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 the Site Editor (aka SiteBuilder) feature 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 Wizard/Edit/Html 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

SQL injection vulnerabilities exist in the Site Editor (SiteBuilder) feature of Parallels Plesk Small Business Panel 10.2.0. Attackers can execute arbitrary SQL commands by injecting malicious input into PHP scripts, specifically including files under Wizard/Edit/Html and related paths. This high-severity (CVSS 7.5) flaw allows remote unauthenticated attackers to potentially compromise the database and underlying system.

MitigationUpgrade to a patched version of Parallels Plesk Small Business Panel; if immediate patching is not feasible, restrict network access to the Site Editor functionality via web server configuration or firewall rules to reduce exposure.

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 Parallels Plesk Small Business Panel installation
    Locate the Plesk installation and identify the installed version. On Linux systems, check /usr/local/psa or use the 'plesk' command-line utility if available. On Windows, check the program installation directory.
    Affected if The product is not installed or cannot be identified as version 10.2.0, this CVE does not apply.
  2. Verify the exact version number
    Run the command to display the Plesk version. On Linux, this may be 'plesk version' or checking /usr/local/psa/version. Compare the installed version to the affected range: version 10.2.0.
    Affected if The installed version is exactly 10.2.0, the environment falls within the affected version range.
  3. Determine if Site Editor (SiteBuilder) feature is enabled
    Access the Plesk administration panel and navigate to the Site Editor or SiteBuilder module settings. Alternatively, check the Plesk database or configuration files for the SiteBuilder feature status.
    Affected if Site Editor/SiteBuilder feature is enabled and accessible to users, the vulnerable component is active.
  4. Inspect for exposed PHP scripts in Wizard/Edit/Html paths
    Check the web server document root for PHP files under paths containing 'Wizard/Edit/Html' or similar SiteBuilder-related directories. These scripts handle user input that could be injected with malicious SQL payload.
    Affected if The vulnerable PHP scripts under Wizard/Edit/Html paths are publicly accessible without additional access controls.

If the environment runs Parallels Plesk Small Business Panel version 10.2.0 with the Site Editor/SiteBuilder feature enabled and the affected PHP scripts are accessible, the environment is vulnerable to CVE-2011-4763.
