CVE-2021-41300
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 · uneditedECOA BAS controller’s special page displays user account and passwords in plain text, thus unauthenticated attackers can access the page and obtain privilege with full functionality.
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 ECOA BAS controller contains a special page that displays user account credentials in plaintext without requiring authentication. Unauthenticated remote attackers can access this page to retrieve valid username/password pairs, achieving full administrative privileges and complete system control.

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.
-
Confirm the device modelIdentify the Ecoa BAS controller model by checking the device label, web interface header, or SNMP sysDescr. Look for 'Ecs Router Controller', 'Riskbuster', or 'Riskterminator' in the product identification.Affected if The device is an Ecoa Ecs Router Controller, Ecoa Riskbuster, or Ecoa Riskterminator - all versions are affected.
-
Check firmware versionRetrieve the firmware version from the device's web interface, command line, or SNMP. Even though all versions are affected, document the installed version for the report.Affected if Any firmware version is present - the vulnerability affects all versions.
-
Locate the credential disclosure endpointExamine HTTP responses from the device's web interface for paths or parameters that may return user account data. The vulnerability involves a special page that exposes credentials.Affected if A page or API endpoint returns user account information without requiring authentication.
-
Verify authentication requirementAttempt to access the identified credential endpoint without providing any login credentials or session cookies. Observe whether the response contains user data.Affected if The endpoint returns credentials without any authentication token, session, or HTTP Basic Auth.
-
Check for plaintext passwordsExamine the response content from the credential endpoint. Look for password strings in cleartext rather than hashed or masked values.Affected if The response contains plaintext password strings associated with usernames.
If the device is an Ecoa Ecs Router Controller, Riskbuster, or Riskterminator and a page or endpoint returns user credentials without requiring authentication, the environment is affected by CVE-2021-41300.

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 dataRestrict access to the vulnerable page through proper authentication and authorization controls. Implement password masking and ensure credentials are stored and transmitted using strong encryption rather than plaintext.
