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

Executing manipulation of the argument Shippername can lead to sql injection. The attack can be launched remotely. The exploit has been made available to the public and could be exploited.

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 Shippername parameter of /add-courier.php in Courier Management System 1.0 allows remote attackers to execute arbitrary SQL commands via unsanitized input.

MitigationReplace dynamic SQL queries with parameterized statements/prepared statements in add-courier.php and audit other files for similar SQL injection vulnerabilities.

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. Confirm Courier Management System installation
    Locate the web application files on your server. Look for the presence of a directory containing Courier Management System files, particularly add-courier.php.
    Affected if The application is installed and contains add-courier.php from Carmelogarcia Courier Management System version 1.0
  2. Verify the application version
    Check any version file, readme, or metadata within the Courier Management System installation directory. Compare the version to the affected version 1.0.
    Affected if The installed version is exactly 1.0 (Carmelogarcia Courier Management System)
  3. Locate the vulnerable script
    Navigate to the web root of the Courier Management System and confirm that add-courier.php exists.
    Affected if The file add-courier.php is present in the application root
  4. Examine Shippername parameter handling
    Open add-courier.php in a text editor and locate the code handling the 'Shippername' POST or GET parameter. Search for SQL query construction that directly uses this parameter without sanitization or parameterized queries.
    Affected if The Shippername parameter is used in a SQL query without prepared statements, parameter binding, or input sanitization (e.g., direct string concatenation into SELECT/INSERT/UPDATE)
  5. Check other parameters for similar patterns
    Review all form inputs in add-courier.php to see if other parameters are also handled with unsanitized SQL queries.
    Affected if Other parameters in add-courier.php also lack parameterized query handling

Your environment is affected if you have Carmelogarcia Courier Management System version 1.0 installed with add-courier.php present and the Shippername parameter is processed through unsanitized dynamic SQL queries.
