All language subtitles for 11. No Rate Limit Bypass Report Breakdown 2

Hello everyone.
1

So in this video we are going to see how we can achieve No-Rate limit protection bypass.
2

Number two.
3

So in this video we will see how we can bypass No-Rate limit using x forwarded host header into any request.
4

So for this we are going to see a report right now to understand this better of bypassing rate limit
5

protection by spoofing originating IP.
6

So let's see what the user was able to do.
7

The first screenshot They blocked my IP as you can see this user was performing an action in which there
8

is a WAF which is blocking as you can see 403 forbidden now trying to host header injection which means
9

modifying the host from the www.example.com to www.xyz.com
10

adding x forwarded host hacker.com but still no success.
11

Now trying for X forwarded for option to spoof originating IP address.
12

So we are going to give a random IP address in X forwarded for still no success.
13

Now trying with X forwarded for IP header into the request twice two times instead of one thing and
14

you can see we were successfully able to bypass this No-Rate limit protection because the application
15

is giving 200 ok right now.
16

So what is the lesson learned the lesson learned is that you can bypass no rate limit by applying or
17

digital header it like X forwarded for or X forwarded in the request X for x-forwarded host in the request.
18

So let's get back to the presentation and let us No-Rate limit by ad adding some specific headers
19

so you can add headers with the request like x-originating IP and you can give any random IP X
20

forwarded for that we already saw into the report X remote IP, X remote address, x client IP X host and
21

X forwarded host we already saw X forwarded host and X forwarded for through which the user was able to bypass
22

the no rate limit.
23

So this is one of the way in the bypass number two in which you can bypass the no rate limit protection
24

so the first one understood we understood the second one also third is remote IP remote address client
25

IP X host and X forwarded host so practical time.
26

So let's see what we can achieve through this.
27

And I have written a small script to explain this to you guys.
28

So let me just open the script.
29

nano check.py
30

So this is a Python script which basically add these headers the headers that we understood into the
31

slide and sent the request to the specific target you want to send to.
32

Okay.
33

So you have to use like this python check IP domain name.
34

http or https
35

And you have to send the request.
36

So let's see how to use this.
37

I already run it couple of times so you can see from your python check.py www.udemy.com
38

HTTPS as you can see for the first header we added the status code was 200 response-size was this.
39

This is nothing but the response length x-forwarded host a response and changed remote IP length change
40

at a remote address length changed client IP length remains the same X host Length change forwarded host
41

length remains the same X this one and this one.
42

So basically in this we can see the application that is udemy.com behaves in a different manner
43

when different different headers are been sent.
44

So yeah we can try for no rate limit by adding a new header each time as we can see there is some change
45

into the response.
46

Similarly I tried on Instagram and Instagram.
47

Also we were able to see changes into the into the response by adding new headers.
48

Similarly I tried on no broker but this time the response was same for everything because they are not
49

parsing anything like this and no rate limit is fixed on their website and which cannot be bypassed
50

anymore.
51

99 acers is still the same on Tinder.com still the same.
52

We are not able to perform no rate limit by bypassing by adding any of the headers I will attach this
53

code in the description and you guys can utilize this for your testing.
54

I hope you guys understood.
55

Thank you so much.
