Invalidating a session Local dates no cc needed

If the session is already invalid, the invalidate() method will throw an Illegal State Exception.

An object can be notified when it is bound to a session or unbound from a session simply by implementing the Http Session Binding Listener interface.

These relationships are defined as Child Of, Parent Of, Member Of and give insight to similar items that may exist at higher and lower levels of abstraction.

In addition, relationships such as Peer Of and Can Also Be are defined to show similar weaknesses that the user may want to explore.

The listings below show possible areas for which the given weakness could appear.

These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms.

For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

In order to exploit the code above, an attacker could first create a session (perhaps by logging into the application) from a public terminal, record the session identifier assigned by the application, and reset the browser to the login page.

As of the release of the Java Servlet API 2.1, Http Session Context has been deprecated.

Now, the session object (embodied within an instance of a class implementing the Http Session interface) is retrieved using Http Servlet Request methods: The invalidate() method, invalidates the current session and unbinds any objects that were previously bound to it.

Even given a vulnerable application, the success of the specific attack described here is dependent on several factors working in the favor of the attacker: access to an unmonitored public terminal, the ability to keep the compromised session active and a victim interested in logging into the vulnerable application on the public terminal.

In most circumstances, the first two challenges are surmountable given a sufficient investment of time.

The biggest challenge an attacker faces in exploiting session fixation vulnerabilities is inducing victims to authenticate against the vulnerable application using a session identifier known to the attacker.
