CVE-2023-51048
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 · uneditedS-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 confidenceSQL 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm S-CMS installationLook 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
-
Identify S-CMS versionCheck 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
-
Locate vulnerable endpointVerify 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
-
Check for A_newsauth parameter usageSearch 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
-
Verify input sanitization statusInspect 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.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataImplement 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.
