Password Disclosure via Activity Logs Enabling Administrator Privilege Escalation in WS_FTP Server

Impact

Progress Software WS_FTP Server versions prior to 2024.0.7 and 2025.0.4 on Windows may expose a user's password to another administrator, potentially allowing privilege escalation. An attacker would need access to activity logs. The vulnerability is due to insufficient protection of credentials and sensitive information in log files.

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

What to do

Restrict access to administrative logs to trusted personnel. Avoid changing privileged account passwords through FTP until the fix is applied. Contact Progress Software Technical Support for guidance on available mitigations.
