Low risk12th percentile — higher than 12% of all known CVEs
Summary
A vulnerability in GeoWebPlayer (Web Plugin/WS Player) for GeoVision software (GV-VMS, GV-Cloud) stems from missing validation of the `index` value in commands received from localhost. This allows out-of-bounds array access, potentially leading to uncontrolled behavior.
Risk Assessment
An attacker on the local host could exploit this flaw to perform unauthorized operations, potentially destabilizing the system or accessing sensitive data.
Recommendation
Update GeoWebPlayer to the latest version provided by the vendor and restrict access to the websocket server to trusted processes only.
Original NVD description (English source)
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. #### play command index-out-of-bound
