CVE-2024-29023Network attack vector

Session hijacking via exposed session search tokens

Published Apr 12, 2024 · Updated Aug 2, 2024

Information exposure in Xibo CMS 1.8.0 through 3.3.9 and 4.0.0 through 4.0.8 allows remote authenticated users to hijack sessions. SessionFactory::query hydrates the session_id column into each session object returned by the session-search API, exposing reusable tokens until the patched code excludes that property before serialization. Access to the Sessions page or super-administrator privileges is required, after which a disclosed token grants the victim session's permissions.
