From 1af082c4107c2070ecaedb9ff57d3eaa93d8c625 Mon Sep 17 00:00:00 2001 From: Shankar Date: Wed, 29 Apr 2026 18:51:57 +0000 Subject: [PATCH] feat(scep): SCEP probe in network scanner for fleet-readiness assessment MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 11.5 of the SCEP RFC 8894 + Intune master bundle. Adds an operator-facing SCEP probe that issues GetCACaps + GetCACert against an arbitrary SCEP server URL and returns a structured posture snapshot (reachable + advertised caps + RFC 8894 / AES / POST / Renewal / SHA-256 / SHA-512 support flags + CA cert subject + issuer + NotBefore + NotAfter + days-to-expiry + algorithm + chain length). Two operator use cases per the master prompt: 1. Pre-migration assessment — probe an existing EJBCA / NDES SCEP server before switching to certctl to see what capabilities it advertises and what the CA cert looks like. 2. Compliance posture audits — periodic ad-hoc probes against the operator's own SCEP servers to flag drift. Capability-only — does NOT POST a CSR per the spec (would consume slot allocations on the target server + create audit noise). Standalone CLI binary explicitly out of scope (per the master prompt §11.5.6 and the operator's confirmation): the probe code lands inside certctl; a future thin Cobra wrapper is a separate decision. Backend (six new + one extended file): * internal/domain/network_scan.go — new SCEPProbeResult struct with every probe field documented for the GUI's display layer. * migrations/000021_scep_probe_results.up.sql + .down.sql — new scep_probe_results table with TEXT id, target_url, all probe flags, CA cert metadata, probed_at, probe_duration_ms, error. Two indexes: idx_scep_probe_results_probed_at (DESC) for the 'recent probes' GUI query, idx_scep_probe_results_target_url (target_url, probed_at DESC) for the future per-URL history view. * internal/repository/interfaces.go — new SCEPProbeResultRepository interface (Insert + ListRecent). * internal/repository/postgres/scep_probe_results.go — Postgres implementation. ListRecent clamps limit to [1, 200]; on read re-derives ca_cert_days_to_expiry against the query-time wall clock so 'X days remaining' stays fresh. * internal/service/scep_probe.go — ProbeSCEP(ctx, url) on NetworkScanService. Validation order: 1. Up-front URL validation via validation.ValidateSafeURL (defaults to validation.ValidateSafeURL but injectable for tests via the new scepValidateURL field on the service). 2. Dial-time SSRF re-check via SafeHTTPDialContext on the http.Transport (defends against DNS rebinding). 3. GET ?operation=GetCACaps + GET ?operation=GetCACert. GetCACert handles three response shapes: PKCS#7 SignedData certs-only envelope (multi-cert), raw DER (single-cert), and PEM-wrapped DER (non-conforming servers). Times out at 30s; uses a 1MB body cap for DoS defense; wraps the result + persists via the repo (nil-safe) before returning. describeCertAlgorithm helper returns 'RSA-N' / 'ECDSA-curve' / 'Ed25519' / 'DSA' for the GUI's algorithm column. * internal/service/network_scan.go — added scepProbeRepo + scepHTTPClient + scepValidateURL + scepIDFn + nowFn fields; SetSCEPProbeRepo wires the repo at startup. * internal/api/handler/network_scan.go — extended NetworkScanService interface with ProbeSCEP + ListRecentSCEPProbes; added two new HTTP handlers: POST /api/v1/network-scan/scep-probe (body {url}) GET /api/v1/network-scan/scep-probes (recent history) Synchronous probe; HTTP 200 with the result body for both success and reachable-but-failed cases (so the GUI can render the failure tone with the operator-actionable error message). * internal/api/router/router.go — registered the two routes inline after the existing network-scan target endpoints. * api/openapi.yaml — documented both endpoints (operationId probeSCEP + listSCEPProbes) with full schema + response codes. * cmd/server/main.go — wires the new SCEPProbeResultRepository onto the network scan service via SetSCEPProbeRepo right after the existing NewNetworkScanService construction. Backend tests (6 new — exit-criteria-named per the master prompt): * TestProbeSCEP_AdvertisesAllCaps — happy path, full RFC 8894 capability set, ECDSA P-256 CA cert, 365-day expiry. * TestProbeSCEP_MissingSCEPStandard — pre-RFC-8894 server (only POSTPKIOperation + SHA-1 + DES3); SupportsRFC8894 = false. * TestProbeSCEP_GetCACertExpired — CA cert NotAfter 30d in the past; CACertExpired = true. * TestProbeSCEP_Unreachable — connect to TCP port 1; probe returns Reachable=false + non-empty Error. * TestProbeSCEP_RejectsReservedIP — http://169.254.169.254/scep (EC2 metadata literal) rejected by the up-front validation.ValidateSafeURL gate; result captures the error without ever issuing the HTTP call. * TestProbeSCEP_PEMWrappedCert — server returns PEM instead of raw DER for GetCACert; the fallback parse path handles it. Frontend (one extended file + types/client): * web/src/api/types.ts — SCEPProbeResult + SCEPProbesResponse. * web/src/api/client.ts — probeSCEPServer + listSCEPProbes helpers. * web/src/pages/NetworkScanPage.tsx — new SCEPProbeSection component + ProbeResultPanel (with capability badges + CA cert details panel + raw caps line) + SCEPProbeHistoryTable. Form rejects empty URL with inline error before calling the API. Reload mutation goes through useTrackedMutation with explicit invalidates: [['scep-probes']] (M-009 contract). Frontend tests (5 new + 0 regressions): * Scep probe section header + form renders. * Empty URL is rejected with inline error and never calls the probe endpoint. * Successful probe renders capability badges + CA cert subject + days-remaining inline panel. * Probe-level errors are surfaced in the inline panel (no result panel rendered). * Recent-probes history table renders one row per probe. * (Existing 2 NetworkScanPage XSS-hardening tests stub the new listSCEPProbes endpoint to an empty list so they still pass.) Verification: * gofmt clean on touched files * go vet ./... clean * staticcheck on service+handler+router+repository+cmd-server clean * go test -short across service+handler+router+repository+cmd-server + integration: all green (existing + 6 new probe tests pass) * Frontend tsc --noEmit clean * Vitest: 7/7 NetworkScanPage tests pass (2 existing XSS + 5 new probe section) * G-3 docs-drift CI guard reproduced locally clean (no new env vars) * M-009 hard-zero useMutation guard clean (probe mutation goes through useTrackedMutation) * openapi-parity guard satisfied (both new routes documented) * The mockNetworkScanService in handler + integration packages extended with stub Probe methods; targeted coverage stays in scep_probe_test.go. Out of scope (per master prompt §11.5.6 + operator confirmation): * Standalone certctl-scan CLI binary — separate decision, ~1d of follow-up work when/if shipped.
