9.1 CRITICALPublished 2026-10-29 · Updated 2026-10-30
AI risk analysis
- Summary
- A delegated Host Administrator in Progress WS_FTP Server (pre-2024.0.7 and pre-2025.0.4) lacks proper authorization checks in the admin interface, allowing them to escalate privileges and execute arbitrary commands with full server compromise.
- Exploitability
- Exploitation requires valid credentials for a delegated Host Administrator role and access to the vulnerable administrative interface; no public exploit exists.
- Blast radius
- Successful exploitation grants full control of the underlying Windows server, enabling data theft, lateral movement, and persistent backdoor deployment.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to WS_FTP Server version 2024.0.7 or 2025.0.4 immediately.
