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

The import-export-for-woocommerce plugin <=1.6.2 has an unrestricted file upload vulnerability allowing attackers to upload dangerous file types including web shells. This enables remote code execution on the server.

MitigationUpdate the plugin to the latest patched version immediately. If no patch is available, disable the plugin and implement web server-level file type restrictions or firewall rules to block executable uploads.

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. Check the plugin version installed
    Navigate to WordPress admin > Plugins > installed plugins > look for 'Import Export for WooCommerce' and note the version number displayed
    Affected if The version shown is 1.6.2 or lower
  2. Verify the vulnerable file upload feature exists
    Check the plugin files for upload handlers - look in the plugin directory for files handling import/export functionality that accept file uploads without validation
    Affected if The plugin has an import/export file upload feature that accepts user-supplied files without proper extension validation
  3. Inspect upload directories for suspicious files
    Search common WordPress upload directories (wp-content/uploads/) for files with executable extensions such as .php, .phtml, .phar, .php5, .php7, or unusual base64-encoded files
    Affected if Any PHP files or other executable scripts are found in upload directories that were not intentionally placed there
  4. Review access logs for file upload requests
    Examine web server access logs for POST requests to the plugin's upload endpoints, particularly those with unusual file extensions or containing suspicious patterns
    Affected if Logs show upload attempts with dangerous file extensions like .php to plugin endpoints
  5. Check for web shell backdoors
    Search the wp-content directory for newly created PHP files with names like shell, cmd, backdoor, or files containing common web shell patterns (base64_decode, system, exec, passthru)
    Affected if Unexpected PHP files are found with code execution functions or obfuscated content

A defender is affected if the installed plugin version is 1.6.2 or lower and the file upload functionality is accessible to users, or if suspicious executable files exist in the upload directories.
