AI-suggested
European organizations should immediately audit their Liferay Portal and DXP deployments to identify sites with default “Open” membership settings. Administrators should change the default membership type for newly created sites from “Open” to more restrictive options such as “Private” or “Restricted,” requiring explicit approval for membership. Implement strict user registration controls and verification processes to limit the creation of unauthorized accounts. Employ role-based access controls (RBAC) and regularly review site membership lists to detect and remove unauthorized users. Monitor portal logs for unusual membership changes or content modifications. Where possible, apply vendor patches or updates once released. Additionally, consider deploying web application firewalls (WAFs) with custom rules to detect anomalous site membership activities. Conduct user awareness training to highlight risks associated with open membership policies. Finally, integrate vulnerability scanning and configuration management tools to continuously detect and remediate insecure default settings in Liferay environments.
Description
In Liferay Portal 7.1.0 through 7.4.3.111, and Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions, the default membership type of a newly created site is “Open” which allows any registered users to become a member of the site. A remote attacker with site membership can potentially view, add or edit content on the site.
