DEFINE SESSION HIGH HOW TO

spring security session fixation ensures the attacker cannot use the old session to gain access to the application.On Wednesday, the European Parliament adopted its negotiating position on the Artificial Intelligence (AI) Act with 499 votes in favour, 28 against and 93 abstentions ahead of talks with EU member states on the final shape of the law. Protection Using Spring Security Session Fixationīy default, Spring security protects the session fixation attackby creating a new session or otherwise changing the session ID when a user logs in. This is just an example, but remember in a typical Java based web application, you can pass the session id using the following options:Ģ. Once the session is obtained, they can redirect the customer to login page with their session id. They need to ensure that no invalid session id is being used, also the session can be timed out before they can use it. Application sessions id are time bound.There are few additional challenges for the attackers in this approach. If the application only allows the session id generated by the application, it will add a step for the attacker to get a valid session id from the application before they can trick the victim to do a login using their session id.

If this is the case, it’s easy for the attacker to simply generate a random ID and pass it with the login request. There are many applications which can accept not only the session id but any other ID provided by the client. There are multiple variation of this attack, let’s check few of them: 1.1 Random SID With the same session id, malicious attacker can use the same session id to get authenticated passing no username or password.

Keep in mind Spring security authentication rely on the session id to check if the session is authenticated or not. This is not a problem if the user is not logged in, but it will become serious if the application will continue to use the same session id after user is authenticated.

Attackers can now use the same session id to access the secure area of the application, as this session is already authenticated by the application.

Victim is authenticated with the same session id (we will talk about the same session ID later).

They trick victim to authenticate, where attackers will pass the same session id in the authentication request.

Attackers get a valid session id from our application.

Here is how a high level attacks look like: Session fixation is an attack and can be done in multiple ways. Understanding Session Fixation Attacksīefore we get into details of spring security session fixation and how the security can help us fix this potential issue, it’s important that we clearly understand the problem.

In session fixation, the attacker will first get a valid session from the application and then redirect the user to the login page to let you login so they can use the session to login to application.ġ.In session hijacking, the attacker will steal your authenticated session to get access to the application.

Keep in mind the following important point for better understanding. Think of session fixation as kind of vulnerability where attacker will trick you to login to application and then use your session to get access to the same site. The session fixation is a very common and most frequent type of attack where it is possible for a malicious attacker to create a session by accessing a site, then persuade another user to log in with the same session (by sending them a link containing the session identifier as a parameter, for example).

In this article of our spring security course, we will look at the Spring Security session fixation and how to prevent the session hijack in our spring application.
