If an attacker submit multiple input parameters (query string, post data, cookies,etc.) of the same name, the application may react in unexpected ways and open up new avenues of server-side and client-side exploitation.This is the premise of
-
HTTP Parameter Pollution
-
Session Splitting
-
Parameter Damage
-
Parameter Busting
To solve this question, the user needs to understand the concept of security vulnerabilities related to web applications.
The correct answer is A. HTTP Parameter Pollution.
Explanation:
HTTP Parameter Pollution (HPP) is a security vulnerability that arises when an attacker submits multiple input parameters of the same name to a web application. This can lead to unexpected behaviors on the server-side and client-side, which can then be exploited by attackers to achieve their goals.
Option B, Session Splitting, is not related to the given premise. Session Splitting is a technique used to distribute user sessions across multiple servers to improve performance and scalability.
Option C, Parameter Damage, is not a commonly used term in the field of web application security. It is not related to the given premise.
Option D, Parameter Busting, is not a commonly used term in the field of web application security. It is not related to the given premise.
Therefore, the correct answer is:
The Answer is: A. HTTP Parameter Pollution.
HTTP Parameter Pollution (HPP) is the attack where multiple parameters sharing the same name are submitted in a request (query string, POST body, cookies), causing the web server, application framework, or backend components to disagree on which value to use — different layers may pick the first, last, or concatenate values, leading to filter bypass, access-control bypass, or injection. This exactly matches the scenario described. "Session Splitting," "Parameter Damage," and "Parameter Busting" are not established security terms for this technique — they're plausible-sounding distractors.
