NVIDIA NeMo Framework には、攻撃者がリモートコード実行を引き起こす可能性のある脆弱性が存在します。この脆弱性の悪用により、コード実行、サービス拒否、情報漏えいが発生する可能性があります。

The RCE vulnerability in NVIDIA NeMo Framework allows an attacker to execute arbitrary code on a system running the framework. This could involve gaining complete control of the system, stealing sensitive data, modifying existing data, or disrupting services. The potential impact is significant, as an attacker could leverage this vulnerability to compromise the entire environment where NeMo is deployed. Depending on the application using NeMo, the blast radius could extend to downstream systems and data. While no specific exploitation patterns have been publicly linked to this CVE, the potential for arbitrary code execution aligns with high-impact vulnerabilities like Log4Shell, where attackers can inject malicious code into system processes.

Organizations and developers utilizing the NVIDIA NeMo Framework in their machine learning pipelines are at risk. This includes those deploying NeMo for natural language processing tasks, particularly in environments where external data or user input is processed without proper validation. Shared hosting environments where multiple users have access to the NeMo installation are also at increased risk.

• python / server:

import os
import subprocess

# Check for NeMo Framework version
process = subprocess.Popen(['pip', 'show', 'nvidia-nemo'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()
if 'Version:' in stdout.decode():
    version = stdout.decode().split('Version:')[1].strip()
    if version and version.startswith('2.6'):
        print('NeMo Framework version is patched.')
    else:
        print('NeMo Framework version is vulnerable.')

• generic web:

curl -I <your_nemo_endpoint>

Inspect the response headers for any unusual or unexpected content that might indicate malicious code execution.

The primary mitigation for CVE-2025-33251 is to upgrade to NVIDIA NeMo Framework version 2.6.1 or later. If immediate upgrading is not feasible due to compatibility issues or testing requirements, consider implementing temporary workarounds. While specific WAF rules are unlikely to directly address this RCE, carefully review input validation routines within NeMo applications to prevent malicious code injection. Monitor system logs for unusual process activity or unexpected file modifications that could indicate exploitation attempts. There are no specific Sigma or YARA rules available for this CVE at this time.
