CVE-2025-4375Network attack vector

Session hijacking via unvalidated cross-site requests

Published May 9, 2025 · Updated May 9, 2025

CSRF in Sparx Systems Pro Cloud Server 6.0.14 and earlier allows remote attackers to hijack an administrator session through WebEA. WebEA accepts state-changing requests without verifying that they originated from the legitimate application, enabling a forged request to change the Pro Cloud Server Configuration password. A privileged user must have an active session and passively load attacker-controlled content; a successful request can reset the configuration password.
