CVE-2024-21082Network attack vector

Unauthenticated takeover via XML external entity processing

Published Apr 16, 2024 · Updated Mar 26, 2025

XML external entity injection in Oracle BI Publisher 7.0.0.0.0 and 12.2.1.4.0 allows remote attackers to take over the service via HTTP. The XML Services component processes attacker-supplied XML without adequately restricting external entity references; Oracle has not disclosed the affected endpoint or parser path. No authentication or user interaction is required, and successful exploitation grants complete control of BI Publisher data and service operation.
