## About the Challenge
|
|
We got a websites that can make requests to other websites and display the response
|
|
|
|
|
|
|
|
We need to access `/hehe.txt` by using that feature. However there is a limit of characters that we can input into that form
|
|
|
|
|
|
|
|
## How to Solve?
|
|
In order to read the flag, we need to access the website internally and access the `/hehe.txt` endpoint
|
|
|
|
At first, I inputted `127.0.0.1/hehe.txt` but the response is `Oh no no, url is too long I can't handle it`. And then I and found this [payload](https://github.com/swisskyrepo/PayloadsAllTheThings/blob/master/Server%20Side%20Request%20Forgery/README.md)
|
|
|
|
|
|
|
|
So, my final payload was:
|
|
```
|
|
0.0.0.0/hehe.txt
|
|
```
|
|
|
|
|
|
|
|
```
