Overview
A high-severity vulnerability, identified as CVE-2025-33204, has been discovered in the NVIDIA NeMo Framework. This flaw resides within the NLP (Natural Language Processing) and LLM (Large Language Model) components of the framework, affecting all platforms. Maliciously crafted data provided by an attacker can trigger code injection, potentially leading to severe consequences.
Technical Details
CVE-2025-33204 stems from insufficient input validation within the NeMo Framework’s NLP and LLM processing modules. An attacker can leverage this vulnerability by crafting specific input data that, when processed by the framework, results in the execution of arbitrary code. This code injection can occur due to the framework’s failure to properly sanitize or escape user-supplied input before it is used in code execution contexts.
The attack vector involves sending specially crafted data to NeMo Framework’s API endpoints or processing pipelines that handle NLP or LLM tasks. Successful exploitation allows the attacker to execute commands on the system with the privileges of the NeMo Framework process.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-33204 is 7.8, indicating a HIGH severity. This score reflects the potential for significant impact, including code execution, privilege escalation, information disclosure, and data tampering.
- CVSS Score: 7.8
- Vector: (Example – This will vary based on actual Vector) CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (This is an example vector and needs to be replaced by the real vector when available)
- Severity: HIGH
Possible Impact
A successful exploit of CVE-2025-33204 can have serious repercussions:
- Code Execution: Attackers can execute arbitrary code on the affected system, potentially gaining complete control.
- Privilege Escalation: Attackers might be able to escalate their privileges to gain higher-level access to the system.
- Information Disclosure: Sensitive data processed by the NeMo Framework could be exposed to the attacker.
- Data Tampering: Attackers could modify or delete data managed by the NeMo Framework.
Mitigation and Patch Steps
NVIDIA has released a patch to address CVE-2025-33204. It is strongly recommended that users of the NVIDIA NeMo Framework upgrade to the latest version as soon as possible. Follow these steps to mitigate the vulnerability:
- Upgrade NeMo Framework: Download and install the latest version of the NVIDIA NeMo Framework from NVIDIA’s official website.
- Verify Installation: After upgrading, verify that the vulnerability is resolved by checking the NeMo Framework release notes or by testing with a safe, non-production environment.
- Monitor Systems: Continuously monitor systems running NeMo Framework for suspicious activity.
