Bypass Rate Limits on authentication endpoints like a pro………!

In the world of ethical hacking, mastering the art of bypassing rate limits can be a game-changer and help you get more bounties. Let’s explore some straightforward techniques that can be employed to navigate these constraints seamlessly.

When faced with rate limitations, headers can become your secret weapon. Introduce the following headers just under the Host Header in your request:

X-Forwarded-For: IPX-Forwarded-Host: IPX-Client-IP: IPX-Remote-IP: IPX-Remote-Addr: IPX-Host: IP

Change the IP whenever your request faces a blockade.

A helpful tip: experimenting with multiple headers might just do the trick! The rate limit on authentication actions can be bypassed by adding the double X-Forwarded-For header to the request one with the value 127.0.0.1

X-Forwarded-For:

X-Forwarded-For: 127.0.0.1

CAPTCHAs are familiar roadblocks during website testing. Here are some savvy ways to bypass them:

Remove the CAPTCHA parameter from the request body.Add a string of the same length as the parameter.Keep the intercept on and send the request to Intruder for unexpected results.

The key is to stay creative in your approach.

Playing with characters can be surprisingly effective. Consider these tricks:

Add a Null Byte (%00) at the end of the email to potentially bypass rate limits.Try a space character after an email (not encoded).Some common characters that work wonders: %0d, %2e, %09, %20.

Experiment with these characters to find the sweet spot that bypasses the limitations in your specific scenario.

When faced with rate limits, exploring alternative login or forgot password endpoints can open unexpected doors. These paths might be concealed in mobile apps or legacy JavaScript files. Look beyond the obvious routes; sometimes, the backdoors are where you least expect them.

Unveiling a secret weapon,a bonus trick. Rate-limiting rules often revolve around specific endpoint routes. By strategically modifying the route with /. or /.., the request may cease to match the rate-limiting criteria, creating an opportunity for additional requests.

Here’s how it works:

Modification Technique: Add /. or /.. to the endpoint route.Normalization Confusion: The server might remove these modifications during normalization.Effectively, /path and /path/.. could be treated as the same request post-normalization.

This manipulation can lead to bypassing rate limits.
