CVE-2025-33204 identifies a critical code injection vulnerability (CWE-94) within the NVIDIA NeMo Framework, specifically targeting its natural language processing (NLP) and large language model (LLM) components. The flaw stems from improper control over code generation, allowing attackers to craft malicious input data that the framework processes insecurely, leading to arbitrary code execution. This vulnerability affects all NeMo versions prior to 2.5.1 across all supported platforms. The attack vector requires local access with low privileges (AV:L), low attack complexity (AC:L), and privileges (PR:L), but no user interaction (UI:N). Successful exploitation can escalate privileges, disclose sensitive information, and tamper with data, impacting confidentiality, integrity, and availability. Although no exploits have been observed in the wild, the high CVSS score (7.8) reflects the serious risk posed. The vulnerability is particularly concerning for environments running AI workloads where NeMo is integrated, as it could compromise AI model integrity and data confidentiality. The absence of patch links suggests the fix is likely included in version 2.5.1 or later, emphasizing the need for timely updates. Organizations leveraging NVIDIA NeMo in production or research should prioritize vulnerability assessment and remediation to prevent potential exploitation.

For European organizations, the impact of CVE-2025-33204 is significant due to the increasing adoption of AI and NLP technologies in sectors such as finance, healthcare, automotive, and critical infrastructure. Exploitation could lead to unauthorized code execution within AI processing environments, potentially compromising sensitive data, intellectual property, and AI model integrity. Privilege escalation could allow attackers to gain broader system control, facilitating lateral movement and further attacks. Data tampering risks undermine trust in AI outputs and decision-making processes. Confidentiality breaches could expose proprietary research or personal data, violating GDPR and other data protection regulations. The disruption to AI services could also affect operational continuity. Given the local access requirement, insider threats or compromised internal systems pose a realistic attack vector. The lack of known exploits currently provides a window for proactive defense, but the high severity necessitates urgent attention.

1. Upgrade all NVIDIA NeMo Framework deployments to version 2.5.1 or later immediately to apply the security fix. 2. Restrict access to systems running NeMo to trusted personnel only, enforcing strict access controls and monitoring for unusual activity. 3. Implement application whitelisting and sandboxing around NeMo processes to limit the impact of potential code injection. 4. Conduct thorough input validation and sanitization on data fed into NeMo components to reduce the risk of malicious input exploitation. 5. Employ endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts. 6. Regularly audit and review privilege assignments to minimize unnecessary local privileges that could be leveraged in exploitation. 7. Integrate NeMo vulnerability scanning into the organization's vulnerability management program to ensure timely detection of outdated versions. 8. Educate developers and operators on secure coding practices and the risks associated with code injection vulnerabilities in AI frameworks.
