        Vulnerability
        • cwe
        • spring

        An attacker may trick a user into using a predetermined session identifier. Consequently, this attacker can gain unauthorized access and impersonate the user’s session. This kind of attack is called session fixation, and protections against it should not be disabled.

        Why is this an issue?

        How can I fix it?

        More Info

        Session fixation attacks take advantage of the way web applications manage session identifiers. Here’s how a session fixation attack typically works:

        • When a user visits a website or logs in, a session is created for them.
        • This session is assigned a unique session identifier, stored in a cookie, in local storage, or through URL parameters.
        • In a session fixation attack, an attacker tricks a user into using a predetermined session identifier controlled by the attacker. For example, the attacker sends the victim an email containing a link with this predetermined session identifier.
        • When the victim clicks on the link, the web application does not create a new session identifier but uses this identifier known to the attacker.
        • At this point, the attacker can hijack and impersonate the victim’s session.

        What is the potential impact?

        Session fixation attacks pose a significant security risk to web applications and their users. By exploiting this vulnerability, attackers can gain unauthorized access to user sessions, potentially leading to various malicious activities. Some of the most relevant scenarios are the following:

        Impersonation

        Once an attacker successfully fixes a session identifier, they can impersonate the victim and gain access to their account without providing valid credentials. This can result in unauthorized actions, such as modifying personal information, making unauthorized transactions, or even performing malicious activities on behalf of the victim. An attacker can also manipulate the victim into performing actions they wouldn’t normally do, such as revealing sensitive information or conducting financial transactions on the attacker’s behalf.

        Data Breach

        If an attacker gains access to a user’s session, they may also gain access to sensitive data associated with that session. This can include personal information, financial details, or any other confidential data that the user has access to within the application. The compromised data can be used for identity theft, financial fraud, or other malicious purposes.

        Privilege Escalation

        In some cases, session fixation attacks can be used to escalate privileges within a web application. By fixing a session identifier with higher privileges, an attacker can bypass access controls and gain administrative or privileged access to the application. This can lead to unauthorized modifications, data manipulation, or even complete compromise of the application and its underlying systems.
