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
The Control Panel in Parallels Plesk Panel 10.2.0 build 20110407.20 includes a database connection string within a web page, which allows remote attackers to obtain potentially sensitive information by reading this page, as demonstrated by client@2/domain@1/hosting/aspdotnet/.

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

The Parallels Plesk Panel 10.2.0 Control Panel exposes database connection strings within a web page (specifically the /hosting/aspdotnet/ endpoint), allowing remote unauthenticated attackers to obtain potentially sensitive database credentials via direct web access.

MitigationRestrict access to the affected Control Panel pages and ensure database connection strings are not rendered in HTML output; apply vendor patches and audit similar endpoints for credential 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 Plesk Panel version
    Access the Plesk Panel administrative interface and navigate to Server > License Management or Help > About to view the installed version and build number
    Affected if Version is 10.2.0 with build20110407.20
  2. Test /hosting/aspdotnet/ endpoint accessibility
    Send an HTTP GET request to the URL pattern: http://<plesk_server_hostname>/hosting/aspdotnet/ - no authentication should be required to access this endpoint
    Affected if The endpoint returns an HTTP 200 OK status rather than redirecting to a login page, returning 403, or 404
  3. Inspect response for credential exposure
    Examine the full HTTP response body from the /hosting/aspdotnet/ endpoint. Search for plaintext patterns including 'Data Source', 'Server=', 'Database=', 'User ID=', 'Password=', connection strings using semicolon-separated key=value pairs, or any visible database server hostnames and usernames
    Affected if The HTML response contains any database connection strings, connection parameters with values, or credentials in plaintext

The environment is affected if running Plesk Panel version 10.2.0 build20110407.20 AND the /hosting/aspdotnet/ endpoint is accessible without authentication AND returns database connection strings in the response body.

Mitigation

Restrict access to the affected Control Panel pages and ensure database connection strings are not rendered in HTML output; apply vendor patches and audit similar endpoints for credential exposure.
