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
Optergy Proton/Enterprise devices have Hard-coded 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 · moderate confidence

Optergy Proton and Enterprise building management system devices contain hard-coded credentials embedded in the firmware or configuration. These credentials can be extracted or guessed, allowing unauthorized attackers to gain administrative access to the affected devices.

MitigationReplace all default/hard-coded credentials with unique, strong credentials per device, apply any available vendor firmware updates that remove hard-coded accounts, and implement a credential management policy to prevent future hard-coded credentials in deployed systems.

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 Optergy product and version
    Access the device management interface or check system information to determine if the device is running Optergy Proton or Enterprise and note the firmware/software version number
    Affected if The installed version is Optergy Proton or Enterprise and the version is 2.3.0a or lower
  2. Verify default administrative accounts
    Check the list of user accounts configured in the system, specifically looking for default administrative usernames that ship with the product
    Affected if Default administrative accounts (such as 'admin' or other factory-default accounts) are present and active on the system
  3. Test for hard-coded credentials
    Attempt to authenticate using known default credential pairs or check configuration files for hard-coded password strings
    Affected if Authentication succeeds with any default or hard-coded credential that should have been changed post-deployment
  4. Review credential configuration
    Inspect the authentication configuration or user management settings to determine if passwords are stored in plain text or use weak/default values
    Affected if Credentials are set to default values or hard-coded passwords are found in configuration

The environment is affected if the installed Optergy Proton or Enterprise version is 2.3.0a or lower and any default or hard-coded administrative credentials are still active on the system.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

From vendor data
Upgrade available Upgrade to a release after 2.3.0a
Interim mitigation

Replace all default/hard-coded credentials with unique, strong credentials per device, apply any available vendor firmware updates that remove hard-coded accounts, and implement a credential management policy to prevent future hard-coded credentials in deployed systems.
