CVE-2021-27414
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 · uneditedAn attacker could trick a user of Hitachi ABB Power Grids Ellipse Enterprise Asset Management (EAM) versions prior to and including 9.0.25 into visiting a malicious website posing as a login page for the Ellipse application and gather authentication credentials.
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 confidenceThis is a phishing vulnerability where attackers create a malicious website mimicking the Ellipse EAM login page to steal user credentials. The affected versions (prior to and including 9.0.25) lack sufficient protection against credential theft from phishing attacks, such as multi-factor authentication or certificate-based client authentication.

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 the installed Ellipse EAM versionAccess the Ellipse EAM application and navigate to the About or System Information section, typically found in the administrator console or help menu. Alternatively, check the installation directory for version metadata files or contact your system administrator for version details.Affected if The installed version is lower than 9.0.23 (or 9.0.25 based on summary) as this indicates the application lacks enhanced anti-phishing protections.
-
Verify if Multi-Factor Authentication (MFA) is enabledLog into the Ellipse EAM administration console and navigate to Security or Authentication settings. Look for MFA, Two-Factor Authentication, or Multi-Factor Authentication configuration options.Affected if MFA is disabled or not configured, meaning stolen credentials alone could be used by phishing attackers.
-
Verify if certificate-based client authentication is configuredIn the Ellipse EAM security settings, check for client certificate authentication, PKI authentication, or hardware token configuration options. This may require examining the SSL/TLS settings or authentication method configurations.Affected if Certificate-based client authentication is not enabled, leaving the login vulnerable to credential phishing attacks.
You are affected if your Ellipse EAM version is below 9.0.23 and neither MFA nor certificate-based client authentication is enabled in your environment.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped9.0.23
Implement multi-factor authentication (MFA) to prevent stolen credentials from being usable, and deploy certificate-based or hardware token authentication to verify legitimate users. Additionally, conduct user security awareness training to recognize phishing attempts.
Version 9.0.26 or later (contact vendor for exact latest fixed release)
- 1. Identify the current version of Ellipse Enterprise Asset Management installed in your environment
- 2. Contact Hitachi ABB Power Grids or ABB to obtain the latest security patch or fixed release
- 3. Review release notes and documentation for the fixed version to understand changes
- 4. Schedule a maintenance window for the upgrade process
- 5. Perform a full backup of the Ellipse EAM system and database
- 6. Test the upgrade in a non-production environment first
- 7. Apply the upgrade following vendor-provided installation instructions
- 8. Verify the application functions correctly after upgrade
