CVE-2020-10714

A flaw was found in WildFly Elytron version 1.11.3.Final and before. When using WildFly Elytron FORM authentication with a session ID in the URL, an attacker could perform a session fixation attack. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Weakness

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

Affected Software

Extended Description

Such a scenario is commonly observed when:

In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
