CVE-2023-40572Public exploitNetwork attack vector

Remote code execution via tokenless page creation

Published Aug 24, 2023 · Updated Oct 2, 2024

Cross-site request forgery in affected XWiki Platform versions allows remote attackers to execute code through the create action. CreateAction.render accepted a page-creation request without validating the form_token parameter, allowing attacker-controlled title content to execute as script. Exploitation requires a crafted image request to be rendered by a user with script or programming right, after which the attacker can compromise the wiki's data and availability.
