Executive Summary + +Overall Risk Rating: **MEDIUM** + +The VoID eID codebase demonstrates several positive security practices — parameterized SQL queries throughout (no SQLx string interpolation), proper Sui wallet signature verification, tribe-scoped access control, comprehensive audit logging, and a `RequireSuperAdmin` middleware that re-validates against environment variables rather than trusting JWT claims. However, the audit identified several findings across authentication, infrastructure, and operational security domains that warrant remediation. + +**Top 3 Critical Risks:** + +1. **Missing OAuth2 `state` parameter** — The Discord OAuth2 login flow has no CSRF protection, allowing a session fixation attack where an attacker could bind a victim's browser session to the attacker's Discord identity. +2. **JWT token transmitted in URL query string** — After OAuth callback, the JWT bearer token is placed in a redirect URL, exposing it in browser history, Referer headers, and server logs. +3. **Hardcoded ICE/Internal secrets with weak defaults** — Murmur ICE secrets are hardcoded to `"secret"` in configuration and startup scripts, and the `INTERNAL_SECRET` environment variable defaults to `"secret"` or `"changeme"` when unset. + +--- + +## 2. Detailed Findings + +| ID | Vulnerability Name | Severity | Location | OWASP 2025 | MITRE ATT&CK | +| ------ | --------------------------------------------------------------------------- | ---------- | -------------------------------------- | ----------------------- | ------------ | +| SEC-01 | Missing OAuth2 `state` parameter (CSRF) | **High** | auth.rs | A07:2025 | T1078.004 | +| SEC-02 | JWT token in URL query string | **High** | auth.rs | A02:2025 | T1528 | +| SEC-03 | Hardcoded ICE secrets & weak defaults | **High** | murmur.ini, start.sh, authenticator.py | A02:2025 | T1552.001 | +| SEC-04 | `INTERNAL_SECRET` defaults to `"secret"` | **High** | auth.rs | A07:2025 | T1078 | +| SEC-05 | No rate limiting on authentication endpoints | **Medium** | main.rs | A07:2025 | T1110 | +| SEC-06 | Backend Docker containers run as root | **Medium** | Dockerfile | A05:2025 | T1611 | +| SEC-07 | Database error details leaked to clients | **Medium** | auth.rs, wallet.rs | A05:2025 | T1592 | +| SEC-08 | Wallet nonces have no TTL/expiration | **Medium** | wallet.rs, state.rs | A07:2025 | T1550 | +| SEC-09 | No Content-Security-Policy headers | **Medium** | nginx.conf | A05:2025 | T1059.007 | +| SEC-10 | No input length/size validation | **Low** | notes.rs, admin.rs | A03:2025 | T1499 | +| SEC-11 | GitHub Actions not SHA-pinned | **Low** | ci.yml | A08:2025 (Supply Chain) | T1195.002 | +| SEC-12 | `is_super_admin` JWT claim not revalidated in `AuthenticatedUser` extractor | **Low** | auth.rs | A01:2025 | T1078 | + +--- + +### SEC-01: Missing OAuth2 `state` Parameter (CSRF) + +**Description:** The `discord_login` endpoint at auth.rs constructs the Discord OAuth2 authorization URL without a `state` parameter. The `discord_callback` handler does not validate any `state` token. + +**Impact:** An attacker can craft a link to Discord's OAuth2 authorization endpoint using the application's client_id. When a victim clicks it, the resulting callback code can be replayed to the application, potentially binding the victim's session to an attacker-controlled Discord account (session fixation), or the reverse — forcing a login to the attacker's account. + +**Guidance/Fix:** + +```rust +// In discord_login: +let state_token = Uuid::new_v4().to_string(); +// Store state_token in a short-lived server-side store (or signed cookie) +state.oauth_states.lock().unwrap().insert(state_token.clone(), Utc::now()); + +let url = format!( + "https://discord.com/api/oauth2/authorize?client_id={}&redirect_uri={}&response_type=code&scope={}&state={}", + client_id, urlencoding::encode(&redirect_uri), scope, state_token +); + +// In discord_callback: +// Validate params.state exists and matches a stored token, then remove it +``` + +--- + +### SEC-02: JWT Token in URL Query String + +**Description:** At auth.rs, after successful Discord OAuth2 callback, the JWT is passed to the frontend via: + +```rust +Redirect::to(&format!