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.

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-bounds array access.

Detection on your network or system would involve monitoring websocket traffic to the GeoWebPlayer server, especially commands that include an index parameter.

Since the websocket server listens locally, detection could include checking for unusual or malformed websocket messages sent to the GeoWebPlayer process on localhost.

However, no specific detection commands or signatures are provided in the available information.

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.

Compliance Impact

The provided information does not explicitly describe how CVE-2026-57264 affects compliance with common standards and regulations such as GDPR or HIPAA.

Mitigation Strategies

Immediate mitigation steps should include applying any available patches or updates provided by GeoVision for the GeoWebPlayer component.

GeoVision follows a structured vulnerability management process and releases unscheduled updates for critical vulnerabilities such as this one.

If a patch is not yet available, restricting access to the GeoWebPlayer websocket server, especially limiting localhost access or disabling the addon if not required, can reduce risk.

Monitoring and blocking suspicious websocket commands with out-of-bound index values may also help mitigate exploitation attempts.
