CVE-2024-3689Public exploitNetwork attack vector

Unauthenticated portal data disclosure via list request

Published Apr 12, 2024 · Updated Aug 20, 2024

Information disclosure in O2OA 20240403 and earlier allows remote attackers to read portal data through a crafted portal-list request. The /x_portal_assemble_surface/jaxrs/portal/list endpoint returns information for the crafted request, but the responsible function and faulty operation are undisclosed. Exploitation is unauthenticated and high-complexity; published impact is limited to confidentiality, and the exposed fields are not identified.
