XSS Tip : Target error parameters on shopping cart pages. ๐
- Find the checkout URL
- fuzz for error, msg, err, ...
- Test for reflection : ?error=XSS&msg=XSS&err=XSS....
Often, these parameters bypass standard encoding.
#BugHunting#HackingTips#XSS
On SPA apps (React/Vue/Angular), use Burp Match & Replace to swap all "false" to "true" in JSON responses.
The result ? Hidden admin panels, debug modes, and restricted UI features can appear. ๐
Don't just test the API, explore the UI! ๐ก๏ธ

๐ฅ XSS Tip: Raw HTML response vs Browser DOM
When a XSS payload is reflected and filtered in a HTML response, always verify it in the DOM as well.
Why? In the raw HTML response, your payload might look safely filtered or encoded. However, once it reaches the DOM, it can still execute due to JavaScript processing (client-side rendering).
Don't just trust the raw bytes in Burp โ trust the DOM ๐!

๐ฅ XSS Tip: Unicode Normalization
Don't give up if <, >, " or ' are filtered ! Many apps normalize Unicode after the WAF/security layer.
Some bypass variants (URL-encoded):
๐น < โ %EF%BC%9C
๐น > โ %EF%BC%9E
๐น " โ %EF%BC%A2
๐น ' โ %EF%BC%87
๐น ` โ %EF%BD%80
For example, inject %EF%BC%9Cscript%EF%BC%9E and check if it reflects as <script> in the DOM.

๐ก๏ธ #XSS Tip :
1๏ธโฃ Spot a data-.... tag in the HTML response.
2๏ธโฃExample: <div data-user-id="123">
3๏ธโฃ Test the prefix as a new GET/POST param: ?user=REFLECTED or userId=REFLECTED
4๏ธโฃ Result: <div data-user-id="REFLECTED">
The prefix is often a hidden reflected param name ! ๐ฅ

I think I've found 70% of my XSS vulnerabilities automatically in BBP with a tool. I think it can be useful for bb hunters and pentesters. I'll give details of the tool and a test phase in the next few days.
Whatโs your goto method to find XSS quickly?
Stay tuned ๐
1/6 Tired of manually testing every parameter hoping to find an XSS?
Yeah us too. It's time-consuming, repetitive, and let's be honest, not the most exciting part of the job.
So we built a Burp Suite extension @onetestfr to automate the entire process (Caido coming soon).
Rewarded for multiple XSS in bug bounty ๐ฐFound them with Onetest โ the upcoming tool made for XSS hunters. Itโs clean, fast, and built to find what others miss. Coming soon ๐#bugbounty#xss#Onetest#infosec
๐ก Bug bounty - XSS Tip : Found a vulnerable GET parameter? Always check its context in the response! ๐
Example:
If the GET param name is vulnerable and shows up in <script> _cq.name = '[INJECTION]'..., test all param names after _cq. across every response ! You could discover more hidden XSS! ๐๐ฅ

๐ก XSS Tip : If you find a vulnerable parameter on your target, test all parameters with a similar name structure!
Example:
Vulnerable param found : "user_name"
Test all params starting with "user_" ! ๐ฏ๐ฅ
