Description
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 call`handle_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. #### Buffer Overflow in username field (key present)
