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.
-
Verify Lenovo Enterprise Network Disk is installedCheck for the presence of Lenovo Enterprise Network Disk software on the system by looking for the application in installed programs (Windows Control Panel > Programs and Features) or checking for the application service/process runningAffected if The software is not installed or not found on the system
-
Determine the installed versionLocate the version information for Lenovo Enterprise Network Disk - typically found in the application itself (Help > About), in the Windows registry under the software's uninstall key, or in the program's installation directoryAffected if The installed version cannot be determined or the software is not found
-
Compare version against affected rangeCompare your installed version to the affected version 6.1 - check if it is exactly version 6.1 and identify the patch and hotfix level appliedAffected if The version is 6.1 without patch 6 hotfix 4 (or later) applied
-
Verify user authentication contextSince this XSS requires an authenticated session, confirm whether users access the application with credentials - note that exploitation only affects authenticated users who visit a crafted URLAffected if Users access Lenovo Enterprise Network Disk with authentication and the version is vulnerable
A user is affected if Lenovo Enterprise Network Disk version 6.1 is installed without patch 6 hotfix 4 (or later) and users access the application with authentication credentials.
