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), a Missing Critical Step in Multi-Factor Authentication of the Web Transfer Module allows users to skip the second-factor verification and log in with username and password only.

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 (2022.0.8) contain a missing critical step in the Multi-Factor Authentication implementation of the Web Transfer Module. This flaw allows authenticated users to bypass the second-factor verification and gain full access using only username and password credentials, effectively circumventing the intended MFA security control.

MitigationUpgrade WS_FTP Server to version 8.8.8 or later to remediate this MFA bypass vulnerability. If immediate upgrade is not feasible, consider disabling the Web Transfer Module and restricting access to FTP client connections only until the upgrade can be applied.

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. Determine WS_FTP Server installed version
    Access the WS_FTP Server administrative console or use the version information command provided in the server documentation. Locate the build or version number displayed in the server status or about section.
    Affected if The installed version is any version prior to 8.8.8 (2022.0.8).
  2. Confirm Web Transfer Module is enabled
    In the WS_FTP Server administrative interface, navigate to the modules or components section and verify whether the Web Transfer Module (also referred to as the web-based transfer interface) is currently active or enabled.
    Affected if The Web Transfer Module is enabled and accessible to users.
  3. Verify MFA configuration for Web Transfer Module
    In the WS_FTP Server admin console, go to the security or authentication settings for the Web Transfer Module and check if Multi-Factor Authentication has been configured or enforced for user logins.
    Affected if MFA is configured or intended to be enforced for the Web Transfer Module, as the vulnerability allows bypassing this second-factor verification.

You are affected if your WS_FTP Server version is below 8.8.8 and the Web Transfer Module is enabled with MFA configured or intended for user authentication.

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 or later to remediate this MFA bypass vulnerability. If immediate upgrade is not feasible, consider disabling the Web Transfer Module and restricting access to FTP client connections only until the upgrade can be applied.

Recommended fix High confidence

Ws FTP Server 8.8.8 (2022.0.8)

  1. 1. Identify the current version of WS_FTP Server by checking the About or version information in the management console
