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. 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. #### setPIP command index-out-of-bound

Executive Summary

The vulnerability exists in GeoWebPlayer, an addon for GeoVision software, which creates a websocket server to enhance web-interface capabilities. This server accepts commands from localhost, many of which use an 'index' value to access arrays for critical operations. However, the 'index' value is not properly validated for its range, allowing out-of-bound access to multiple arrays.

Specifically, the 'setPIP' command suffers from this index-out-of-bound issue, which can lead to unexpected behavior or exploitation.

Impact Analysis

Because the vulnerability allows out-of-bound array access via the websocket server commands, it can lead to critical security impacts including unauthorized code execution or manipulation of the system.

The CVSS score of 8.3 indicates a high severity, with potential impacts on confidentiality, integrity, and availability of the affected system.