("{}/auth/callback?token={}", frontend_url, token)) +``` + +**Impact:** The JWT appears in browser history, can leak via `Referer` headers if the callback page loads external resources, and can be logged by reverse proxies or WAFs. This is a credential exposure risk per NIST SP 800-63B §5.1.3. + +**Guidance/Fix:** Use a short-lived, one-time authorization code pattern instead: + +1. Store the JWT keyed by a random code in a server-side store (with 30s TTL). +2. Redirect with `?code=` only. +3. Frontend calls `POST /api/auth/exchange` with the code to retrieve the JWT in a response body. + +Alternatively, set the JWT as an `HttpOnly`, `Secure`, `SameSite=Strict` cookie in the redirect response instead of putting it in the URL. + +--- + +### SEC-03: Hardcoded ICE Secrets & Weak Defaults + +**Description:** + +- murmur.ini: `icesecretread=secret` and `icesecretwrite=secret` are hardcoded. +- start.sh: `export ICE_SECRET="secret"` is hardcoded. +- authenticator.py: `internal_secret = os.environ.get("INTERNAL_SECRET", "changeme")`. +- authenticator.py: Falls back to `"secret"` for ICE if env var is empty. + +**Impact:** Anyone with network access to the ICE port (6502) can authenticate and control the Murmur server — registering users, kicking users, changing server configuration. Although the port is bound to `127.0.0.1` in murmur.ini, it is exposed in the Docker container (port 6502 in Dockerfile). + +**Guidance/Fix:** + +- Generate strong random secrets at deployment time via `openssl rand -hex 32`. +- Template murmur.ini to inject `icesecretread` and `icesecretwrite` from environment variables in start.sh. +- Remove the hardcoded fallback of `"secret"` in start.sh and authenticator.py; fail loudly if the secret is not configured. +- Do NOT expose port 6502 in the Docker container or docker-compose.yml. + +--- + +### SEC-04: `INTERNAL_SECRET` Defaults to `"secret"` + +**Description:** At auth.rs: + +```rust +let configured_secret = env::var("INTERNAL_SECRET").unwrap_or_else(|_| "secret".to_string()); +``` + +If `INTERNAL_SECRET` is not set, the Mumble internal API (verify endpoint) will accept `X-Internal-Secret: secret`. + +**Impact:** If deployed without explicit `INTERNAL_SECRET` configuration, any caller who guesses the default can invoke the internal Mumble verification API, potentially impersonating the authenticator. + +**Guidance/Fix:** Fail with a panic or startup error if `INTERNAL_SECRET` is not set, similar to how `IDENTITY_HASH_PEPPER` is handled in state.rs: + +```rust +let configured_secret = env::var("INTERNAL_SECRET") + .expect("INTERNAL_SECRET must be set"); +``` + +--- + +### SEC-05: No Rate Limiting on Authentication Endpoints + +**Description:** No rate limiting middleware is applied to any endpoint, including `/api/auth/discord/login`, `/api/auth/discord/callback`, `/api/wallets/link-nonce`, `/api/wallets/link-verify`, and `/api/internal/mumble/verify`. + +**Impact:** Enables brute-force attacks against the Mumble verify endpoint, nonce flooding against the wallet linking flow, and potential OAuth abuse. + +**Guidance/Fix:** Add `tower::limit::RateLimitLayer` or use `tower_governor` crate: + +```rust +use tower_governor::{GovernorLayer, GovernorConfigBuilder}; + +let governor_conf = GovernorConfigBuilder::default() + .per_second(2) + .burst_size(5) + .finish() + .unwrap(); + +// Apply to sensitive routes +.route("/api/auth/discord/callback", get(auth::discord_callback)) + .layer(GovernorLayer { config: governor_conf }) +``` + +--- + +### SEC-06: Backend Docker Container Runs as Root + +**Description:** The backend Dockerfile and frontend Dockerfile do not define a non-root user. Containers run as `root` by default. + +**Impact:** If an attacker achieves remote code execution via the application, they have full root privileges within the container, facilitating container escape (CIS Docker Benchmark 4.1). + +**Guidance/Fix:** + +```dockerfile +# Backend Dockerfile - add before CMD: +RUN groupadd -r appuser && useradd -r -g appuser appuser +RUN mkdir -p /data && chown appuser:appuser /data +USER appuser + +# Frontend Dockerfile - add before CMD: +RUN groupadd -r appuser && useradd -r -g appuser appuser +USER appuser +``` + +Note: Nginx requires port 80 changes if running as non-root. Use port 8080 and a non-privileged nginx configuration, or use a rootless nginx image. + +--- + +### SEC-07: Database Error Details Leaked to Clients + +**Description:** Several error handlers return raw database error messages to the client: + +- auth.rs: `format!("DB Error: {}", e)` +- auth.rs: `format!("Discord token exchange failed: Status: {}, Body: {}", status, body)` +- wallet.rs: `format!("DB Error: {}", e)` + +**Impact:** Information disclosure — SQLite error messages can reveal table names, column names, and query structure, aiding further attacks. + +**Guidance/Fix:** Log the full error server-side with `tracing::error!