CVE-2021-32519
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 · uneditedUse of password hash with insufficient computational effort vulnerability in QSAN Storage Manager, XEVO, SANOS allows remote attackers to recover the plain-text password by brute-forcing the MD5 hash. The referred vulnerability has been solved with the updated version of QSAN Storage Manager v3.3.2, QSAN XEVO v2.1.0, and QSAN SANOS v2.1.0.
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 · high confidenceQSAN Storage Manager, XEVO, and SANOS store password hashes using MD5, a cryptographically broken algorithm with insufficient computational effort. Remote attackers who obtain these hashes can easily brute-force them to recover plaintext passwords, enabling unauthorized access.

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 the installed QSAN productLog into the QSAN management interface or check system documentation to determine whether the deployment uses Storage Manager, XEVO, or SANOS.Affected if Any of these three products is in use
-
Check the Storage Manager versionIn the Storage Manager web interface, navigate to Settings > System > About, or check the installer package version. The version is typically displayed as a three-part number like x.y.z.Affected if Version is below 3.3.2
-
Check the Xevo versionIn the Xevo management console, locate the version information under System Information or the About section. The version number is shown in the UI or can be retrieved via the CLI if available.Affected if Version is below 2.1.0
-
Check the SANOS versionAccess the SANOS command line or check the firmware information through the storage controller interface. The SANOS version is displayed in the system overview or boot messages.Affected if Version is below 2.1.0
If the identified QSAN product version falls below 3.3.2 for Storage Manager, 2.1.0 for XEVO, or 2.1.0 for SANOS, then the environment stores password hashes using the vulnerable MD5 algorithm and is affected.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data2.1.03.3.2
Update affected QSAN products to their patched versions: Storage Manager v3.3.2, XEVO v2.1.0, and SANOS v2.1.0. Additionally, enforce strong password policies and consider password rotation for any accounts that may have been compromised.
