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 · uneditedMissing Password Field Masking vulnerability in Hitachi Device Manager on Windows, Linux (Device Manager Agent component).This issue affects Hitachi Device Manager: before 8.8.5-04.
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 confidenceHitachi Device Manager Agent on Windows and Linux contains a UI vulnerability where password fields do not mask user input, causing credentials to be displayed in plaintext during entry. This allows physical observers or screen capture tools to capture sensitive authentication credentials.

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 installed Hitachi Device Manager versionCheck the application version through the installed software listing (Windows: Programs and Features, Linux: rpm -qa or dpkg -l) or look for version information in the application directoryAffected if Version is lower than 8.8.5-04
-
Locate Device Manager installation directoryCommon paths include C:\Program Files\Hitachi\DeviceManager (Windows) or /opt/hitachi/devicemanager (Linux). Check installation documentation or use file search for Device Manager executablesAffected if Installation directory exists and contains vulnerable version
-
Verify version in product-specific locationCheck for version.info, version.txt, or similar file within the installation directory, or run the application with --version flag if availableAffected if Version file or output shows a build/version below 8.8.5-04
-
Confirm password field behavior (if accessible)Launch the Device Manager agent UI and observe login or authentication screens. If passwords appear as readable text rather than masked dots/circles during entry, the vulnerability is presentAffected if Password input fields display plaintext characters during entry
If the installed Hitachi Device Manager version is below 8.8.5-04, the environment is affected by the plaintext password display vulnerability.
