CVE-2024-21255Network attack vector

Authenticated takeover via external entity processing

Published Oct 15, 2024 · Updated Mar 13, 2025

XML external entity injection in Oracle PeopleSoft Enterprise PeopleTools 8.59 through 8.61 allows remote authenticated users to take over the system. The CWE-611 mapping indicates that XMLPublisher insufficiently restricts external-entity resolution for untrusted XML, but the parser and request handler are undisclosed. Low-privileged HTTP access is required; successful exploitation grants control of PeopleTools, including its data and service availability.
