High-value targets include:\n\n- **SSO/SAML implementations** at enterprise SaaS companies (Slack, Okta, OneLogin integrations) — payouts regularly in the $5K–$25K+ range\n- **Admin panels and partner/internal portals** — subdomain-separated admin surfaces like `partners.shopify.com`, `admin.company.com`\n- **Third-party auth plugin integrations** — WordPress plugins (OneLogin, WP-SAML-Auth), Drupal SSO modules, any CMS with pluggable auth\n- **XMLRPC endpoints** on WordPress — often forgotten, bypasses standard WP auth flows entirely\n- **OAuth callback flows** — state parameter mishandling, redirect_uri mismatches\n- **API authentication layers** — especially where auth was bolted on after the fact\n\n**Asset priority:** Targets with federated identity (SAML, OAuth, OIDC) connected to large user populations. Partner/reseller portals are particularly juicy because they often have elevated permissions and less security scrutiny than the main product.\n\n---\n\n### SSH certificate-authority trust forgery (Git-hosting / enterprise platforms)\nWhen an org or instance registers an SSH certificate authority, cert `principals` may not be bound server-side to the requesting identity — a member can mint a cert asserting another user's principal and authenticate as them (e.g. modify another user's resource given only its URL). Add SSH-CA trust to the auth-surface list on Git-hosting targets; niche/platform-specific. Disclosed: reports/1901040.\n\n## Attack Surface Signals\n\n**URL patterns to hunt:**\n```\n/xmlrpc.php\n/wp-login.php\n/saml/\n/sso/\n/auth/saml/callback\n/oauth/callback\n/partners.*\n/admin.*\n/?wc-api=\n/api/v*/auth\n/login?redirect=\n/accounts/login\n```\n\n**Response headers signaling SSO:**\n```\nX-Frame-Options: SAMEORIGIN (common on SSO portals)\nSet-Cookie: SAMLResponse=\nLocation: https://idp.company.com/saml\nWWW-Authenticate: Bearer realm=\"partners\"\n```\n\n**JS patterns indicating federated auth:**\n```javascript\n// Look for in page source\nsamlRequest\nRelayState\nSAMLResponse\nonelogin\nshibboleth\nokta\npassport.js authenticate\n```\n\n**Tech stack signals:**\n- WordPress + any SSO plugin → check XMLRPC separately\n- Shopify Partner API exposure → cross-tenant privilege escalation risk\n- Any app advertising \"SSO enabled\" or \"Login with [Enterprise IdP]\"\n- Separate subdomains for admin/partner that share session cookies with main domain\n- Applications using `SimpleSAMLphp`, `ruby-saml`, `python-saml`\n\n**Burp passive scan triggers:**\n- `SAMLResponse` in any POST body\n- `openid_connect` or `id_token` in responses\n- Cookie domains set to `.company.com` (wildcard)\n\n---\n\n## Step-by-Step Hunting Methodology\n\n1. **Map all authentication entry points**\n   - spider the target for every login surface: main login, admin login, API login, partner portal, mobile API endpoints\n   - check `robots.txt`, JS files, and the wayback machine for forgotten endpoints like `/xmlrpc.php`\n\n2. **Identify the auth mechanism per entry point**\n   - Is it forms-based, SAML, OAuth, API key, session token?\n   - For WordPress: always probe `/xmlrpc.php` even if the main login is SSO-protected\n\n3. **Test XMLRPC independently of SSO**\n   - If site uses SSO (e.g., OneLogin), manually POST to `/xmlrpc.php`\n   - XMLRPC uses WordPress-native credentials, not SSO — test with `system.listMethods` first, then `wp.getUsersBlogs`\n\n4. **Enumerate SAML implementation**\n   - Capture a valid SAMLResponse via Burp\n   - Decode the Base64 payload, inspect the XML\n   - Test signature stripping, comment injection, and XML wrapping attacks\n   - Test if SP validates the signature