### jwtXploiter
A tool to test security of JSON Web Tokens.
Test a JWT against all known CVEs;
- Tamper with the token payload: changes claims and subclaims values.
- Exploit known vulnerable header claims (kid, jku, x5u)
- Verify a token
- Retrieve the public key of your target's ssl connection and try to use it in a key confusion attack with one option only
- All JWAs supported
- Generates a JWK and insert it in the token header
- And much, much more!

### Who this tool is written for?
+ Web Application Penetration Tester / Bug Bounty Hunters
- This tool has been written with the aim of become a key part of pentesters toolkit.
+ Devs who need to test the secuirty of JWTs used in their applications
+ CTF Players
+ Not For Students
- Since this tool automates lot of stuff, without force the user to know what's happening under the hood, it won't
help you to understand the vulnerabilities it exploits.
### To Know
- For attacks that generates a jwks file, you could find it in the current working directory. Remeber to deletes such files
in order to avoid conflicts.
- For jku/x5u injection that needs to merge two urls (the server vulnerable url and your one), the HERE keyword is required.
- For redirect attacks the keyword should replace the redirect url, e.g.
- http://app.com/foo?redirect=bar&some=thing --> http://app.com/foo?redirect=HERE&some=thing
- For jku/x5u injections via HTTP header injection attacks, the HERE keyword sould be appended to the vulnerable parameter,
without replacing its value, e.g.
- http://app.com/foo?param=value --> http://app.com/foo?param=valueHERE
- Also, in such cases, be sure to pass the server url and your one as comma separated values.
- '/.well-known/jwks.json' is automatically appended to your url in jku/x5u attacks. So make sure to place the jwks file under
this path on your server.
- If you don't want that happen, use the --manual option, but this option is compatible only with --jku-basic and --x5u-basic
so, you will need to manually craft the url and pass it to those options, even for attacks that exploit Open Redirect or
HTTP header injection.
- Look at the wiki for a detailed documentation.
