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.php (line 15) without sanitization: exec(\"php jobs/transcribe.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

Command injection vulnerability in Guardian language-system's transcribe.php where the 'id' GET parameter is passed unsanitized to a PHP exec() call. An unauthenticated remote attacker can inject shell metacharacters to execute arbitrary OS commands with the privileges of the web server.

MitigationImmediately restrict access to transcribe.php or disable the vulnerable functionality until a patch can be applied. Implement proper input validation/sanitization to prevent shell metacharacter injection, ideally by avoiding exec() calls with user input entirely.

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.php in the web application
    Search the web root and application directories for a file named transcribe.php using file system search commands (e.g., find, ls, or directory listing tools).
    Affected if The file transcribe.php exists in the application directory tree.
  2. Verify exec() usage in transcribe.php
    Open transcribe.php and search for instances of the exec() function or similar shell execution functions (system, shell_exec, passthru).
    Affected if The file contains exec() or related shell execution functions.
  3. Inspect 'id' parameter handling
    Examine how the 'id' GET parameter is retrieved (e.g., $_GET['id']) and trace its usage through the code to see if it flows into exec() calls.
    Affected if The 'id' GET parameter is passed directly to exec() without sanitization.
  4. Confirm absence of input sanitization
    Check whether the 'id' parameter is processed through sanitization functions such as escapeshellarg(), escapeshellcmd(), or other input validation before reaching exec().
    Affected if The 'id' parameter is NOT sanitized with escapeshellarg() or equivalent before being used in exec().

The environment is affected if transcribe.php exists and uses the 'id' GET parameter in an exec() call without proper input sanitization using escapeshellarg() or equivalent.

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.
