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
A vulnerability has been found in itsourcecode Courier Management System 1.0. Impacted is an unknown function of the file /manage_user.php. Such manipulation of the argument ID leads to sql injection. The attack may be performed from remote. The exploit has been disclosed to the public and may be used.

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 · moderate confidence

SQL injection vulnerability in itsourcecode Courier Management System 1.0 at /manage_user.php via the ID parameter. The application fails to properly sanitize user input before using it in SQL queries, allowing remote attackers to inject malicious SQL syntax and potentially extract, modify, or delete database contents.

MitigationReplace dynamic SQL queries with parameterized queries/prepared statements in manage_user.php, implement strict input validation on the ID parameter, and apply principle of least privilege to the database user account.

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 the Courier Management System installation
    Search the web server document root for manage_user.php file. Common paths include /var/www/html/, /www/, or C:\inetpub\wwwroot\. Run: find /var/www -name 'manage_user.php' 2>/dev/null
    Affected if The manage_user.php file is found in the system, indicating the vulnerable component is present
  2. Verify the application version
    Check for version indicators such as a version.php file, footer in the application, or a readme.txt in the root directory. Look for '1.0' as the installed version.
    Affected if The installed version is Courier Management System 1.0, matching the affected version range
  3. Examine the ID parameter handling in manage_user.php
    Open manage_user.php in a text editor and locate code that handles the 'ID' or 'id' parameter from GET/POST requests. Search for patterns like $_GET['id'], $_POST['id'], or $id without prepared statements.
    Affected if The code uses direct variable insertion into SQL queries (e.g., "SELECT * FROM users WHERE id='" . $id . "'") without using prepared statements or parameter binding
  4. Confirm SQL query construction method
    Look for SQL query construction patterns in manage_user.php. Check if database queries concatenate user input directly, for example: mysql_query("SELECT... WHERE id=$id") or similar patterns without mysqli_prepare() or PDO::prepare().
    Affected if The SQL queries are constructed using string concatenation with user input rather than parameterized queries (prepared statements)
  5. Test the parameter with diagnostic input
    If the application is accessible, send a benign SQL injection test string to the ID parameter in manage_user.php, such as ID=1' (observe but do not exploit). Check if the application returns a database error.
    Affected if Submitting a single quote to the ID parameter causes a database SQL error, confirming the parameter is not sanitized and vulnerable to injection

If manage_user.php exists on the system, the application is version 1.0, and the ID parameter uses direct string concatenation in SQL queries without prepared statements, the environment is vulnerable to CVE-2026-9606.

Mitigation

Replace dynamic SQL queries with parameterized queries/prepared statements in manage_user.php, implement strict input validation on the ID parameter, and apply principle of least privilege to the database user account.
