CVE-2023-40049Network attack vector

Unauthenticated file enumeration via WebServiceHost directory listing

Published Sep 27, 2023 · Updated Sep 24, 2024

Information disclosure in Progress Software Corporation WS_FTP Server before 8.8.2 allows remote attackers to enumerate files. The WebServiceHost directory listing is accessible without authentication and reveals file names that should remain unavailable to anonymous requests. Network access to the web component is sufficient; the published impact is file enumeration only, with no reported file-content disclosure or modification.
