WebSocket Server Index Out-of-Bounds in GeoWebPlayer

Mitigation Strategies

The available information does not provide explicit mitigation steps.

General best practices would include restricting access to the GeoWebPlayer websocket server to trusted localhost processes only, applying any available patches or updates from the vendor, and monitoring for suspicious activity involving commands with index parameters.

Executive Summary

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

Impact Analysis

Because the 'index' value is not validated, an attacker can exploit this to perform out-of-bound array accesses. This can lead to entering critical sections improperly and executing unintended function calls, potentially resulting in high impact on confidentiality, integrity, and availability of the system.

Detection Guidance

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

Detection would 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.
