Progress WS_FTP Server < 9.0.6 / 10.0.x < 10.0.3 Multiple Vulnerabilities

critical Nessus Plugin ID 377013

Synopsis

An FTP server installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Progress WS_FTP Server installed on the remote Windows host is prior to 9.0.6 (2024.0.6), or is 10.0.x prior to 10.0.3 (2025.0.3). It is, therefore, affected by multiple vulnerabilities:

- Improper authentication in Progress Software WS_FTP Server versions prior to 2024.0.6 and 2025.0.3 on Windows could allow an unauthenticated remote attacker to access sensitive information, including administrative credentials. (CVE-2026-84295)

- Improper limitation of pathname in the Ad Hoc Transfer component of Progress Software WS_FTP Server versions prior to 2024.0.6 and 2025.0.3 on Windows could allow an authenticated user to access files outside intended directories. (CVE-2026-84294)

- Multi-Factor Authentication Bypass vulnerability in SSH component in Progress Software WS_FTP Server versions prior to 2024.0.6, and 2025.0.3 on Windows allows authenticated users to bypass MFA requirements through improper association of authentication factors between accounts. (CVE-2026-84296)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to WS_FTP Server version 2024.0.6 (9.0.6) / 2025.0.3 (10.0.3) or later.
