CVE-2023-40148Network attack vector

Unauthenticated network access via forged POST requests

Published Apr 10, 2024 · Updated Aug 12, 2024

Server-side request forgery in Ping Identity PingFederate allows remote attackers to reach network resources via forged HTTP POST requests. An unauthenticated POST handler causes the server to issue attacker-directed HTTP requests without adequate destination restriction; the affected endpoint and function are undisclosed. No credentials or user interaction are required, and the requests can access internal network resources or consume server-side resources.
