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 version 2.x contains an SQL injection vulnerability in the 'index.php' authentication mechanism that allows attackers to manipulate login credentials. Attackers can inject malicious SQL code through the 'password' POST parameter to bypass authentication and potentially gain unauthorized access to the system.

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

SOUND4 IMPACT/FIRST/PULSE/Eco version 2.x contains a critical SQL injection vulnerability in the 'index.php' authentication mechanism. Attackers can inject malicious SQL code through the 'password' POST parameter to manipulate login credentials and bypass authentication entirely, potentially gaining full unauthorized access to the system.

MitigationUpgrade to a patched version if available; otherwise, implement strict input validation and use parameterized queries (prepared statements) for all database interactions in the authentication logic to neutralize SQL injection 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. Identify Sound4 product installation
    Check for the presence of Sound4 web interface by accessing the target system on common HTTP ports (80, 443, 8080) and looking for the index.php login page. Also check for Sound4-specific HTTP headers or server banners in responses.
    Affected if The system is running a SOUND4 IMPACT, FIRST, PULSE, or Eco web interface on the network.
  2. Determine firmware version
    Access the system's admin or status page, typically found at /admin, /status, or within the web interface footer/header. Alternatively, check HTTP server headers or the firmware version display in the login page source.
    Affected if The installed firmware version matches: 2.15, 1.69, 1.16, 1.2, 1.30, or 1.11 for the affected product lines.
  3. Verify vulnerable login endpoint exists
    Confirm that index.php accepts POST requests with a 'password' parameter by examining the login form HTML source or by attempting a login request. The vulnerable code directly incorporates the password parameter into SQL queries.
    Affected if The index.php login page accepts a POST 'password' parameter without visible input sanitization or parameterized query implementation.
  4. Check authentication mechanism
    Review the authentication flow in index.php if access to source code is available, or test with SQL injection payloads in the password field to confirm the vulnerability exists. A successful SQL injection will bypass authentication.
    Affected if The password parameter is not sanitized or parameterized, allowing SQL injection payloads to manipulate the authentication query.

You are affected if you are running any of the listed Sound4 firmware versions (2.15, 1.69, 1.16, 1.2, 1.30, or 1.11) on IMPACT, FIRST, PULSE, Eco, Big Voice4, Big Voice2, or Wm2 products and the web login interface is accessible.

Mitigation

Upgrade to a patched version if available; otherwise, implement strict input validation and use parameterized queries (prepared statements) for all database interactions in the authentication logic to neutralize SQL injection vectors.
