CVE-2025-33178 is a vulnerability classified under CWE-94 (Improper Control of Generation of Code) found in the NVIDIA NeMo Framework, specifically within the bert services component. This flaw allows an attacker to inject malicious code by crafting specially designed input data that the framework improperly processes, leading to arbitrary code execution. The vulnerability affects all versions of the NeMo Framework prior to 2.5.0 across all platforms. Exploitation requires local access with low privileges (PR:L), no user interaction (UI:N), and low attack complexity (AC:L), making it relatively straightforward for an attacker who can supply input to the bert services component. Successful exploitation can result in full compromise of the affected system, including execution of arbitrary code, escalation of privileges beyond the initial access level, unauthorized disclosure of sensitive information, and tampering with data integrity. The CVSS v3.1 base score is 7.8, reflecting high severity with high impact on confidentiality, integrity, and availability. No public exploits have been reported yet, but the vulnerability's nature and ease of exploitation make it a critical risk for environments using the NeMo Framework for AI and natural language processing tasks. The lack of available patches at the time of publication necessitates immediate attention to mitigation strategies.

For European organizations, the impact of CVE-2025-33178 can be substantial, particularly for those leveraging NVIDIA NeMo Framework in AI research, development, and deployment. Successful exploitation could lead to unauthorized code execution within critical AI workloads, potentially compromising intellectual property, sensitive data, and operational integrity. This could disrupt AI-driven services, cause data breaches, and lead to loss of trust or regulatory penalties under GDPR due to data exposure. Organizations in sectors such as automotive (where NVIDIA AI solutions are prevalent), telecommunications, finance, and academia are at heightened risk. The ability to escalate privileges means attackers could gain broader access to internal networks, increasing the risk of lateral movement and further compromise. The vulnerability's local attack vector limits remote exploitation but does not eliminate risk in environments where multiple users have access or where attackers can gain initial footholds through other means. Overall, the threat could undermine the confidentiality, integrity, and availability of AI systems critical to European digital infrastructure and innovation.

1. Upgrade the NVIDIA NeMo Framework to version 2.5.0 or later as soon as it becomes available to ensure the vulnerability is patched. 2. Until patching is possible, restrict access to the bert services component by enforcing strict access controls and limiting usage to trusted users only. 3. Implement rigorous input validation and sanitization on all data fed into the bert services to prevent malicious code injection. 4. Monitor logs and system behavior for unusual activity indicative of exploitation attempts, such as unexpected code execution or privilege escalations. 5. Employ application whitelisting and runtime application self-protection (RASP) techniques to detect and block unauthorized code execution. 6. Conduct regular security audits and penetration testing focused on AI frameworks and their components. 7. Educate developers and system administrators about secure coding practices and the risks of code injection vulnerabilities in AI frameworks. 8. Isolate AI workloads in segmented network environments to contain potential breaches. 9. Maintain up-to-date backups of critical AI models and data to enable recovery in case of tampering or data loss.
