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 .

Exploit known header claims (kid, jku, x5u)

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!

or, if previous is installed on your machine

+ With pip:

+ With deb:

+ Cloing the repo:

N.B. python3-pip package is required to install dependencies, be sure to have it installed.

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 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 ser url and your one), the HERE keyword is required.

For redirect attacks the keyword should replace the redirect url, e.g.

- -->

For jku/x5u injections via HTTP header injection attacks, the HERE keyword sould be appended to the parameter,

without replacing its value, e.g.
- -->

Also, in such cases, be sure to pass the server url and your one as comma separated .

'/.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.
