CVE-2025-23313
📋 TL;DR
CVE-2025-23313 is a code injection vulnerability in NVIDIA's NeMo Framework NLP component that allows attackers to execute arbitrary code by providing malicious data. Successful exploitation could lead to remote code execution, privilege escalation, data theft, or system compromise. All users running vulnerable versions of NVIDIA NeMo Framework are affected.
💻 Affected Systems
- NVIDIA NeMo Framework
📦 What is this software?
Nemo by Nvidia
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over the affected system, data exfiltration, and lateral movement within the network.
Likely Case
Unauthorized code execution leading to data tampering, information disclosure, and potential privilege escalation within the NeMo Framework context.
If Mitigated
Limited impact through proper input validation and sandboxing, potentially resulting in denial of service rather than full code execution.
🎯 Exploit Status
Exploitation requires the attacker to provide malicious data to the NLP component, which could be achieved through various input vectors.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NVIDIA advisory for specific patched versions
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5689

4. Verify the update was successful
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for all data processed by the NLP component
Network Segmentation
allIsolate NeMo Framework instances from untrusted networks and limit access to trusted sources only
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure to trusted sources only
- Deploy application-level firewalls or WAFs to filter malicious input patterns
🔍 How to Verify
Check if Vulnerable:
Check the NeMo Framework version against the vulnerable version range specified in NVIDIA's advisoryCheck Version:
Check NeMo Framework documentation for version checking commands specific to your deploymentVerify Fix Applied:
Verify the installed version matches or exceeds the patched version listed in NVIDIA's advisory📡 Detection & Monitoring
Log Indicators:
- Unusual process execution from NeMo Framework components
