Hunt Microsoft SharePoint Server (2013/2016/2019/Subscription Edition) on-prem farms — anonymous endpoint enumeration, version disclosure, legacy SOAP login bypass (Authentication.asmx), ToolShell precondition chain (CVE-2025-53770), SafeControl reflection enumeration via Picker.aspx, NTLM Type-2 AD topology disclosure, custom-branding module discovery, EoL farm permanent-CVE-window exploitation, FormDigest anonymous issuance, file-extension blocklist NOT-an-oracle pattern, custom-zone Forms auth bridging on-prem AD.

## Crown Jewel Targets SharePoint Server (on-prem) is one of the richest enterprise attack surfaces in 2025-2026 bug bounty / red-team work. Three forces converge: 1. **End-of-life unpatched code paths.** SharePoint Server 2013 reached extended-support EoL on 2023-04-11 (final build `15.0.5545.1000` / KB5002381). Every SharePoint CVE published after that date is **permanently unpatched** on SP2013 farms. SP2016 reaches EoL 2026-07-14; SP2019 reaches EoL 2026-07-14 (next 2 months as of May 2026); only SP Subscription Edition is currently in active support. 2. **CVE-2025-53770 / 53771 "ToolShell"** — July 2025 emergency-out-of-band patch chain for SPE / SP2019 / SP2016. The vulnerable code path (anonymous `/_layouts/15/ToolPane.aspx?DisplayMode=Edit` + anonymous `__REQUESTDIGEST` + unencrypted ViewState) is present in **SP2013 too** and will never receive a fix. 3. **Custom branded login pages forget legacy SOAP login.** `/_vti_bin/Authentication.asmx` with the `Login` SOAP op is the SharePoint equivalent of WordPress XMLRPC bypass — accepts native Forms credentials anonymously with no rate limit on most farms even when the branded UI has lockout. **Highest-value SharePoint targets:** - **SP2013 farms still on the public internet** — every CVE since April 2023 is unpatched. Critical-severity findings. - **Dealer / partner / supplier portals** built on SharePoint by enterprise integrators (German VW group, a enterprise system integrator, etc.) — high-impact business data, of...

hunt-api-misconfig

Hunt API security misconfiguration — mass assignment, JWT attacks, prototype pollution, CORS, HTTP verb tampering. Mass assignment: send {is_admin:true, role:admin, verified:true} on profile/account/reset endpoints — server blindly applies. JWT: alg=none, weak HMAC bruteforce, kid path traversal, JWK injection, token confusion. Prototype pollution: __proto__ injection in JSON merge / Object.assign / lodash _.merge → polluted prototype reaches sink (RCE in Node, XSS in browser). CORS: wildcard with credentials, null origin, regex with subdomain takeover, postMessage origin checks. HTTP verb: GET-bypass-CSRF, X-HTTP-Method-Override, TRACE enabled. Detection: API responses with extra fields, JWTs in headers (decode at jwt.io), CORS preflight responses. Use when hunting API misconfigs, JWT flaws, mass-assignment, prototype pollution, CORS bypasses.
