Possible DOS attack by Pagination misconfiguration

Possible DOS attack by Pagination misconfiguration

Quite often, APIs do not impose any restrictions on the size or number of resources that can be requested by the user.

Lack of Resources & Rate Limiting (RL)

Such vulnerabilities arise when there is no max limit imposed on the number of resources returned. Typically, the number of objects to be returned is provided by a parameter in the API call. An attacker can set it as a large number.

Impact of the vulnerability

Impact of the vulnerability

This can impact the API server performance, leading to Denial of Service (DoS). It also leaves the door open to authentication flaws such as brute force.

How this template works

APIs Selection

The template uses query parameters to filter the API requests. It looks for query parameters with keys that match certain regular expressions (such as "limit", "size", or "page") and extracts their corresponding values. These values are then stored as variables for later use.

Execute request

The template modifies the query parameter "limitKey" by appending a "0" to its value. This is done using the "modify_query_param" action. The modified request is then sent to the API server.

Validation

The template validates the response received from the API server. It checks that the response code is between 200 and 299 (indicating a successful response). Additionally, it compares the length of the response payload to the original length stored in the "original_length" variable. The validation passes if the response payload length is greater than the original length. Note: The template is designed to detect and mitigate the potential DOS attack caused by pagination misconfiguration in APIs. It ensures that the API server imposes a limit on the number of resources returned, preventing performance issues and potential authentication flaws.
