CVE-2021-32528
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedObservable behavioral discrepancy vulnerability in QSAN Storage Manager allows remote attackers to obtain the system information without permissions. Suggest contacting with QSAN and refer to recommendations in QSAN Document.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAn observable behavioral discrepancy vulnerability in QSAN Storage Manager allows remote unauthenticated attackers to obtain sensitive system information. This information disclosure occurs due to a flaw in how the system responds or behaves when queried without proper authentication, likely through inconsistent responses between authenticated and unauthenticated states.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if QSAN Storage Manager is installedCheck for QSAN Storage Manager processes or services running on the system. Look for processes named 'StorageManager', 'QSAN' or related services. On Windows, check Services for QSAN-related entries. On Linux, use 'ps aux | grep -i qsan' or check for installation directories under /opt/qsan or similar.Affected if QSAN Storage Manager is found running on the system
-
Determine the installed version of QSAN Storage ManagerLocate the version information. Check the application GUI About section if accessible, or look for version files in the installation directory. Common locations include: installation folder documentation, or the management interface login page source. Compare your version to the affected range: <= 3.3.1Affected if The installed version is 3.3.1 or lower
-
Check if the QSAN management interface is network-accessibleDetermine if the QSAN Storage Manager web interface port (typically ports 443, 8443, or 8080) is listening and exposed to network accessible IP addresses. Use 'netstat -an | grep -E "(443|8080|8443)"' or similar port scanning tools to identify listening services.Affected if The management interface is exposed to untrusted networks or the internet
-
Test unauthenticated endpoint responses for behavioral discrepancySend unauthenticated HTTP requests to common QSAN API endpoints (such as /api/system/info, /api/login, or the login page) and observe the response. Compare responses to identify if sensitive system information (device names, serial numbers, firmware version, disk status, or configuration details) is returned without authentication.Affected if The system returns sensitive system information or different error/response messages to unauthenticated requests compared to expected unauthenticated behavior
A user is affected if QSAN Storage Manager version 3.3.1 or lower is installed and its management interface returns sensitive system information to unauthenticated requests.
