CVE-2025-33178
📋 TL;DR
The NVIDIA NeMo Framework contains a code injection vulnerability in its BERT services component that allows attackers to execute arbitrary code by sending malicious data. This affects all platforms running vulnerable versions of NVIDIA NeMo Framework and can lead to complete system compromise.
💻 Affected Systems
- NVIDIA NeMo Framework
📦 What is this software?
Nemo by Nvidia
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining root/admin privileges, exfiltrating sensitive data, and tampering with or destroying critical systems.
Likely Case
Unauthorized code execution leading to data theft, privilege escalation, and potential lateral movement within the network.
If Mitigated
Limited impact if proper network segmentation, least privilege, and input validation controls are implemented.
🎯 Exploit Status
CWE-94 indicates improper control of generation of code ('Code Injection'), suggesting attackers can inject malicious code through data inputs to BERT services.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NVIDIA advisory for specific patched version
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5718
Restart Required: Yes
Instructions:
1. Review NVIDIA advisory at provided URL
2. Identify current NeMo Framework version
3. Update to patched version following NVIDIA's instructions
4. Restart affected services
🔧 Temporary Workarounds
Network Segmentation
allIsolate NeMo Framework instances from untrusted networks and limit access to trusted sources only
Input Validation
allImplement strict input validation and sanitization for all data sent to BERT services
🧯 If You Can't Patch
- Isolate vulnerable systems in a dedicated network segment with strict access controls
- Implement application-level firewalls to monitor and block suspicious requests to BERT services
🔍 How to Verify
Check if Vulnerable:
Check NeMo Framework version against NVIDIA's advisory. If running a version prior to the patched version, the system is vulnerable.Check Version:
Check NeMo Framework documentation for version checking command specific to your deploymentVerify Fix Applied:
Verify NeMo Framework version matches or exceeds the patched version specified in NVIDIA's advisory📡 Detection & Monitoring
Log Indicators:
- Unusual process execution from BERT services
- Suspicious command execution patterns
- Error logs showing code injection attempts
Network Indicators:
- Unusual network connections originating from NeMo Framework instances
- Suspicious payloads sent to BERT service endpoints
SIEM Query:
source="nemo_framework" AND (event_type="process_execution" OR event_type="error") AND message CONTAINS "injection" OR "malicious"
