ffxivlauncher.exe in Square Enix Final Fantasy XIV 4.21 and 4.25 on Windows is affected by Improper Enforcement of Message Integrity During Transmission in a Communication Channel, allowing a man-in-the-middle attacker to steal user credentials because a session retrieves global.js via http before proceeding to use https. This is fixed in Patch 4.3.
The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission.
