CVE-2023-38419Network attack vector

Authenticated service interruption via undisclosed SOAP requests

Published Aug 2, 2023 · Updated Oct 11, 2024

Denial of service in F5 BIG-IP and BIG-IQ iControl SOAP allows remote authenticated users to terminate the SOAP process. F5 has not disclosed the request form or exact handling error; it states only that undisclosed requests make the iControl SOAP process terminate. Guest-level credentials or higher and network access to iControl SOAP are required, and the bounded consequence is interruption of that service.
