CVE-2024-21014Network attack vector

Unauthenticated takeover via undisclosed HTTP flaw

Published Apr 16, 2024 · Updated Mar 17, 2025

Missing authentication in Oracle Hospitality Simphony 19.1.0 through 19.5.4 allows remote attackers to take over the service via HTTP. Oracle identifies the locus only as Simphony Enterprise Server and has not published the affected HTTP endpoint or missing authentication operation. Network access to the HTTP service is sufficient; successful exploitation grants control of the Simphony deployment without credentials.
