C-more EA9: Cleartext Transmission of Sensitive Information

Published Updated By the CyberSecBulletin desk

CVE-2022-2005 is a high-severity cleartext transmission of sensitive information vulnerability in C-more EA9 from AutomationDirect, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.73 as the first without the flaw, so updating C-more EA9 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.55% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update C-more EA9 to 6.73 or a later version.
  2. Update C-more Ea9-t6cl Firmware to 6.73 or a later version.
  3. Update C-more Ea9-t6cl-r Firmware to 6.73 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

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;

The underlying weakness: Cleartext Transmission of Sensitive Information

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

How developers prevent this class of flaw

  • Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
  • When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
  • When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
