CVE-2023-42628Public exploitNetwork attack vector

Stored script execution via unencoded child-page content

Published Oct 17, 2023 · Updated Aug 2, 2024

Stored XSS in the Wiki widget in Liferay Portal and DXP allows remote authenticated users to run script in a viewer's browser. The child-page Content field accepts attacker-controlled HTML or JavaScript and renders it unencoded in the parent page's child-page container. The Wiki module must be enabled, the attacker needs permission to add child pages, and a victim must view the parent page; the script executes with that viewer's web-session privileges.
