CVE-2021-41302
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 stores sensitive data (backup exports) in clear-text, thus the unauthenticated attacker can remotely query user password and obtain user’s privilege.
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 confidenceThe ECOA BAS controller stores backup exports containing sensitive data (including user passwords) in plaintext, allowing an unauthenticated remote attacker to query these backups and obtain credentials, thereby gaining elevated privileges on the system.

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.
-
Verify backup export functionality is enabledAccess the ECOA BAS controller web interface or check device configuration for backup export settings. Look for options like 'Backup', 'Export Configuration', or 'Save Configuration' in the admin panel.Affected if Backup export feature is enabled and configured on the device
-
Check backup endpoint accessibilityAttempt to access common backup-related URLs on the device (such as /backup, /export, /config, or similar endpoints) without providing any credentials. Use a web browser or curl command to test HTTP/HTTPS responses.Affected if Backup endpoints respond without requiring authentication (HTTP 200 OK without login)
-
Inspect backup file for plaintext sensitive dataIf a backup file is accessible, download it and examine the contents using a text editor or strings command. Search for patterns like 'password', 'user', 'admin', or look for plaintext credential strings.Affected if The backup file contains plaintext usernames and passwords or other sensitive configuration data
-
Verify network exposure of the BAS controllerCheck if the ECOA device is directly accessible from external networks or the internet. Use network scanning tools (nmap) or check firewall rules to determine if ports serving the web interface are exposed publicly.Affected if The BAS controller management interface is reachable from untrusted networks without VPN or authentication barriers
If backup exports can be retrieved without authentication and contain plaintext credentials, the environment is affected by this vulnerability.

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 dataImplement encryption for backup exports, enforce authentication on backup retrieval endpoints, and restrict network access to the BAS controller to prevent unauthorized remote access.