at all (send unsigned assertion)\n\n5. **Test cross-portal session/token reuse**\n   - Log into `partners.shopify.com` type portals\n   - Attempt to use the issued token/cookie against the main admin portal\n   - Look for shared cookie domains, shared JWT secrets, or API tokens that work across contexts\n\n6. **Fuzz auth parameters**\n   - Null/empty passwords, `password[]=array`, SQL in username field\n   - Try `admin`/`admin`, `test`/`test` on staging subdomains\n   - Modify `role`, `is_admin`, `user_type` in JWTs (none algorithm, weak secret)\n\n7. **Check redirect and state parameters**\n   - Does removing `state` from OAuth break anything?\n   - Can you change `redirect_uri` to an open redirect target?\n   - Does the `RelayState` in SAML get validated?\n\n8. **Verify impact by escalating privileges**\n   - Don't stop at login — prove you can access admin functions, other users' data, or sensitive configuration\n   - Screenshot the highest-privilege action you can perform\n\n---\n\n## Legacy-Protocol Matrix (Probe These First on Any Custom-Branded Login)\n\nWhen a target has a custom, branded login UI (e.g. `customlogin.aspx`, `/auth/signin`, `/account/login`), **always probe the platform's legacy protocol endpoints with native credentials** in parallel. These endpoints frequently outlive the custom UI's protections and accept native credentials with NO rate limit, NO MFA challenge, NO CAPTCHA, NO anti-automation. This is the WordPress XMLRPC pattern generalised across CMS / portal / framework stacks.\n\n| Target tech | Legacy endpoint(s) to probe | Native-cred bypass surface |\n|---|---|---|\n| **WordPress** | `/xmlrpc.php` (`system.listMethods`, `wp.getUsersBlogs`, `system.multicall`) | Native WP user/pass; bypasses SSO, MFA, IP-allow rules on `/wp-login.php` |\n| **WordPress (REST)** | `/?rest_route=/wp/v2/users`, `/wp-json/wp/v2/users` | User enumeration anonymously even when login page is hardened |\n| **SharePoint (any version)** | `/_vti_bin/Authentication.asmx` (`Mode` + `Login` SOAP ops) | Native Forms-auth credential; FedAuth cookie returned; no rate limit on this endpoint observed on SP2013 farms — **this is the canonical SP equivalent of the WP XMLRPC bypass** |\n| **SharePoint legacy** | `/_vti_bin/_vti_aut/author.dll`, `/_vti_bin/_vti_adm/admin.dll`, `/_vti_bin/owssvr.dll` | FrontPage RPC; sometimes still wired to credential validators |\n| **SharePoint REST** | `/_api/contextinfo` (POST), `/_api/$metadata` | Anonymous FormDigest issuance; full API surface enumeration |\n| **Atlassian (Jira / Confluence)** | `/rest/auth/1/session` (basic-auth), `/rest/api/2/myself`, legacy `/rest/api/1.0/` | Native credentials accepted on `/rest/auth/1/session` even when Atlassian Crowd / Atlassian Access SSO is enforced on the UI |\n| **Drupal** | `/jsonapi/`, `/user/login?_format=json` | JSON POST endpoint that accepts native passwords; separate from SSO middleware |\n| **Drupal (D7 legacy)** | `/?q=user/login`, `/services/`, `/rest/` | Older REST modules with independent auth |\n| **Joomla** | `/administrator/index.php?option=com_login`, `/api/index.php/v1/users` | Native Joomla credentials accepted on admin entry independent of any front-site SSO |\n| **Exchange / OWA** | `/EWS/Exchange.asmx`, `/Autodiscover/Autodiscover.xml`, `/Microsoft-Server-ActiveSync` | NTLM / Basic; bypasses OWA UI restrictions (MFA, IP-allow). The classic CVE-2020-0688 / CVE-2021-26855 surface |\n| **Citrix NetScaler** | `/vpn/index.html`, `/cgi/login`, `/nf/auth/doAuthentication.do` | Native AD credentials; independent of MFA wrappers |\n| **F5 BIG-IP** | `/mgmt/tm/util/bash`, `/tmui/login.jsp` | Native