GeoWebPlayer (also called "Web Plugin" in the GV-VMS documentation and "WS Player" for VMS-Cloud) is an addon that can be installed with various GeoVision software (GV-VMS, GV-Cloud, ...). It creates a websocket server that expands the capabilities of the various web-interfaces provided by the GeoVision software and may be necessary for them to function properly.

The Websocket server can accept various commands coming from localhost. One of them, connectionInfo is meant to provide the necessary details to connect to a camera. The handler associated with this command that we callhandle_connection_info contains multiple instances of string copy that can overflow. The function handle_connect_info copies attacker-controlled JSON strings into fixed-size buffers using manual byte-by-byte loops that do not enforce length limits.
