Bypass captcha based protection by adding headers

Bypass captcha based protection by adding headers

Attackers can circumvent captcha protection by adding headers like x-forwarded-for, compromising the system's security.

Lack of Resources & Rate Limiting (RL)

Business Logic

"The inclusion of specific headers, such as x-forwarded-for, empowers attackers to bypass captcha protection mechanisms, posing a significant threat to the system's security." "By manipulating these headers, malicious actors can undermine the intended security measures, potentially leading to data breaches and other detrimental consequences that compromise the overall system integrity."

How this template works

APIs Selection

The template uses API selection filters to specify the criteria for selecting the API requests to be executed. 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" and extracts the value of the "captcha_key" parameter.

Execute request

The template defines a single request to be executed. It includes deleting the "captcha_key" from both the request body and query parameters, and adding a header "x-forwarded-for" with the value "127.0.0.1". This is done to bypass captcha protection by manipulating headers.

Validation

After executing the request, the template validates 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. These validation criteria ensure that the request was successful and the response contains the expected data.
