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
Multiple SQL injection vulnerabilities in Parallels Plesk Small Business Panel 10.2.0 allow remote attackers to execute arbitrary SQL commands via crafted input to a PHP script, as demonstrated by domains/sitebuilder_edit.php and certain other files.

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

Multiple SQL injection vulnerabilities in Parallels Plesk Small Business Panel 10.2.0 allow remote unauthenticated attackers to execute arbitrary SQL commands via crafted input to PHP scripts, specifically demonstrated in domains/sitebuilder_edit.php and other files.

MitigationRemediate by implementing parameterized queries or prepared statements in all affected PHP files, conducting a full code audit to identify additional vulnerable endpoints, and applying input validation and sanitization across the application.

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. Verify Parallels Plesk Small Business Panel is installed
    Check for the presence of Plesk Small Business Panel installation directories, typically under /usr/local/psa or /opt/psa, or look for the Plesk control panel service running on ports 8443 or 8880
    Affected if The product is not installed or this is a different product
  2. Confirm the exact version is 10.2.0
    Check the Plesk version via the admin interface, command line (plesk --version or mmm --version), or by inspecting version files in the installation directory
    Affected if The installed version is not exactly 10.2.0 (the vulnerability only affects this specific version)
  3. Locate the vulnerable PHP script domains/sitebuilder_edit.php
    Search for the file sitebuilder_edit.php within the Plesk web directories, typically under the /domains/ or /admin/ subdirectories of the Plesk document root
    Affected if The file does not exist (may have been removed or this is a different installation variant)
  4. Verify the PHP scripts are accessible via HTTP/HTTPS
    Attempt to access the identified vulnerable PHP scripts (such as domains/sitebuilder_edit.php) through the web server to confirm they respond to requests
    Affected if The PHP scripts are not accessible or not exposed via the web server (no attack surface)

The environment is affected only if Parallels Plesk Small Business Panel version 10.2.0 is installed with the vulnerable PHP scripts (specifically domains/sitebuilder_edit.php and similar files) accessible via the web server.
