CVE-2023-51948Public exploitNetwork attack vector

File enumeration via exposed /fm directory index

Published Jan 19, 2024 · Updated Jun 20, 2025

Directory listing in actidata actiNAS SL 2U-8 RDX 3.2.03-SP1 allows remote attackers to enumerate files through the /fm endpoint. An unauthenticated request to /fm returns an index of the web application's directory structure instead of denying access. No credentials or user interaction are required, and the documented impact is disclosure of file names and paths rather than file modification or service interruption.
