Hello Folks, i want to tell my story of this type of XSS.
Why this payload work?
…In my case, i was in front of an application that my payload was closed by Unicode Character.
This Payload was Blocked:
I This case i tryied to use another svg and the response was:
Unexpectedly, I noticed that it has moved one position. So:
In this case we notice that we have escaped from unicode character. And again with the slash:
\u01237\/ ----> \/\u01237\/\ ----> /\u01237\/ ----> /
And again bypass:
On\u01234\load ----> On\u01234\+OnLoAd ----> onload
We can use this payload for bypass CloudFlare too with default configuration:
(Note this is an example, but you can notice that the payload bypass cloudflare).
I release you another good payload that bypass filters :) Maded by me.
|| Good luck everyone with hunting ||
