CVE-2021-27437
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 · uneditedThe affected product allows attackers to obtain sensitive information from the WISE-PaaS dashboard. The system contains a hard-coded administrator username and password that can be used to query Grafana APIs. Authentication is not required for exploitation on the WISE-PaaS/RMM (versions prior to 9.0.1).
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 confidenceThe WISE-PaaS dashboard contains hard-coded administrator credentials embedded in the system that can be used to query Grafana APIs without authentication. This allows unauthenticated attackers to obtain sensitive information from the dashboard.

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 WISE-PaaS/RMM versionCheck the system or dashboard for the version number of WISE-PaaS/RMM installed in your environment. This is typically visible in the dashboard UI header, system information page, or version configuration file.Affected if The installed version is below 9.0.1
-
Locate hard-coded credentials in dashboard configurationInspect configuration files, environment variables, or embedded scripts within the WISE-PaaS dashboard installation for hard-coded username and password pairs, particularly those associated with administrative accounts.Affected if Hard-coded administrator credentials are found embedded in configuration files or source code
-
Test Grafana API without authenticationAttempt to access Grafana API endpoints (such as /api/dashboards, /api/users, or /api/org) on the WISE-PaaS dashboard server using HTTP requests without providing any authentication credentials.Affected if The API returns sensitive dashboard data, user information, or organizational details without requiring authentication
Your environment is affected if you are running WISE-PaaS/RMM version below 9.0.1 and either hard-coded credentials are present in your configuration or the Grafana API is accessible without authentication.
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 · scoped9.0.1
Upgrade WISE-PaaS/RMM to version 9.0.1 or later, and immediately rotate any exposed hard-coded credentials. Implement proper authentication mechanisms and remove embedded credentials from the codebase.
9.0.1 or later
- Upgrade WISE-PaaS/RMM to version 9.0.1 or later to remediate the hard-coded credentials vulnerability
- After upgrading, verify that the hard-coded credentials have been removed from the system
- Change any default credentials that may still be present and implement strong, unique passwords for administrative accounts
- Confirm that authentication is now required for accessing the Grafana APIs and WISE-PaaS dashboard
