On Aug. 11, Moxa was contacted by ICS-CERT regarding security vulnerabilities of the ioLogik E1200 series remote I/O reported by Applied Risk. The four reported vulnerabilities are:

Suggested Mitigation

Item Vulnerability Type Impact
1 Multiple Stored Cross Site Scripting - XSS An authenticated user can execute arbitrary code from the web console.
2 Password sent via HTTP GET method In the HTTP web console, the password is not encrypted during the HTTP get request.
3 Password truncation With a brute force attack tool, it is possible to guess simple passwords. (e.g. password 12345678 or abcd1234)
4 Missing CSRF Protection An attacker may send requests by making a legitimate user click on a link.

Moxa recommends that customers should:

  • ? Use a firewall or a VPN tunnel to protect internet communication.
  • ? Minimize network exposure with strict access control to the control systems
  • ? Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
  • ? Enable the “Accessible IP List” feature of the ioLogik products to prevent any unauthorized access to the administrative web management interface
  • ? Set up strong passwords with a mix of special characters
  • ? Upgrade existing products after Moxa releases BETA or STD firmware
