Unrestricted Upload of File with Dangerous Type vulnerability in rockgod100 Theme File Duplicator theme-file-duplicator allows Using Malicious Files.This issue affects Theme File Duplicator: from n/a through <= 1.3.

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 Theme File Duplicator plugin for WordPress (versions up to 1.3) contains an unrestricted file upload vulnerability allowing attackers to upload malicious files of dangerous types without proper validation. This can enable remote code execution if executable file types are uploaded and accessed.

MitigationImmediately disable or remove the plugin if no patched version is available. If a patch is released, upgrade promptly. Implement server-side file type validation and restrict upload directories to prevent execution of uploaded files.

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 if the plugin is installed
    Check for the presence of the Theme File Duplicator plugin in your WordPress installation by looking for the directory 'theme-file-duplicator' in wp-content/plugins/ or by viewing the installed plugins list in wp-admin/plugins.php
    Affected if The plugin directory exists in wp-content/plugins/
  2. Identify the installed version
    Access wp-admin/plugins.php and find the Theme File Duplicator plugin entry to view the installed version number, or check the main plugin file header for the 'Version' field
    Affected if The installed version is 1.3 or any version lower than 1.3
  3. Check if the plugin is active
    In wp-admin/plugins.php, verify whether the Theme File Duplicator plugin is currently activated
    Affected if The plugin shows as 'Active' in the plugins list
  4. Audit uploaded files for malicious content
    Inspect the wp-content/uploads/ directory and any custom upload folders configured in the plugin settings for files with dangerous extensions such as .php, .phtml, .php5, .php7, .exe, or .js that were uploaded around the time the plugin was active
    Affected if Any unrecognized or suspicious executable files are found in upload directories, especially .php files that were not intentionally uploaded by an administrator

You are affected if the Theme File Duplicator plugin is installed, is version 1.3 or lower, and is currently active, as this configuration allows unrestricted file uploads that could enable remote code execution.
