## Technical details

A stack-based buffer overflow exists in the 'handle_connection_info' function of the GeoWebPlayer WebSocket server. The vulnerability is caused by a manual byte-by-byte loop that copies the 'password' field from an attacker-controlled JSON object into a fixed-size 64-byte buffer without performing length validation. While the WebSocket server listens on localhost, an attacker can exploit this remotely by staging a malicious webpage that sends a specially crafted WebSocket message to the local service. Successful exploitation can lead to arbitrary code execution in the context of the plugin. This issue is specific to the code path where no 'key' variable is provided in the JSON payload.
