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
Grandstream UCM6204 before 1.0.19.20 devices allow remote authenticated users to conduct SQL injection attacks via the sord parameter in a listCodeblueGroup API call to the /cgi? URI.

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 · high confidence

SQL injection vulnerability in the sord parameter of the listCodeblueGroup API endpoint (/cgi?) in Grandstream UCM6204 devices prior to version 1.0.19.20. Authenticated remote attackers can inject malicious SQL queries through this parameter.

MitigationUpgrade UCM6204 firmware to version 1.0.19.20 or later. If immediate patching is not feasible, implement network segmentation and restrict access to the /cgi? API endpoint to trusted, authorized users only.

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. Identify the device model
    Access the device admin interface or check the device label/marketing materials to confirm it is a Grandstream UCM6204 VoIP gateway. The model number is typically visible on the device itself or in the web interface header.
    Affected if The device is a Grandstream UCM6204 model
  2. Check the installed firmware version
    Log into the UCM6204 web administration interface and navigate to the System Status or About page to view the current firmware version. Alternatively, check via CLI if SSH/Telnet access is available.
    Affected if The firmware version is any version prior to 1.0.19.20 (e.g., 1.0.18.x, 1.0.17.x, etc.)
  3. Verify the /cgi API endpoint is accessible
    Confirm network accessibility to the device's web interface on port 8089 or 443, and check if the /cgi endpoint responds to requests. This can be done by attempting a curl or similar request to http://[device-ip]/cgi? or reviewing firewall/network access lists.
    Affected if The /cgi endpoint is reachable from a network where an authenticated attacker could send requests
  4. Confirm authentication is enabled on the API
    Review the UCM6204 user account settings and API access controls to determine if authentication is required for the /cgi endpoint, and verify whether default or weak credentials are in use.
    Affected if An attacker can obtain valid authentication credentials to access the listCodeblueGroup API endpoint

You are affected if you have a Grandstream UCM6204 device running firmware version lower than 1.0.19.20 and the /cgi API endpoint is accessible to an authenticated attacker.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to 1.0.19.20 or later
Fixed in 1.0.19.20
Interim mitigation

Upgrade UCM6204 firmware to version 1.0.19.20 or later. If immediate patching is not feasible, implement network segmentation and restrict access to the /cgi? API endpoint to trusted, authorized users only.
