CVE-2025-23310
📋 TL;DR
CVE-2025-23310 is a critical stack buffer overflow vulnerability in NVIDIA Triton Inference Server that allows attackers to execute arbitrary code remotely by sending specially crafted inputs. This affects all organizations using vulnerable versions of NVIDIA Triton Inference Server on Windows or Linux systems. Successful exploitation could lead to complete system compromise.
💻 Affected Systems
- NVIDIA Triton Inference Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with SYSTEM/root privileges leading to complete system takeover, data exfiltration, and persistent backdoor installation.
Likely Case
Denial of service through server crashes and potential information disclosure from memory corruption.
If Mitigated
Limited impact through network segmentation and input validation controls, potentially reduced to service disruption.
🎯 Exploit Status
CVSS 9.8 indicates trivial exploitation requiring no authentication. Weaponization likely given the critical nature and widespread use of Triton.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NVIDIA advisory for specific patched version
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5687
Restart Required: Yes
Instructions:
1. Review NVIDIA advisory for patched version. 2. Backup current configuration. 3. Stop Triton service. 4. Install patched version. 5. Restart Triton service. 6. Verify functionality.
🔧 Temporary Workarounds
Network Segmentation
allRestrict access to Triton servers to only trusted networks and clients
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_IP_RANGE" port protocol="tcp" port="8000-8002" accept'
netsh advfirewall firewall add rule name="Triton Access" dir=in action=allow protocol=TCP localport=8000-8002 remoteip=TRUSTED_IP_RANGE
Input Validation Proxy
allDeploy a reverse proxy with strict input validation before Triton
🧯 If You Can't Patch
- Isolate Triton servers in dedicated network segments with strict firewall rules
- Implement application-level input validation and monitoring for anomalous requests
🔍 How to Verify
Check if Vulnerable:
Check Triton version against NVIDIA advisory. Vulnerable if using unpatched version.Check Version:
tritonserver --version or check server logs/configurationVerify Fix Applied:
Verify installed version matches patched version from NVIDIA advisory and test with normal inference requests.📡 Detection & Monitoring
Log Indicators:
- Unusual request patterns
- Server crashes/restarts
- Memory access violation errors
- Large or malformed input payloads
Network Indicators:
- Unusual traffic spikes to Triton ports
- Requests with abnormal payload sizes
- Connection attempts from unexpected sources
SIEM Query:
source="triton_server" AND (event_type="crash" OR event_type="error" OR message="*buffer*" OR message="*overflow*")
