Description
ageLANServer provides a cross-platform web server and launcher for offline multiplayer in several Age of Empires and Age of Mythology games. Prior to version 1.15.2, the AoE3 POST /game/cloud/getFileURL handler in the bundled game server has no request body size limit or cap on the attacker-controlled JSON names array and allocates response storage directly from the unbounded array length. A remote unauthenticated client can use the default self-registration flow and send an oversized request that causes excessive memory allocation, crashes or hangs the server process, disconnects active players, and keeps the service unavailable until it is restarted. This issue is fixed in version 1.15.2.
