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
S-CMS v5.0 was discovered to contain a SQL injection vulnerability via the A_newsauth parameter at /admin/ajax.php.

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 S-CMS v5.0 allows remote attackers to inject malicious SQL queries via the A_newsauth parameter at /admin/ajax.php. The lack of proper input sanitization or parameterized queries enables attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or complete system compromise.

MitigationImplement prepared statements/parameterized queries for all database operations involving the A_newsauth parameter and apply strict input validation. If a patched version is available, upgrade immediately.

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 S-CMS installation
    Look for S-CMS files or banners on the web server. Check the website footer, source code, or known S-CMS file paths for the CMS identifier.
    Affected if The system is running S-CMS
  2. Identify S-CMS version
    Check the installed S-CMS version number. Look in admin panels, version files, or meta tags. Compare your version to the affected range (5.0).
    Affected if The installed version is exactly 5.0
  3. Locate vulnerable endpoint
    Verify that the file /admin/ajax.php exists on the web server. Check if this endpoint is accessible via HTTP/HTTPS.
    Affected if The /admin/ajax.php file exists and is accessible
  4. Check for A_newsauth parameter usage
    Search the source code of ajax.php or related files for any usage of the A_newsauth parameter. Look for code that processes this parameter in database queries.
    Affected if The A_newsauth parameter is used in database operations without sanitization
  5. Verify input sanitization status
    Inspect the code handling the A_newsauth parameter. Determine if prepared statements, parameterized queries, or input validation are implemented.
    Affected if No prepared statements or parameterized queries are used for the A_newsauth parameter in database operations

A system is affected if it runs S-CMS version 5.0 and contains the /admin/ajax.php endpoint with vulnerable A_newsauth parameter handling lacking parameterized queries.
