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
PHPJabbers Simple CMS 5.0 contains a SQL injection vulnerability in the 'column' parameter that allows remote attackers to manipulate database queries. Attackers can inject crafted SQL payloads through the 'column' parameter in the index.php endpoint to potentially extract or modify database information.

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

PHPJabbers Simple CMS 5.0 contains a SQL injection vulnerability in the 'column' parameter of index.php. Attackers can inject malicious SQL payloads to manipulate database queries, potentially allowing extraction or modification of sensitive data.

MitigationImplement proper input validation and use parameterized queries/prepared statements to sanitize the 'column' parameter before executing database queries. Apply vendor patches if available.

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 PHPJabbers Simple CMS version
    Check the application version by examining the source code, typically found in a version file, about page, or meta tags within the web application files
    Affected if The installed version is exactly 5.0 (version 5.0 is the only affected version)
  2. Locate index.php entry point
    Find the main index.php file in the web application root directory and verify it processes the 'column' parameter in database queries
    Affected if The index.php file exists and processes the 'column' parameter without proper sanitization
  3. Verify parameter handling in code
    Examine the index.php file to confirm the 'column' parameter is used directly in SQL queries without prepared statements or input validation
    Affected if The 'column' parameter is concatenated directly into SQL queries without parameterization
  4. Check application accessibility
    Determine if the vulnerable endpoint is accessible over the network (HTTP/HTTPS) by attempting to access the index.php page
    Affected if The application is accessible remotely and the index.php endpoint responds to requests

You are affected if PHPJabbers Simple CMS version 5.0 is installed and the index.php file processes the 'column' parameter in SQL queries without prepared statements.
