NVIDIA NeMo Framework enthält eine Schwachstelle, bei der ein Angreifer durch das Schreiben einer beliebigen Datei in ein eingeschränktes Verzeichnis eine unsachgemäße Beschränkung eines Pfadnamens verursachen könnte. Ein erfolgreicher Exploit dieser Schwachstelle

The primary impact of CVE-2025-23250 is the potential for arbitrary file access. An attacker who successfully exploits this vulnerability can write files to restricted directories, effectively bypassing security controls. This could lead to code execution if the attacker can upload and execute malicious code. Data tampering is also a significant risk, as attackers could modify or delete critical files, disrupting operations or compromising data integrity. The blast radius extends to any system utilizing the vulnerable NeMo Framework, particularly those handling sensitive data or running in untrusted environments.

Organizations utilizing NVIDIA NeMo Framework for machine learning model development, deployment, or inference are at risk. This includes research institutions, AI startups, and enterprises leveraging NeMo for natural language processing tasks. Specifically, deployments that rely on user-provided data or configurations without robust input validation are particularly vulnerable.

• python / framework: Inspect NeMo Framework application code for file writing operations. Look for instances where user-supplied input is directly used in file paths without proper sanitization.

import os

def write_file(filename, data):
    with open(filename, 'w') as f:
        f.write(data)

# Vulnerable code: filename is directly from user input
filename = input("Enter filename: ")
write_file(filename, "Some data")

• generic web: Monitor web server access logs for requests containing unusual or unexpected file paths within NeMo Framework application directories. Look for patterns indicative of directory traversal attempts. • generic web: Check for unexpected files appearing in NeMo Framework application directories, particularly files with unusual extensions or names.

The primary mitigation for CVE-2025-23250 is to upgrade to NVIDIA NeMo Framework version 25.02 or later. If an immediate upgrade is not feasible, consider implementing strict input validation and sanitization to prevent attackers from manipulating file paths. Review and restrict file write permissions within the NeMo Framework environment. While a direct WAF rule is unlikely, implementing general file upload restrictions can help. Monitor system logs for unusual file access patterns or attempts to write to restricted directories.
