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 QSAN Storage Manager versionLocate the installed version of QSAN Storage Manager by checking the application interface, version file, or management console. Compare the found version against the affected range (versions prior to 3.3.3).Affected if Installed version is lower than 3.3.3
-
Confirm share_link function is presentIdentify whether the share_link function module exists in the QSAN Storage Manager installation by examining the web application endpoints or API structure.Affected if The share_link function is present and enabled in the installation
-
Verify web interface accessibilityDetermine if the QSAN Storage Manager web interface is accessible over the network by checking the listening services and network exposure of the management ports.Affected if The web interface is exposed and reachable without authentication
-
Test directory listing via share_linkIf the vulnerable endpoint exists, attempt to access an arbitrary directory path through the share_link parameter to confirm the directory listing capability is present.Affected if The share_link endpoint allows traversal to arbitrary directories without authentication
A user is affected if QSAN Storage Manager version is below 3.3.3 AND the share_link web endpoint is accessible, allowing unauthenticated directory listing that could expose sensitive credential files.
