From 6656d2f1d9d889b7b50b8484bab0a7d6a73c4793 Mon Sep 17 00:00:00 2001 From: Dorian Date: Fri, 6 Mar 2026 03:26:56 +0000 Subject: [PATCH] fix: implement 22 security pentest remediation fixes Server-side session management with SHA-256 hashed tokens and HttpOnly cookies. Auth middleware gating all RPC/WS/proxy routes with method allowlist. Login rate limiting (5/60s per IP). CORS restricted to config origin. Docker registry allowlist. App ID and path validation. P2P message sanitization (HTML + log injection). Onion address and known-peer validation. Nginx security headers (CSP, X-Frame-Options, etc.) and AIUI proxy auth. Systemd hardening (non-root, NoNewPrivileges, ProtectSystem).

call it before any filesystem or command usage; also apply in `get_data_dirs_for_app` (line 763) and `get_containers_for_app` +- [x] **FIX-007** — fix(AUTH-003): add rate limiting to `core/archipelago/src/api/rpc/auth.rs` `handle_auth_login` — track failed attempts per IP with a sliding window (max 5 failures per 60 seconds); return 429 with `Retry-After` header when exceeded; use `Arc>>>` in `RpcHandler` +- [x] **FIX-008** — fix(AUTH-008): validate incoming P2P messages in `core/archipelago/src/api/handler.rs` `handle_node_message` (line 125-145) — verify `from_pubkey` is a valid ed25519 public key format (`^[0-9a-f]{64}$`), add an optional HMAC or ed25519 signature field for message authenticity, and rate-limit by source IP +- [x] **FIX-009** — fix(AUTH-009): replace `CORS_ANY` wildcard in `core/archipelago/src/api/handler.rs` (lines 15, 108, 118, 142, 154, 173) — remove the `const CORS_ANY: &str = "*"` constant; set `Access-Control-Allow-Origin` to the node's own origin (from `Config.host_ip` or request `Origin` header validated against an allowlist); add `Vary: Origin` header +- [x] **FIX-010** — fix(AUTH-011): ensure `/proxy/lnd/*` route in `core/archipelago/src/api/handler.rs` `handle_lnd_proxy` (line 67-68) is gated by the session validation middleware added in FIX-002; additionally forward the LND macaroon only from server-side config, never from client headers +- [x] **FIX-011** — fix(XSS-004): add security headers to `image-recipe/configs/nginx-archipelago.conf` in both `server` blocks — add `X-Content-Type-Options: nosniff`, `X-Frame-Options: SAMEORIGIN`, `Referrer-Policy: strict-origin-when-cross-origin`, `Permissions-Policy: camera=(), microphone=(), geolocation=()`, and a baseline `Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'` (with `frame-src` exceptions for app iframes) +- [x] **FIX-012** — fix(XSS-007): remove the blanket `Access-Control-Allow-Origin $http_origin` echo pattern from nginx config if present; ensure nginx does not add its own CORS headers that override the backend's restricted CORS (from FIX-009); confirm only same-origin requests are allowed for `/rpc/` and `/ws` locations +- [x] **FIX-013** — fix(SSRF-001): add `validate_onion()` call at the top of `core/archipelago/src/node_message.rs` `check_peer_reachable` (line 115) — currently missing, unlike `send_to_peer` which already validates; this prevents arbitrary host/port injection via the `onion` parameter +- [x] **FIX-014** — fix(SSRF-002): ensure `node-send-message` RPC is behind auth middleware (FIX-002); additionally, in `core/archipelago/src/api/rpc/peers.rs` `handle_node_send_message` (line 50-67), validate that the `onion` address exists in the node's known peer list (`peers::load_peers`) before sending — prevent SSRF to arbitrary Tor destinations +- [x] **FIX-015** — fix(AUTH-006): implement functional logout in `core/archipelago/src/api/rpc/auth.rs` `handle_auth_logout` (line 34-36) — extract session token from request cookie, remove it from the server-side session store, and return a `Set-Cookie` header that expires the cookie +- [x] **FIX-016** — fix(AUTH-012): ensure `/api/container/logs` route in `core/archipelago/src/api/handler.rs` `handle_container_logs_http` (line 64-66) is gated by the session validation middleware added in FIX-002; also validate `app_id` query parameter with `validate_app_id()` from FIX-006 +- [x] **FIX-017** — fix(XSS-001): sanitize P2P message content in `core/archipelago/src/node_message.rs` `store_received` (line 40-42) — strip or escape HTML entities (`<`, `>`, `&`, `"`, `'`) from `message` and `from_pubkey` before storing; also ensure the Vue frontend component rendering messages uses `{{ }}` text interpolation (not `v-html`) +- [x] **FIX-018** — fix(INJ-001): validate `manifest_path` in `core/archipelago/src/api/rpc/container.rs` `handle_container_install` (line 17-18) — canonicalize the path and verify it starts with the `apps/` directory under `config.data_dir`; reject paths containing `..` segments; reject absolute paths outside the allowed base +- [x] **FIX-019** — fix(INJ-006): add authentication to `/aiui/api/claude/` in `image-recipe/configs/nginx-archipelago.conf` (lines 17-28 and 371-382) — add `auth_request` directive pointing to an internal auth-check endpoint on the backend (e.g., `/internal/auth-check` that validates the session cookie), or restrict access to authenticated sessions via cookie check in the `location` block +- [x] **FIX-020** — fix(XSS-005): gate `echo`/`server.echo` behind authentication in `core/archipelago/src/api/rpc/mod.rs` (lines 87-88) — remove `echo` from the unauthenticated allowlist so it requires a valid session; alternatively, strip or limit `message` param to alphanumeric + basic punctuation +- [x] **FIX-021** — fix(INJ-007): sanitize log output in `core/archipelago/src/api/handler.rs` `handle_node_message` (line 136) — replace newlines (`\n`, `\r`) and ANSI escape sequences in `from` and `msg` with safe representations before passing to `tracing::info!`; use `.replace('\n', "\\n").replace('\r', "\\r")` +- [x] **FIX-022** — fix: harden `image-recipe/configs/archipelago.service` — change `User=root` to `User=archipelago` (dedicated non-root service account); set `Environment="ARCHIPELAGO_DEV_MODE=false"`; add `NoNewPrivileges=true`, `ProtectSystem=strict`, `ReadWritePaths=/var/lib/archipelago`; this reduces blast radius for all findings +- [x] **VERIFY** — test: re-run pentest curl probes from the exploitation report against all 21 finding endpoints to confirm: unauthenticated requests return 401, path traversal payloads are rejected, CORS headers are restrictive, security headers are present, WebSocket requires auth, and the service runs as non-root with dev mode disabled
