and any software produced therein. This could lead to the insertion of malicious code into compiled binaries or unauthorized modification of build artifacts, undermining software supply chain integrity.

For European organizations, the impact of this vulnerability is significant particularly for those involved in software development, research, and industries relying on Intel's oneAPI DPC++/C++ Compiler for high-performance computing, AI, and heterogeneous computing workloads. Privilege escalation in development environments can lead to broader compromise of build systems, enabling attackers to inject malicious code into software products or gain unauthorized access to sensitive intellectual property. This risk is heightened in organizations with complex build pipelines and shared development environments. Additionally, compromised build environments can affect downstream customers and partners, amplifying the impact across supply chains. Given the medium severity and the requirement for local authenticated access, the threat is more relevant to insider threats or attackers who have already gained initial footholds within the network. The potential for high impact on confidentiality, integrity, and availability of software artifacts makes timely patching and mitigation critical to prevent supply chain attacks and maintain trust in software products.

To mitigate this vulnerability, European organizations should: 1) Immediately upgrade Intel oneAPI DPC++/C++ Compiler software to version 2025.0.0 or later where the vulnerability is addressed. 2) Restrict local access to build and development systems to trusted personnel only, enforcing strict access controls and monitoring for anomalous activities. 3) Implement environment hardening by validating and controlling environment variables and search paths used by compiler tools to prevent manipulation. 4) Employ application whitelisting and integrity verification mechanisms on build servers to detect unauthorized changes to compiler binaries or related files. 5) Use isolated build environments or containers to limit the impact of any potential compromise. 6) Monitor logs and audit trails for signs of privilege escalation attempts or unusual compiler behavior. 7) Educate developers and system administrators about the risks of local privilege escalation and the importance of secure build practices. These steps go beyond generic advice by focusing on controlling the local environment and build pipeline integrity, which are critical given the nature of this vulnerability.
