Overview
CVE-2025-33205 is a high-severity vulnerability affecting the NVIDIA NeMo framework. This vulnerability stems from the insecure use of a predefined variable, allowing an attacker to potentially inject functionality from an untrusted source. Successful exploitation could lead to arbitrary code execution within the context of the NeMo framework.
Technical Details
The vulnerability resides in how the NVIDIA NeMo framework handles predefined variables. Specifically, an attacker can manipulate a predefined variable in a way that causes the framework to include code or functionality from an external and potentially malicious source. The lack of proper validation and sanitization of these predefined variables creates an opportunity for code injection. The specific vulnerable component and code location are detailed in NVIDIA’s advisory (linked below).
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-33205 is 7.3 (HIGH).
This score reflects the potential for remote code execution without requiring significant user interaction, as well as the confidentiality, integrity, and availability impact if the vulnerability is successfully exploited.
Possible Impact
A successful exploit of CVE-2025-33205 can have serious consequences, including:
- Code Execution: An attacker could execute arbitrary code on the system, potentially gaining full control.
- Data Breach: Sensitive data processed by the NeMo framework could be compromised.
- System Compromise: The affected system could be fully compromised and used for malicious purposes.
- Denial of Service: The vulnerability could be exploited to cause a denial-of-service condition, rendering the NeMo framework and related applications unavailable.
Mitigation and Patch Steps
The recommended mitigation is to update your NVIDIA NeMo framework to the latest patched version as provided by NVIDIA. Specifically:
- Upgrade NeMo Framework: Download and install the latest version of the NeMo framework from the official NVIDIA channels. Refer to NVIDIA’s security advisory for specific version details.
- Review Configuration: Examine your NeMo framework configuration for any potentially vulnerable uses of predefined variables and implement stricter validation.
