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 · uneditedIncorrect Default Permissions vulnerability in Hitachi Storage Plug-in for VMware vCenter allows local users to read and write specific files. This issue affects Hitachi Storage Plug-in for VMware vCenter: from 04.0.0 through 04.9.2.
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 confidenceThe Hitachi Storage Plug-in for VMware vCenter versions 04.0.0 through 04.9.2 ships with overly permissive default file permissions on specific files. Local users with standard account access can read and write to these files, potentially allowing privilege escalation or access to sensitive configuration/data.

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 Hitachi Storage Plug-in for VMware vCenter is installedLocate the plugin installation directory on the vCenter server. Common paths include /opt/vmware/vcops/vcopsIntegration/ or C:\Program Files\VMware\vCenter Server\extensions\ on Windows. Check for directories containing 'Hitachi' or 'HDS' in the name.Affected if The plugin is present on the system
-
Determine the installed plugin versionCheck the plugin version by reviewing version files in the installation directory, or run the plugin's version command if available (for example, examine the manifest.xml or version.info file within the plugin directory).Affected if The version is 04.0.0 through 04.9.2 (any version < 04.10.0)
-
Inspect file permissions on plugin filesUse 'ls -la' (Linux) or icacls (Windows) to list permissions on the plugin installation directory and its contents. Look for files with permissions allowing read or write access to standard (non-admin) users or 'Everyone' group.Affected if Files grant read or write access to standard user accounts or overly broad groups
The environment is affected if the Hitachi Storage Plug-in for VMware vCenter is installed with a version between 04.0.0 and 04.9.2 and has files with overly permissive access controls.
