Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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. #### setStream command index-out-of-bound

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

GeoWebPlayer's websocket server does not validate the `index` parameter in commands before using it to access arrays. This allows out-of-bounds array access when an attacker supplies an invalid index value, potentially leading to memory corruption or information disclosure. The vulnerability exists in the command handling logic for localhost connections.

MitigationApply vendor patch when available. Until then, restrict access to the localhost websocket interface, disable GeoWebPlayer if not required, and monitor for unusual command patterns. Network segmentation may limit exposure from local attack vectors.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm GeoWebPlayer is installed
    Look for GeoWebPlayer in installed programs (Windows: Add/Remove Programs, Linux: check common installation directories like /opt/, /usr/local/, or package managers)
    Affected if GeoWebPlayer is present on the system
  2. Identify GeoWebPlayer version
    Check the application's about page, installation directory for version files, or run: geowebplayer --version (if CLI exists)
    Affected if Version cannot be determined or is within an unpatched release range
  3. Verify websocket server is enabled
    Check GeoWebPlayer configuration files for websocket/server settings, or look for process listening on common websocket ports (check netstat -an for ports 8080, 9090, or application-specific ports)
    Affected if Websocket server is running and accepting connections
  4. Check localhost binding configuration
    Inspect configuration files (often XML, JSON, or .ini files in config/ or settings/ directories) for bind address or listen interface settings
    Affected if Service binds to 127.0.0.1 or 0.0.0.0 allowing localhost access
  5. Test websocket command interface
    Connect to the websocket endpoint (e.g., ws://127.0.0.1:<port>/) and send a command with an out-of-range index parameter to observe behavior
    Affected if Commands accept index parameters and respond without bounds validation

User is affected if GeoWebPlayer is installed with websocket server enabled and accessible from localhost, and the installed version lacks the index parameter validation fix.
