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

Executive Summary

This vulnerability exists in GeoWebPlayer, an addon for GeoVision software that creates a websocket server to enhance web-interface capabilities. The server accepts commands from localhost that include an 'index' value used to access arrays for various actions. However, the 'index' is not properly checked for valid range, allowing out-of-bound access to multiple arrays.

Impact Analysis

Because the vulnerability allows out-of-bound array access via the 'index' parameter, it can lead to critical issues such as unauthorized access to memory, execution of unintended functions, or manipulation of critical sections. This can result in high impact on confidentiality, integrity, and availability of the affected system.

Detection Guidance

This vulnerability involves the GeoWebPlayer websocket server accepting commands from localhost with an index value that is not properly checked for valid range, leading to out-of-bound array access.

Detection could involve monitoring or testing the websocket server for commands that include out-of-bound index values.

However, no specific detection commands or network scanning techniques are provided in the available information.

Mitigation Strategies

The vulnerability arises from improper validation of index values in commands sent to the GeoWebPlayer websocket server.

Immediate mitigation steps would typically include restricting access to the websocket server to trusted localhost processes only and applying any available patches or updates from the vendor.

No specific mitigation instructions or workarounds are provided in the available information.
