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
Guardian language-system passes the id GET parameter directly into a PHP exec() call in transcribe_amazon.php (line 15) without sanitization: exec(\"php jobs/transcribe_amazon.php \".$login_session.\" \".$_GET['id'].\" ...\"). No authentication is required. An unauthenticated remote attacker can append shell metacharacters to execute arbitrary OS commands on the server.

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

Guardian language-system has an OS command injection vulnerability in transcribe_amazon.php where the 'id' GET parameter is passed directly to a PHP exec() call without sanitization, allowing unauthenticated attackers to execute arbitrary OS commands by injecting shell metacharacters.

MitigationImplement strict input validation and sanitization for all user-supplied parameters before use in system calls, or refactor the code to avoid passing user input to exec() entirely. The vulnerable script should be disabled immediately until patched.

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. Locate transcribe_amazon.php in the environment
    Search the web root and application directories for the file transcribe_amazon.php using commands such as: find /var/www -name 'transcribe_amazon.php' or dir /s /b transcribe_amazon.php on Windows
    Affected if The file exists in the environment
  2. Confirm the script is web-accessible
    Attempt to access transcribe_amazon.php via HTTP/HTTPS request to verify it is exposed through the web interface without requiring authentication
    Affected if The script is directly accessible over the network without authentication
  3. Inspect the 'id' parameter handling
    Open transcribe_amazon.php and examine how the 'id' GET parameter is processed - look for the exec() function call and trace whether the 'id' parameter value is used directly within it without sanitization, escaping, or validation
    Affected if The 'id' parameter is passed to exec() without any sanitization or shell escaping
  4. Identify the Guardian language-system version
    Check for version information in version files, configuration files, or within the application itself to determine which version of the software is installed
    Affected if The installed version matches any known affected version range for this vulnerability
  5. Verify unauthenticated command execution is possible
    Send a crafted request to transcribe_amazon.php with shell metacharacters in the 'id' parameter (for example: ?id=test;whoami) to confirm arbitrary command injection is possible without authentication
    Affected if The injected commands execute and return results, confirming the vulnerability is present and exploitable

The environment is affected if transcribe_amazon.php exists, is web-accessible without authentication, and passes the 'id' GET parameter directly to exec() without sanitization.
