CVE-2021-33324Network attack vector

Authenticated page disclosure via missing permission check

Published Aug 3, 2021 · Updated Aug 3, 2024

Improper authorization in Liferay's Layout module allows remote authenticated users to view pages hidden by access controls. In Liferay Portal 7.1.0 through 7.3.1, Liferay DXP 7.1 before fix pack 20, and DXP 7.2 before fix pack 5, the page-administration path fails to enforce each page's view permission before rendering it. A valid account with access to site page administration is required, and exploitation discloses only pages that the account is not authorized to view.
