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
AutomationDirect C-more EA9 HTTP webserver uses an insecure mechanism to transport credentials from client to web server, which may allow an attacker to obtain the login credentials and login as a valid user. This issue affects: AutomationDirect C-more EA9 EA9-T6CL versions prior to 6.73; EA9-T6CL-R versions prior to 6.73; EA9-T7CL versions prior to 6.73; EA9-T7CL-R versions prior to 6.73; EA9-T8CL versions prior to 6.73; EA9-T10CL versions prior to 6.73; EA9-T10WCL versions prior to 6.73; EA9-T12CL versions prior to 6.73; EA9-T15CL versions prior to 6.73; EA9-RHMI versions prior to 6.73; EA9-PGMSW versions prior to 6.73;

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
How this class of weakness works · CWE-319

Sensitive information is transmitted over an unencrypted channel, so anyone positioned on the network path can read it as it passes. Credentials, tokens, and personal data are the usual casualties. The fix is to encrypt everything sensitive in transit with TLS and to remove any plaintext fallback.

General guidance for the cleartext transmission class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

Recommended fix High confidence

Firmware version 6.73

  1. Check the current firmware version of the C-more EA9 HMI device through the device's web interface or system settings
  2. Download the firmware version 6.73 or later from the official AutomationDirect support website or through the CISA advisory icsa-22-167-01
  3. Follow the manufacturer's firmware update instructions specific to your EA9 model to apply the update
  4. After updating, verify the firmware version has been successfully changed to 6.73 or later
  5. Confirm that the webserver now uses secure credential transmission (HTTPS) instead of HTTP