admin credentials |\n| **Generic ASP.NET app** | `*.asmx?WSDL`, `*.svc?WSDL`, `trace.axd`, `elmah.axd`, `.disco` | Find every web service; many take credentials independently of the WebForms login |\n| **Spring Boot** | `/actuator/*`, `/management/*`, `/api/v1/auth/login`, `/api/v1/swagger-ui` | Actuator endpoints sometimes anonymously enumerable |\n| **Jenkins** | `/jnlpJars/jenkins-cli.jar`, `/script`, `/manage`, `/computer/(master)/script` | API tokens + native auth |\n| **GitLab** | `/api/v3/*` (deprecated but still on old installs), `/api/v4/users`, `/api/v4/projects` | Personal Access Tokens with looser scoping than UI session |\n| **TeamCity** | `/app/rest/users`, `/login.html?username=&password=` (GET-form-login) | Native admin credentials |\n| **Apache Tomcat** | `/manager/html`, `/host-manager/html`, `/manager/text/list` | Native Tomcat realm credentials independent of any front auth |\n| **WebLogic** | `/console/login/LoginForm.jsp`, `/wls-wsat/*` | Native admin |\n| **Oracle EBS / PeopleSoft** | `/OA_HTML/AppsLogin`, `/psp/*/?cmd=login` | Native ERP credentials |\n\n**How to use:**\n1. Identify the tech stack from headers + paths (use `hunt-misc` Attack Surface Signals).\n2. Find the row above that matches.\n3. Probe the legacy endpoint anonymously to confirm it's reachable and not 403/404.\n4. Test with synthetic credentials to confirm it accepts native credential format and returns differential responses (success vs failure).\n5. Verify there is no rate limit, no lockout, no CAPTCHA — burst 10 requests at the same user, confirm uniform timing.\n6. Report as **Critical / High** depending on chain to ATO: an anonymous + unlimited credential brute-force endpoint is consistently Critical on bug-bounty programs.\n\n**Lesson from a authorized engagement:** A an enterprise dealer portal on SharePoint 2013 had a custom branded `customlogin.aspx`. The hunt-auth-bypass skill was loaded but the matrix above did not exist in this document — and the WordPress XMLRPC pattern was not connected to the SharePoint equivalent. `/_vti_bin/Authentication.asmx` was reachable anonymously, accepted unlimited credential attempts with no rate limit and no lockout, and was the highest-impact finding in the engagement. Walking this matrix on the first pass would have surfaced it immediately.\n\n---\n\n## Payload & Detection Patterns\n\n**XMLRPC auth probe (bypasses SSO):**\n```bash\ncurl -s -X POST https://target.com/xmlrpc.php \\\n  -H \"Content-Type: text/xml\" \\\n  -d '<?xml version=\"1.0\"?>\n<methodCall>\n  <methodName>system.listMethods</methodName>\n  <params></params>\n</methodCall>'\n\n# If 200 with method list → XMLRPC is enabled, test auth:\ncurl -s -X POST https://target.com/xmlrpc.php \\\n  -H \"Content-Type: text/xml\" \\\n  -d '<?xml version=\"1.0\"?>\n<methodCall>\n  <methodName>wp.getUsersBlogs</methodName>\n  <params>\n    <param><value><string>admin</string></value></param>\n    <param><value><string>password</string></value></param>\n  </params>\n</methodCall>'\n```\n\n**SAML signature stripping (send unsigned assertion):**\n```python\nimport base64, re\n\n# Decode captured SAMLResponse\nsaml_b64 = \"BASE64_FROM_BURP\"\nsaml_xml = base64.b64decode(saml_b64).decode()\n\n# Strip the Signature element entirely\nstripped = re.sub(r'<ds:Signature.*?</ds:Signature>', '', saml_xml, flags=re.DOTALL)\n\n# Re-encode and submit\nprint(base64.b64encode(stripped.encode()).decode())\n```\n\n**SAML XML comment injection (username confusion):**\n```xml\n<!-- Original NameID -->\n<NameID>attacker@evil.com</NameID>\n\n<!-- Injected ","tagline":"Hunting skill for auth bypass vulnerabilities.
