CVE-2025-23361

7.8 HIGH

📋 TL;DR

The NVIDIA NeMo Framework contains a vulnerability where malicious input can cause improper control of code generation, potentially leading to remote code execution, privilege escalation, information disclosure, or data tampering. This affects all platforms running vulnerable versions of NVIDIA NeMo Framework. Attackers could exploit this to compromise systems running the framework.

💻 Affected Systems

Products:
  • NVIDIA NeMo Framework
Versions: All versions prior to the patched version
Operating Systems: All platforms (Linux, Windows, etc.)
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all deployments of NVIDIA NeMo Framework regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with attacker gaining root/admin privileges, executing arbitrary code, stealing sensitive data, and tampering with critical information.

🟠

Likely Case

Remote code execution with the privileges of the NeMo Framework process, potentially leading to lateral movement within the network.

🟢

If Mitigated

Limited impact due to network segmentation, least privilege configurations, and proper input validation controls.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Based on CVSS score and description, exploitation likely requires some technical knowledge but no authentication.

🛠️ 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. Download and install the latest patched version of NVIDIA NeMo Framework
3. Restart any services using the framework
4. Verify the patch is applied correctly

🔧 Temporary Workarounds

Network Segmentation

all

Isolate NeMo Framework instances from untrusted networks and internet access

Input Validation

all

Implement strict input validation for all data processed by NeMo Framework

🧯 If You Can't Patch

  • Disable or remove the vulnerable script if not essential for operations
  • Implement network-level controls to block external access to NeMo Framework instances

🔍 How to Verify

Check if Vulnerable:

Check NVIDIA NeMo Framework version against the patched version specified in NVIDIA advisory

Check Version:

Check NeMo Framework documentation for version check command specific to your installation

Verify Fix Applied:

Verify installed version matches or exceeds the patched version from NVIDIA advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual process execution from NeMo Framework context
  • Unexpected code generation or script execution
  • Authentication failures or privilege escalation attempts

Network Indicators:

  • Unusual network connections from NeMo Framework hosts
  • Suspicious payloads sent to NeMo Framework endpoints

SIEM Query:

Process execution where parent_process contains 'nemo' OR network_connection where dest_port in [NeMo ports] AND suspicious_payload_detected
