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
SOUND4 IMPACT/FIRST/PULSE/Eco <=2.x contains an SQL injection vulnerability in the 'username' POST parameter of index.php that allows attackers to manipulate database queries. Attackers can inject arbitrary SQL code through the username parameter to bypass authentication and potentially access unauthorized database information.

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 authentication login form (index.php) of SOUND4 audio processing devices. The 'username' POST parameter is not properly sanitized before being used in SQL queries, allowing attackers to inject arbitrary SQL code to bypass authentication or exfiltrate database contents.

MitigationReplace dynamic SQL query construction with parameterized queries (prepared statements) in the authentication code. Implement strict input validation as an additional layer of defense.

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 Sound4 device model
    Access the device web interface or check device documentation/labels to confirm it is a Sound4 audio processing device (Impact, Pulse, First, Impact Eco, Pulse Eco, Big Voice4, Big Voice2, or Wm2)
    Affected if The device is any of these Sound4 models
  2. Check firmware version
    Log into the device web interface or access the admin/system information page to view the installed firmware version
    Affected if The firmware version is 2.15, 1.69, 1.16, 1.2, 1.30, or 1.11 for the respective model listed in the affected products
  3. Verify web interface is accessible
    Attempt to access the device login page at index.php over the network (http/https)
    Affected if The web interface login form is reachable over the network
  4. Confirm username POST parameter exists
    Inspect the login form HTML source or capture a POST request to index.php during login to verify the 'username' parameter is present
    Affected if The login form submits a 'username' parameter via POST to index.php
  5. Check if remote authentication is enabled
    Determine whether the device allows remote network access to the web authentication interface (check network settings or firewall rules)
    Affected if Remote access to the web login form is permitted on the network

The environment is affected if it is a Sound4 device (Impact, Pulse, First, Impact Eco, Pulse Eco, Big Voice4, Big Voice2, or Wm2) running the specific vulnerable firmware versions (2.15, 1.69, 1.16, 1.2, 1.30, or 1.11) and the web interface with the login form is accessible.
