D.
Parameter Manipulation

Explanation:
Manipulating the data sent between the browser and the web application to an attacker’s advantage has long been a simple but effective way to make applications do things in a way the user often shouldn’t be able to. In a badly designed and developed web application, malicious users can modify things like prices in web carts, session tokens or values stored in cookies and even HTTP headers. In this case the user has elevated his rights.
