Broken Authentication by removing auth token

Broken Authentication by removing auth token

API doesn't validate the authenticity of token. Attacker can remove the auth token and access the endpoint.

Broken User Authentication (BUA)

"The endpoint appears to be vulnerable to broken authentication attack. The original request was replayed by removing victim's <b>auth</b> token. The server responded with 2XX success codes.<br>" "<b>Background:</b> Authentication is the process of attempting to verify the digital identity of the sender of a communication. Testing the authentication schema means understanding how the authentication process works and using that information to circumvent the authentication mechanism. While most applications require authentication to gain access to private information or to execute tasks, not every authentication method is able to provide adequate security. Negligence, ignorance, or simple understatement of security threats often result in authentication schemes that can be bypassed by simply skipping the log in page and directly calling an internal page that is supposed to be accessed only after authentication has been performed."

Impact of the vulnerability

Impact of the vulnerability

Broken User authentication is a serious vulnerability. Attackers can gain control to other users’ accounts in the system, read their personal data, and perform sensitive actions on their behalf, like money transactions and sending personal messages.

How this template works

APIs Selection

The template includes a filter for the response code, specifically selecting APIs where the response code is greater than or equal to 200 and less than 300. This filter ensures that only APIs with successful responses are considered for further testing.

Execute request

The template specifies a single request to be executed. In this case, the request includes a step to remove the authentication header. This step simulates an attacker removing the authentication token to exploit the broken authentication vulnerability.

Validation

The template includes a validation step to check the response code of the executed request. Similar to the API selection filters, the validation ensures that the response code is within the range of 200 to 300, indicating a successful response. This confirms that the vulnerability was successfully exploited and the server responded with a 2XX success code.
