CVE-2025-33250
📋 TL;DR
CVE-2025-33250 is a remote code execution vulnerability in NVIDIA's NeMo Framework that allows attackers to execute arbitrary code on affected systems. This affects organizations using NVIDIA NeMo for AI/ML development and deployment. Successful exploitation could compromise AI models, training data, and underlying infrastructure.
💻 Affected Systems
- NVIDIA NeMo Framework
📦 What is this software?
Nemo by Nvidia
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to execute arbitrary code, steal sensitive AI models and data, pivot to other systems, and cause permanent data loss or corruption.
Likely Case
Attacker gains code execution on NeMo Framework instances, potentially compromising AI models, training data, and accessing sensitive information stored in the environment.
If Mitigated
Limited impact with proper network segmentation, minimal privileges, and monitoring in place, potentially only affecting isolated NeMo instances.
🎯 Exploit Status
Based on CVSS score and CWE-94 (Code Injection), exploitation likely requires some technical knowledge but no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NVIDIA advisory for specific patched versions
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5762
Restart Required: Yes
Instructions:
1. Review NVIDIA advisory for affected versions. 2. Update NVIDIA NeMo Framework to patched version. 3. Restart all NeMo services and containers. 4. Verify update was successful.
🔧 Temporary Workarounds
Network Segmentation
allIsolate NeMo Framework instances from untrusted networks and internet access
Container Security Hardening
linuxRun NeMo containers with minimal privileges and read-only filesystems where possible
docker run --read-only --cap-drop=ALL nvidia/nemo:tag
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure
- Deploy runtime protection and monitoring for suspicious process execution
🔍 How to Verify
Check if Vulnerable:
Check NeMo Framework version against NVIDIA advisory. Review system logs for unexpected process execution.Check Version:
python -c "import nemo; print(nemo.__version__)" or check container/pip package versionVerify Fix Applied:
Confirm NeMo Framework version matches patched version from NVIDIA advisory. Test functionality remains intact.📡 Detection & Monitoring
Log Indicators:
- Unexpected process execution from NeMo context
- Unusual network connections from NeMo services
- File creation/modification in NeMo directories
Network Indicators:
- Unusual outbound connections from NeMo instances
- Suspicious inbound requests to NeMo API endpoints
SIEM Query:
process.name:python AND parent.process.name:nemo AND process.cmdline:contains('exec' OR 'system' OR 'subprocess')
