Privilege escalation via insecure default admin permissions

Published Sep 12, 2023 · Updated Sep 26, 2024

Incorrect default permissions in Wing FTP Server 7.2.0 and earlier allow remote authenticated users to escalate Admin Web Client privileges. Public records identify insecure Admin Web Client permission defaults but do not disclose the affected permission, request, or operation. The CNA assessment requires high privileges and user interaction; exploitation exposes or changes administrative data without interrupting service.
