CVE-2021-32511Network attack vector

Directory-content disclosure via unchecked file path

Published Jul 7, 2021 · Updated Sep 16, 2024

Directory listing in QSAN Storage Manager 3.3.1 and earlier allows remote authenticated users to list arbitrary directories via ViewBroserList. The function accepts a file path parameter and enumerates the requested directory without restricting the request to authorized paths. A general user account is sufficient, and the consequence is limited to disclosure of directory contents rather than modification or service interruption.
