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 suexec implementation in Parallels Plesk Panel 11.0.9 contains a cgi-wrapper whitelist entry, which allows user-assisted remote attackers to execute arbitrary PHP code via a request containing crafted environment variables.

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.

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. Identify Plesk Panel version
    Run the Plesk version check command or inspect the Plesk admin interface to determine the exact installed version of Parallels Plesk Panel
    Affected if The installed version is exactly 11.0.9
  2. Confirm cgi-wrapper is configured

    Affected if cgi-wrapper is enabled and the Plesk version is 11.0.9
  3. Inspect cgi-wrapper whitelist configuration
    Locate and examine the cgi-wrapper whitelist configuration file in the Plesk Panel installation directory to review allowed executables
    Affected if The whitelist contains entries that could be bypassed through environment variable manipulation and the version is 11.0.9

The environment is affected only if the installed Parallels Plesk Panel version is exactly 11.0.9 and the cgi-wrapper feature is enabled with a configurable whitelist.
