Bypass Rate Limits in Web Applications and API's.

— What is Rate Limit

Rate limiting is a process to limiting the number of request an user can make to a web server in an span of time.

#web #api #rate #limit #bypass #bugbounty #bugbountytips #infosec #cybersecurity
This can be achieved by implementing IP based, Session Based rate limits on web server.

—Where to Look for Rate Limit Bugs

Place like :
— Login/Signup pages
— Register Pages
— 2FA codes
— Confirmation Codes
...and any other request which if bruteforce will allow attacker to achieve anything malicious should be check for "No Rate Limit" issue.

[Bypass 1] - Using Null Chars
