CVE-2023-31036
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA Triton Inference Server for Linux and Windows contains a vulnerability where, when it is launched with the non-default command line option --model-control explicit, an attacker may use the model load API to cause a relative path traversal. A successful exploit of this vulnerability may lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA Triton Inference Server contains a path traversal vulnerability when the non-default --model-control explicit option is enabled. An attacker can exploit the model load API by providing paths with relative traversal sequences (e.g., ../../../) to access files outside the intended model directory. This can lead to code execution, denial of service, privilege escalation, information disclosure, or data tampering.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Triton Inference Server installationLocate the Triton server binary or container. Common paths: /opt/tritonserver, /usr/local/bin/tritonserver, or check running containers with 'docker ps'. Query the version using '--version' flag or check the image tag.Affected if Triton Inference Server is not installed or version cannot be determined
-
Verify installed versionRun 'tritonserver --version' or inspect the container image tag. Compare the version number against the affected range: versions prior to 2.40.Affected if Installed version is lower than 2.40 (e.g., 2.38.x, 2.39.x)
-
Check if model-control explicit is enabledInspect the Triton server startup command or configuration. For containers, run 'docker inspect <container>' and review the Cmd or Args section. Look for '--model-control explicit' in the launch arguments.Affected if The --model-control explicit flag is present in the server startup parameters
-
Confirm model load API exposureVerify the Triton HTTP/REST or gRPC API endpoint is accessible. Check network configuration or firewall rules. The vulnerability is exploitable via the model load API endpoint when explicit mode is enabled.Affected if The Triton model load API is network-accessible without strict authentication
You are affected if Triton Inference Server version is below 2.40 AND the --model-control explicit option is enabled, exposing the model load API to path traversal attacks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.40
Avoid using --model-control explicit in production deployments unless strictly required; if needed, implement strict path validation to prevent traversal sequences in model load requests and restrict API access via authentication and network controls.
Triton Inference Server 2.40 or later
- 1. Identify the current Triton Inference Server version in use (e.g., check via Docker image tag or installed package version)
- 2. Back up all model repositories and configuration files
- 3. Stop the Triton Inference Server service
- 4. Upgrade Triton Inference Server to version 2.40 or later
- 5. If using the --model-control explicit option, verify that the upgrade resolves the path traversal vulnerability
- 6. Restart the Triton Inference Server service
- 7. Test model loading functionality to confirm normal operation
