Background

TYPO3 is an open-source content management system (CMS) used for building and managing websites. It provides a wide range of features and functionalities for creating dynamic web applications. However, versions before 4.1.14, 4.2.x before 4.2.13, 4.3.x before 4.3.4, and 4.4.x before 4.4.1 are susceptible to a session fixation attack. This vulnerability allows remote attackers to hijack a victim's session, potentially leading to unauthorized access and data manipulation.

Vulnerability Detail

The session fixation vulnerability in TYPO3 enables attackers to manipulate session identifiers, allowing them to impersonate legitimate users. By fixing a session identifier before authentication, an attacker can force a victim to use a known session ID, granting unauthorized access to their account. This can lead to various malicious activities, such as stealing sensitive information, modifying user settings, or performing actions on behalf of the victim.
