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 · unedited
An attacker could exploit this vulnerability in Hitachi ABB Power Grids Ellipse Enterprise Asset Management (EAM) versions prior to and including 9.0.25 by tricking a user to click on a link containing malicious code that would then be run by the web browser. This can result in the compromise of confidential information, or even the takeover of the user’s session.

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 confidence

Cross-site scripting (XSS) vulnerability in Hitachi ABB Power Grids Ellipse EAM web application where malicious JavaScript can be injected via crafted URLs, allowing attackers to execute arbitrary code in authenticated users' browser sessions and potentially hijack sessions or steal confidential data.

MitigationUpgrade Ellipse EAM to a version beyond 9.0.25 (vendor patch), or implement robust input validation and output encoding in the web application to neutralize malicious script injection.

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. Confirm Ellipse EAM installation
    Identify whether the Hitachi Energy Ellipse Enterprise Asset Management web application is deployed in your environment. Check your application inventory or consult with your IT asset management system for systems named Ellipse EAM or Ellipse Enterprise Asset Management.
    Affected if The system is running Hitachi Energy Ellipse Enterprise Asset Management
  2. Locate the version information
    Access the Ellipse EAM web interface and navigate to the About, System Information, or Help sections typically found in the application menu. Alternatively, check installation documentation or contact the system administrator for the deployed version number.
    Affected if The installed version cannot be determined or verified
  3. Compare version against affected range
    Compare your installed Ellipse EAM version number to the affected range: versions prior to 9.0.26 are vulnerable. Version 9.0.26 and later (including 9.0.26 itself) are not affected by this CVE.
    Affected if The installed version is lower than 9.0.26 (for example, 9.0.25, 9.0.24, 8.x, or earlier)
  4. Assess web exposure
    Determine if the Ellipse EAM web interface is accessible to users or external attackers. This XSS vulnerability is exploitable through crafted URLs, so confirm whether the web application is accessible over HTTP/HTTPS.
    Affected if The Ellipse EAM web interface is exposed and the version is below 9.0.26

You are affected if your environment runs Hitachi Energy Ellipse Enterprise Asset Management with a version lower than 9.0.26 and the web interface is accessible to users who could encounter crafted malicious URLs.

dbcve · scoped
Upgrade available Upgrade to 9.0.26 or later
Fixed in 9.0.26
Interim mitigation

Upgrade Ellipse EAM to a version beyond 9.0.25 (vendor patch), or implement robust input validation and output encoding in the web application to neutralize malicious script injection.

Recommended fix High confidence

Ellipse Enterprise Asset Management 9.0.26

  1. Obtain Ellipse Enterprise Asset Management version 9.0.26 or later from the official ABB vendor channels
  2. Review the release notes for version 9.0.26 to understand changes and any prerequisites
  3. Perform a full backup of the current Ellipse EAM system, including database and configuration files
  4. Schedule a maintenance window for the upgrade process
  5. Apply the upgrade to the Ellipse EAM system following ABB's official upgrade documentation
  6. After upgrade, verify the version number has been updated to 9.0.26 or later
  7. Validate that the XSS vulnerability is no longer present by testing with the previously malicious links
Caveat Review ABB release notes for any configuration or compatibility changes between your current version and 9.0.26
