GeoVision GeoWebPlayer Websocket Server connectInfo handler stack-based buffer overflow vulnerability_CVE-2026-57275

{
    "lastseen": "",
    "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.\n\nThe 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.\n\n\n\n\n#### Buffer Overflow in username field (key present)",
