NVIDIA NeMo Bibliothek für alle Plattformen enthält eine Schwachstelle in der Komponente zum Laden von Modellen, wobei ein Angreifer durch das Laden von .nemo-Dateien mit bösartig gestalteten Metadaten Code-Injection verursachen könnte. A

The primary impact of CVE-2025-23304 is the potential for remote code execution (RCE). By crafting a malicious .nemo file and successfully loading it into the NeMo Framework, an attacker could execute arbitrary code on the affected system. This could allow them to gain control of the system, steal sensitive data, or install malware. The vulnerability's impact is amplified by the fact that it affects the model loading component, a core functionality of the NeMo Framework, making it a potentially attractive target for attackers. Data tampering is also a risk, as the attacker could modify model data, leading to unpredictable behavior or incorrect results.

Organizations and developers utilizing NVIDIA NeMo Framework for building and deploying conversational AI models are at risk. This includes those using NeMo in production environments, particularly those handling sensitive data or integrating with critical systems. Users relying on untrusted sources for .nemo files are at heightened risk.

• python / model-loading:

import nemo
import hashlib

def check_nemo_file(filepath):
    try:
        with open(filepath, 'rb') as f:
            file_content = f.read()
            hash_value = hashlib.sha256(file_content).hexdigest()
            # Compare hash against known malicious hashes (if available)
            if hash_value in ['malicious_hash_example']: # Replace with actual hashes
                print(f"Potential malicious file detected: {filepath}")
                return True
            return False
    except Exception as e:
        print(f"Error processing file: {e}")
        return False

# Example usage
filepath = 'path/to/your/nemo_file.nemo'
if check_nemo_file(filepath):
    print("File is potentially malicious.")
else:
    print("File appears safe.")

• generic web: Check for unusual file extensions (.nemo) being uploaded or processed by NeMo-based applications.

The primary mitigation for CVE-2025-23304 is to upgrade to NVIDIA NeMo Framework version 2.3.2 or later. This version includes a fix that prevents the code injection vulnerability. If upgrading immediately is not feasible, carefully scrutinize all .nemo files before loading them, ensuring they originate from trusted sources. Consider implementing input validation to sanitize metadata within .nemo files. While a WAF or proxy cannot directly address this vulnerability, they can be configured to block suspicious file uploads or network traffic associated with known malicious .nemo file patterns. After upgrading, confirm the fix by attempting to load a known malicious .nemo file (in a controlled environment) and verifying that it is rejected.
