## Module 6:Exploiting Application-Based vulnerabilities — part 2

## Exploiting Authentication-Based Vulnerabilities

An attacker can bypass authentication in vulnerable systems by using several methods. The following are the most common ways to take advantage of authentication-based vulnerabilities in an affected system:

* **Credential brute forcing**
* **Session hijacking — A** web session is a sequence of HTTP request and response transactions between a web client and a server. A large number of web application keep track of information about each user for the duration of the web transactions. Several web application have the ability to establish variables such as access rights and localization settings. These variables apply to each and every interaction a user has with the web application for the duration of the session. Once an authenticated session has been established, the session ID is temporarily equivalent to the strongest authentication method used by the application, such as usern
