NVD · unedited
Improper Validation of Certificate with Host Mismatch vulnerability in Hitachi Device Manager on Windows, Linux (Device Manager Server, Device Manager Agent, Host Data Collector components) allows Man in the Middle Attack.This issue affects Hitachi Device Manager: before 8.8.5-02.

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 confidence

Hitachi Device Manager fails to properly validate that certificates match the intended host, allowing an attacker to intercept communications via a Man in the Middle attack. The vulnerability exists in the Device Manager Server, Device Manager Agent, and Host Data Collector components on Windows and Linux platforms before version 8.8.5-02.

MitigationUpgrade Hitachi Device Manager to version 8.8.5-02 or later, which includes proper certificate host validation. Verify all communication channels use validated certificates post-upgrade.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Hitachi Device Manager components
    Locate Hitachi Device Manager installations on the system. Check for Device Manager Server, Device Manager Agent, and Host Data Collector components. On Windows, look in Program Files/Hitachi. On Linux, check /opt/hitachi or common installation directories. Use system inventory tools if available.
    Affected if Any Device Manager component (Server, Agent, or Host Data Collector) is installed on the system
  2. Determine the installed version of each component
    Open the installation directory of each found component and locate the version information. Common locations: version file, about dialog, or check the installer/logs. On Windows, you may also check Add/Remove Programs for the version. On Linux, check rpm/dpkg package information if installed via package manager.
    Affected if The detected version is lower than 8.8.5-02
  3. Verify if vulnerable components accept network connections
    Determine if the Device Manager components are configured to accept remote connections. Check configuration files for listener ports and network bindings. On Windows, review services to see if components run as network services. On Linux, check systemctl status or netstat/ss for listening ports.
    Affected if The component with a vulnerable version is exposed on the network and can accept connections from other hosts

If any installed Hitachi Device Manager component (Server, Agent, or Host Data Collector) is version 8.8.5-01 or earlier (lower than 8.8.5-02), the environment is affected by this certificate validation vulnerability.
