Replaying request with same captcha

Replaying request with same captcha

The server fails to enforce captcha expiration, allowing users to submit multiple requests using the same captcha value without time restrictions.

Lack of Resources & Rate Limiting (RL)

"Successful replaying of captchas presents a significant problem for companies, as it enables malicious actors to bypass security measures, potentially leading to spamming, data breaches, and reputation damage."

How this template works

APIs Selection

The template includes filters to select API requests based on specific criteria. In this case, it filters requests based on the response code being between 200 and 300, or if the request payload or query parameter contains the word "captcha".

Execute request

The template specifies a single request to be executed. It adds a custom header to the request, specifically the "x-akto-ignore" header with a value of "0".

Validation

The template defines validation criteria for the response. It checks that the response code is between 200 and 300, the percentage match of the response payload is greater than 80%, and the length of the response is greater than 0.
