GeoWebPlayer WebSocket Index Out-of-Bounds Access

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 that include an 'index' value used to access arrays for critical operations. However, the 'index' is not properly validated for valid range, allowing out-of-bound access to multiple arrays.

Impact Analysis

Because the 'index' value is not checked for valid range, an attacker can exploit this to access arrays out-of-bound, potentially leading to unauthorized access to critical sections, execution of unintended function calls, and other harmful actions. This can result in a 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 value that is not properly range-checked, leading to out-of-bounds array access. Detection would involve monitoring websocket traffic on the affected system, especially commands sent to the GeoWebPlayer websocket server that include index parameters.

Since the vulnerable commands are accepted only from localhost, network detection might be limited to local monitoring or host-based detection.

Suggested detection steps include:

• Monitor websocket server logs or traffic on localhost for suspicious commands containing out-of-range index values.
• Use system tools to check for unexpected websocket server behavior or crashes related to GeoWebPlayer.
• No specific commands are provided in the available information to detect this vulnerability directly.

Mitigation Strategies

Immediate mitigation steps should focus on applying available patches or updates from GeoVision, as they maintain a structured vulnerability management process and release unscheduled updates for critical vulnerabilities.

Since the vulnerability involves out-of-bounds access via the GeoWebPlayer websocket server, restricting access to the websocket server to trusted processes or disabling the GeoWebPlayer addon if not required can reduce risk.

GeoVision's cybersecurity policy emphasizes prompt updates and detailed documentation for critical vulnerabilities, so checking their official site for patches or advisories related to this CVE is recommended.
