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.
-
Confirm QSAN Storage Manager is installedLocate the QSAN Storage Manager application or service on the system. Check for installation directories (typically under C:\Program Files\QSAN or C:\Program Files (x86)\QSAN on Windows, or /opt/qsan/ on Linux). Verify the software is present and operational.Affected if QSAN Storage Manager software is found running on the system
-
Identify installed versionAccess the management web interface and navigate to System > About, or check the installed program's version information. The version is typically displayed in the GUI footer or in the Help/About section. If command-line access is available, check the installation directory for a version file or use system inventory tools.Affected if The installed version is lower than 3.3.3 (e.g., 3.3.2, 3.3.1, 3.3.0, or earlier)
-
Verify QuickInstall component accessibilityThe QuickInstall feature is typically accessed via the web management interface at /quickinstall or similar paths. Check if the QSAN web management port (commonly 443, 8080, or 8443) responds to requests. Attempt to access the QuickInstall endpoint or check the web server configuration for mappings to this component.Affected if The QuickInstall web interface is exposed and reachable on the network
The environment is affected if QSAN Storage Manager version is lower than 3.3.3 and the QuickInstall component is accessible, allowing remote attackers to inject commands through the web interface.
