CVE-2025-23327
📋 TL;DR
NVIDIA Triton Inference Server contains an integer overflow vulnerability (CWE-190) where specially crafted inputs could cause denial of service or data tampering. This affects both Windows and Linux deployments of Triton Inference Server. Organizations using vulnerable versions for AI inference workloads are at risk.
💻 Affected Systems
- NVIDIA Triton Inference Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption through denial of service combined with potential data corruption or tampering in inference results, affecting downstream applications.
Likely Case
Service instability or crashes leading to inference pipeline interruptions and degraded AI service availability.
If Mitigated
Limited impact with proper input validation and network segmentation, potentially causing only temporary service degradation.
🎯 Exploit Status
Exploitation requires sending specially crafted inputs to the inference server, which could be done via API calls. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 24.09 or later
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5687
Restart Required: Yes
Instructions:
1. Download NVIDIA Triton Inference Server version 24.09 or later from NVIDIA's official channels. 2. Stop the current Triton service. 3. Install the updated version following NVIDIA's installation guide. 4. Restart the Triton service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement input validation at the API gateway or load balancer to filter suspicious requests before they reach Triton.
Network Segmentation
linuxRestrict Triton server access to trusted clients only using firewall rules.
# Example Linux iptables rule
sudo iptables -A INPUT -p tcp --dport 8000 -s trusted_ip_range -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 8000 -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to limit Triton server exposure to only necessary clients.
- Deploy Web Application Firewall (WAF) or API gateway with input validation rules to filter malicious requests.
🔍 How to Verify
Check if Vulnerable:
Check Triton server version using the Triton client or by examining the server logs/configuration. Versions before 24.09 are vulnerable.Check Version:
curl -v http://triton-server:8000/v2/health/ready 2>&1 | grep -i versionVerify Fix Applied:
Confirm the Triton server version is 24.09 or later and test inference functionality with normal workloads.📡 Detection & Monitoring
