Summary
GeoWebPlayer (also known as Web Plugin or WS Player) is an addon for GeoVision software (GV-VMS, GV-Cloud) that creates a WebSocket server. Many commands accept an `index` parameter that is not validated for range, allowing out-of-bounds array access.
Risk Assessment
An attacker on localhost can exploit this vulnerability to read or write out-of-bounds memory, potentially leading to data corruption, service disruption, or arbitrary code execution.
Recommendation
Immediately update GeoWebPlayer to the latest version provided by the vendor and restrict WebSocket server access to trusted local processes only.
Original NVD description (English source)
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. Many of the commands will take an `index` value that is then used to access various arrays to enter critical sections, perform various actions via function calls, etc. However the `index` value is usually not checked for valid range, and as such it can be used to access multiple arrays out-of-bound. #### audio command index-out-of-bound
