Background

Magnolia CMS is an open-source content management system that allows users to create, manage, and publish digital content. It is built on top of the Java platform and provides a range of features for website development and content authoring. The Magnolia CMS version 6.2.3 and below are affected by a vulnerability that allows attackers to exploit an Open Redirect vulnerability and Cross-Site Request Forgery (CSRF) on the Login page. This vulnerability can be used to perform brute force attacks and exfiltrate users' credentials.

Vulnerability Detail

The impact of this vulnerability can be severe, as it compromises the security and privacy of users' accounts and potentially exposes sensitive data.
