The most technically simple method we can use is to sniff someone's cookie.

Being aware of the security precautions the frameworks you use take is important, and we plan on detailing out more of our approaches to security in the future.

Here firstly we identified if user was authenticated before using Security Context Context()Authentication().

Of course, this has the downside that all traffic must be served via HTTPS, which increases processing overhead, network traffic, and makes caches much less effective.

For many sites that deal with sensitive information, this is an acceptable cost, but is there a better way?

If he/she was, then we called Security Context Logout Handler().logout(request, response, auth) to logout user properly. You don’t need anything else anywhere in your application to handle logout.

Notice that you don’t even need to do anything special in your spring configuration(xml or annotation based), shown below just for information: package com.websystique.springsecurity.configuration; import org.springframework.beans.factory.annotation.

Now that we've seen a few different ways to steal a session id, we can talk about some techniques to secure a website. This is a viable strategy and is used by many popular websites.

For example, Facebook will now only serve you pages via HTTPS, which prevents any fixation from happening as all traffic is encrypted (including the session id) and cannot be decoded by a third party.

Basically, you listen to unencrypted network traffic for other users, and watch for the session id to be transmitted.

Once it is, you have immediate access to it and can impersonate the user. A harder attack to pull off requires a couple of extra vulnerabilities to be identified on the website.

It wasn't the intended way to beat the level, but it worked nonetheless.
