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
In WS_FTP Server versions before 8.8.8 (2022.0.8), an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Web Transfer Module allows File Discovery, Probe System Files, User-Controlled Filename, Path Traversal.   An authenticated file download flaw has been identified where a user can craft an API call that allows them to download a file from an arbitrary folder on the drive where that user host's root folder is located (by default this is C:)

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

WS_FTP Server versions before 8.8.8 contain a path traversal vulnerability in the Web Transfer Module. An authenticated attacker can craft malicious API calls to download files from arbitrary locations on the server's filesystem by manipulating file paths, potentially accessing system files outside the intended upload/download directory.

MitigationUpgrade WS_FTP Server to version 8.8.8 (2022.0.8) or later. Implement strict input validation on file path parameters to prevent directory traversal sequences (../) and restrict file operations to authorized directories.

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 installed WS_FTP Server version
    Check the installed version through the WS_FTP Server administration console, or use the product's built-in version check command or About dialog. Compare against the affected version range of < 8.8.8.
    Affected if The installed version is any release before 8.8.8 (including 8.8.7, 8.8.6, earlier 8.x releases, or older major versions).
  2. Confirm Web Transfer Module is enabled
    Access the WS_FTP Server administration interface and verify the Web Transfer Module service is running and accessible. This module provides the HTTP/HTTPS-based file transfer API.
    Affected if The Web Transfer Module service is active and accepting connections.
  3. Verify API authentication is configured
    Check if user authentication is enabled for the Web Transfer Module API endpoints. Determine which user accounts have API access privileges.
    Affected if Authenticated users or service accounts can make API calls to the Web Transfer Module.
  4. Check file operation permissions
    Review the Web Transfer Module configuration to identify which directories are accessible for upload and download operations, and which users have access to those operations.
    Affected if Authenticated users have permission to perform file download operations through the API.

Your environment is affected if WS_FTP Server version is below 8.8.8 AND the Web Transfer Module is enabled with authenticated API access to file download operations.

Upgrade available Upgrade to 8.8.8 or later
Fixed in 8.8.8
Interim mitigation

Upgrade WS_FTP Server to version 8.8.8 (2022.0.8) or later. Implement strict input validation on file path parameters to prevent directory traversal sequences (../) and restrict file operations to authorized directories.

Recommended fix High confidence

8.8.8 (2022.0.8)

  1. Identify the current installed version of WS_FTP Server by checking the application or using the server's version information
  2. Download WS_FTP Server version 8.8.8 (2022.0.8) or later from the official Progress website (www.progress.com) or authorized distribution channels
  3. Review the upgrade documentation and release notes for version 8.8.8
  4. Ensure you have a complete backup of the WS_FTP Server configuration and data
  5. Schedule a maintenance window for the upgrade process
  6. Stop the WS_FTP Server services before beginning the upgrade
  7. Install version 8.8.8 following the standard upgrade procedure
  8. Verify the installation completed successfully
Caveat No specific breaking changes documented in the provided description; standard upgrade best practices and pre-upgrade backups are recommended
