CVE-2026-57276 Details
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 password field (key present)
A stack-based buffer overflow vulnerability has been identified in the GeoWebPlayer Websocket Server, specifically in the 'connectionInfo' command handler. This vulnerability exists in GeoWebPlayer version 1.1.1.0. The issue arises because the 'handle_connection_info' function copies attacker-controlled JSON strings into fixed-size buffers without proper length validation, allowing for arbitrary code execution. The vulnerability can be exploited by sending a crafted websocket message that exceeds the buffer size.
GeoVision has released a patch for this vulnerability. Users can download the latest version of GeoWebPlayer from the GeoVision product download page, provided the product is still supported.