()` and return a generic 500 error to clients: + +```rust +.map_err(|e| { + eprintln!("Database error: {}", e); // or tracing::error! + (StatusCode::INTERNAL_SERVER_ERROR, "Internal server error") +})?; +``` + +--- + +### SEC-08: Wallet Nonces Have No TTL/Expiration + +**Description:** In wallet.rs and state.rs, the `wallet_nonces` HashMap stores nonces with no expiration. Nonces are only removed when consumed. + +**Impact:** Unused nonces accumulate indefinitely (memory leak DoS potential). Additionally, a nonce generated but never consumed remains valid forever, widening the attack surface for replay if an attacker captures a nonce. + +**Guidance/Fix:** Store nonces with a timestamp and add a TTL check: + +```rust +pub wallet_nonces: Arc)>>>, + +// On retrieval, validate age: +let (nonce, created_at) = nonces.remove(&address_str) + .ok_or((StatusCode::BAD_REQUEST, "Nonce invalid or expired".into()))?; +if Utc::now() - created_at > chrono::Duration::minutes(5) { + return Err((StatusCode::BAD_REQUEST, "Nonce expired".into())); +} +``` + +--- + +### SEC-09: No Content-Security-Policy Headers + +**Description:** The nginx.conf serves the SPA without any security headers (CSP, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security). + +**Impact:** Increases susceptibility to XSS, clickjacking, and MIME-type sniffing attacks. + +**Guidance/Fix:** + +```nginx +server { + listen 80 default_server; + + add_header X-Frame-Options "DENY" always; + add_header X-Content-Type-Options "nosniff" always; + add_header Referrer-Policy "strict-origin-when-cross-origin" always; + add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; connect-src 'self' https://*.suiscan.xyz https://*.mysten.sui.io;" always; + # Add HSTS when behind TLS termination: + # add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always; + + location / { ... } +} +``` + +--- + +### SEC-10: No Input Length/Size Validation + +**Description:** The `CreateNoteRequest`, `CreateTribeRequest`, and `AddUserToTribeRequest` payloads have no server-side length limits. For example, notes.rs only checks `content.trim().is_empty()` but allows arbitrarily large content. + +**Impact:** An attacker could submit extremely large payloads, causing excessive database storage and potentially slowing queries (resource exhaustion / DoS). + +**Guidance/Fix:** + +```rust +if payload.content.len() > 10_000 { + return (StatusCode::BAD_REQUEST, "Note content exceeds maximum length").into_response(); +} +``` + +--- + +### SEC-11: GitHub Actions Not SHA-Pinned + +**Description:** The CI/CD workflows use tag-based references for third-party actions (e.g., `actions/checkout@v6`, `oven-sh/setup-bun@v2`). One exception: `jlumbroso/free-disk-space` is correctly SHA-pinned in ci.yml. + +**Impact:** If a third-party GitHub Action is compromised (tag overwrite), malicious code could execute in the CI runner, stealing secrets or injecting backdoors (supply chain attack per CISA guidance on CI/CD security). + +**Guidance/Fix:** Pin all non-GitHub-official actions to commit SHAs: + +```yaml +- uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683 # v6 +- uses: oven-sh/setup-bun@735343b667d3e6a283f1b0f4a75e9d9afc0d7777 # v2 +``` + +Add a tool like Dependabot or Renovate to track SHA updates. + +--- + +### SEC-12: `is_super_admin` JWT Claim Not Revalidated in `AuthenticatedUser` + +**Description:** At auth.rs, the `AuthenticatedUser` extractor trusts the `is_super_admin` claim from the JWT without re-checking the environment variable. While the `RequireSuperAdmin` middleware correctly re-validates, the `is_super_admin` field on `AuthenticatedUser` is surfaced to the frontend via `get_me`. + +**Impact:** If an admin is removed from `SUPER_ADMIN_DISCORD_IDS`, their existing JWT (valid up to 24h) will still show `isSuperAdmin: true` in the `/api/me` response. The frontend may display the admin panel link, though actual admin API calls will fail (protected by `RequireSuperAdmin`). This is a confusing UX inconsistency and minor information leak. + +**Guidance/Fix:** Either shorten JWT expiration for super admins, re-check the env var in `get_me`, or remove `is_super_admin` from JWT claims entirely and always derive it from the environment variable: + +```rust +// In get_me handler: +let super_admin_ids_str = std::env::var("SUPER_ADMIN_DISCORD_IDS").unwrap_or_default(); +let super_admin_ids: Vec<&str> = super_admin_ids_str.split(',').map(|s| s.trim()).collect(); +let is_super_admin = super_admin_ids.contains(&user.discord_id.as_str()); +``` + +--- + +## 3.
