JWT signing in client side

This test checks for JWT client side signing

Security Misconfiguration (SM)

Impact of the vulnerability

An attacker could potentially exploit the client-side JWT signing vulnerability to manipulate or forge JWT tokens, leading to unauthorized access, privilege escalation, session hijacking, or impersonation attacks. It is crucial to address this vulnerability promptly to protect the integrity and security of the system.

How this template works

APIs Selection

The API selection filters in this template are used to filter requests based on the response payload and URL. The response payload filter checks if the response contains any of the specified JWT signing functions, such as "jwt.sign(", "jose.JWS.createSign(", "JWTSimple.encode(", or "jwt.encode(". The URL filter extracts the URL from the response and assigns it to the variable "urlVar".

Execute request

The execute section of this template specifies that a single request should be executed. The request is modified using the "modify_url" action, which uses the value of the "urlVar" variable to modify the URL of the request.

Validation

The validation section checks if the response payload of the executed request contains any of the specified JWT signing functions. If any of these functions are found in the response payload, the validation is considered successful.
