CVE-2025-23360
📋 TL;DR
CVE-2025-23360 is a relative path traversal vulnerability in NVIDIA Nemo Framework that allows authenticated users to write arbitrary files to unintended locations. Successful exploitation could lead to code execution and data tampering. This affects organizations using NVIDIA Nemo Framework for AI/ML workloads.
💻 Affected Systems
- NVIDIA Nemo Framework
📦 What is this software?
Nemo by Nvidia
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary code execution, data destruction, or lateral movement within the environment.
Likely Case
Data tampering, service disruption, or limited file system manipulation by authenticated users.
If Mitigated
Contained impact with only authorized file operations possible due to proper access controls and monitoring.
🎯 Exploit Status
Requires authenticated access and knowledge of vulnerable endpoints; path traversal techniques are well-documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NVIDIA advisory for specific patched versions
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5623
Restart Required: No
Instructions:
1. Review NVIDIA advisory CVE-2025-23360. 2. Update NVIDIA Nemo Framework to patched version. 3. Verify patch application and test functionality.
🔧 Temporary Workarounds
Restrict File Write Operations
allImplement strict file permission controls and validate all file paths before write operations.
chmod 644 sensitive_directories/*
Implement input validation for all file path parameters
🧯 If You Can't Patch
- Implement strict access controls to limit which users can access Nemo Framework
- Deploy file integrity monitoring to detect unauthorized file writes
🔍 How to Verify
Check if Vulnerable:
Check NVIDIA Nemo Framework version against advisory; test for path traversal using controlled payloads.Check Version:
nemo --version or check package manager (pip list | grep nemo)Verify Fix Applied:
Verify updated version matches patched version in advisory; test path traversal attempts fail.📡 Detection & Monitoring
Log Indicators:
- Unusual file write operations outside expected directories
- Path traversal patterns in file paths (../ sequences)
- Failed authentication attempts followed by file operations
Network Indicators:
- HTTP requests with ../ sequences in parameters
- Unusual file upload patterns to Nemo endpoints
SIEM Query:
