CVE-2023-22019Network attack vector

Unauthenticated disclosure of server-accessible data

Published Oct 17, 2023 · Updated Sep 13, 2024

Information disclosure in Oracle HTTP Server 12.2.1.4.0 allows remote attackers to read server-accessible data through HTTP requests. Oracle identifies the affected locus only as the Web Listener and has not disclosed the request-handling error that exposes protected data. No authentication or user interaction is required, and successful exploitation grants read access to critical data or all data accessible to the server.
