Corsy
CORS Misconfiguration Scanner
### Introduction
Corsy is a lightweight program that scans for all known misconfigurations in CORS implementations.
### Requirements
Corsy only works with `Python 3` and has the following depencies:
- `tld`
- `requests`
To install these dependencies, navigate to Corsy directory and execute `pip3 install -r requirements.txt`
### Usage
Using Corsy is pretty simple
`python3 corsy.py -u https://example.com`
##### Scan URLs from a file
`python3 corsy.py -i /path/urls.txt`
##### Number of threads
`python3 corsy.py -u https://example.com -t 20`
##### Delay between requests
`python3 corsy.py -u https://example.com -d 2`
##### Export results to JSON
`python3 corsy.py -i /path/urls.txt -o /path/output.json`
##### Custom HTTP headers
`python3 corsy.py -u https://example.com --headers "User-Agent: GoogleBot\nCookie: SESSION=Hacked"`
##### Skip printing tips
`-q` can be used to skip printing of `description`, `severity`, `exploitation` fields in the output.
