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
Path Traversal in create template function in EasyUse MailHunter Ultimate 2023 and earlier allow remote authenticated users to extract files into arbitrary directories via a crafted ZIP archive.

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

A path traversal vulnerability in the create template function of EasyUse MailHunter Ultimate 2023 and earlier allows authenticated remote users to upload crafted ZIP archives containing files with path traversal sequences (e.g., ../../filename), enabling arbitrary file extraction to directories outside the intended template directory.

MitigationImplement strict validation of file paths within ZIP archives before extraction, including checking for and rejecting path traversal sequences (..), ensuring extracted files remain within the designated template directory, and using secure path resolution methods.

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 EasyUse MailHunter Ultimate installation
    Locate the EasyUse MailHunter Ultimate application on the system or identify it via installed programs list. Note the exact version number displayed.
    Affected if The application is installed and version displays as 2023 or earlier (e.g., 2022, 2021, etc.)
  2. Identify template creation feature access
    Determine whether authenticated user accounts exist that have access to the template creation or import functionality within the application.
    Affected if Authenticated users can access the template creation/import feature
  3. Verify ZIP archive upload capability
    Check if the template import feature accepts ZIP file uploads - this is the attack vector for the path traversal vulnerability.
    Affected if The template creation function accepts ZIP archive uploads from users
  4. Review for path traversal protection
    Inspect application logs or template extraction behavior to determine if path traversal sequences (..) within ZIP archives are validated or blocked before extraction.
    Affected if No validation of path traversal sequences is performed on ZIP contents before extraction, allowing files to be placed outside the intended template directory
  5. Check authentication requirements
    Verify whether the template upload feature requires authentication, as the CVE requires authenticated remote users.
    Affected if The template creation/upload feature is accessible to authenticated users without additional security controls on path traversal

The environment is affected if EasyUse MailHunter Ultimate version 2023 or earlier is installed, the template creation feature accepts ZIP uploads, and path traversal sequences within ZIP archives are not validated before extraction.
