CVE-2025-56435
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 · uneditedSQL Injection vulnerability in FoxCMS v1.2.6 and before allows a remote attacker to execute arbitrary code via the. file /DataBackup.php and the operation on the parameter id.
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 confidenceA SQL injection vulnerability exists in FoxCMS v1.2.6 and earlier in the /DataBackup.php file through the 'id' parameter, allowing remote attackers to inject malicious SQL queries.

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.
-
Identify FoxCMS installation and versionLocate the FoxCMS installation directory on your server. Check for version indicators such as a version.php file, a config file, or the CMS admin panel which often displays the version. Compare your found version against the affected range: <= 1.2.6Affected if FoxCMS version 1.2.6 or earlier is installed
-
Locate the DataBackup.php fileSearch for the DataBackup.php file within your FoxCMS installation directory, typically in the root or admin directory. This file is part of the CMS core and should exist in affected versions.Affected if The DataBackup.php file exists in your FoxCMS installation
-
Verify the 'id' parameter is processed by DataBackup.phpExamine the DataBackup.php source code and look for $_GET or $_POST references to the 'id' parameter. Check if this parameter is used in any SQL query construction without proper escaping or parameterized queries.Affected if The DataBackup.php file processes an 'id' parameter from user input and uses it in SQL queries without prepared statements
-
Check if the backup feature is accessibleDetermine if the DataBackup.php file is accessible via web requests (e.g., attempting to access yourdomain.com/DataBackup.php or checking web server configuration). The vulnerability is exploitable remotely if the file is web-accessible.Affected if The DataBackup.php file is web-accessible and accepts user-supplied input for the 'id' parameter
You are affected if FoxCMS version 1.2.6 or earlier is installed, the DataBackup.php file exists, and it processes the 'id' parameter in SQL queries without proper input sanitization.

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 dataReplace dynamic SQL queries with parameterized queries/prepared statements in DataBackup.php, implement strict input validation on the 'id' parameter, or upgrade to a patched version of FoxCMS if available.
