CVE-2025-23315

7.8 HIGH

📋 TL;DR

CVE-2025-23315 is a code injection vulnerability in NVIDIA NeMo Framework's export and deploy 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 of NVIDIA NeMo Framework across all platforms are affected.

💻 Affected Systems

Products:
  • NVIDIA NeMo Framework
Versions: All versions prior to patched release
Operating Systems: All platforms (Linux, Windows, etc.)
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the export and deploy component specifically; any system using NeMo Framework with this component enabled is vulnerable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with attacker gaining root/admin privileges, complete data exfiltration, and persistent backdoor installation.

🟠

Likely Case

Unauthorized code execution within the NeMo Framework context leading to data tampering, privilege escalation, and lateral movement.

🟢

If Mitigated

Limited impact with proper input validation and sandboxing, potentially only denial of service or limited information disclosure.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Requires attacker to provide malicious data to the export/deploy component; likely requires some level of access or ability to influence data processing.

🛠️ 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

Restart Required: Yes

Instructions:

1. Review NVIDIA advisory CVE-2025-23315
2. Update NVIDIA NeMo Framework to patched version
3. Restart affected services/systems
4. Verify patch application

🔧 Temporary Workarounds

Disable Export/Deploy Component

all

Temporarily disable or restrict access to the vulnerable export and deploy component

# Configuration dependent - consult NeMo documentation for component disabling

Input Validation Enhancement

all

Implement strict input validation and sanitization for data processed by export/deploy functions

# Application-specific implementation required

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate NeMo Framework systems
  • Deploy application-level firewalls with strict input validation rules

🔍 How to Verify

Check if Vulnerable:

Check NeMo Framework version against NVIDIA advisory; systems running unpatched versions are vulnerable

Check Version:

nemo --version or check package manager (pip show nemo-toolkit)

Verify Fix Applied:

Verify NeMo Framework version matches patched version from NVIDIA advisory and test export/deploy functionality

📡 Detection & Monitoring

Log Indicators:

  • Unusual export/deploy activity patterns
  • Unexpected process execution from NeMo components
  • Error logs showing malformed data processing

Network Indicators:

  • Anomalous data transfers to/from NeMo systems
  • Unexpected network connections from NeMo processes

SIEM Query:

source="nemo_logs" AND (event="export" OR event="deploy") AND data_size>threshold
