Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

Progress WS_FTP Server versions prior to 2025.0.5 on Windows may store sensitive credentials in a temporary file during transfers. Local access is required to exploit this weakness. The impact is cleartext storage of sensitive information.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Shorten the XFT session timeout where practical, and restrict the Ad Hoc Transfer endpoint to trusted networks if external access is not required. Contact Progress Software Technical Support for guidance on available mitigations.
