May 2018 Security Update
If a user tries to log in with a username that does not exist in that RTU’s user database, one of the web server tasks would crash. There are 5 web server tasks running in the RTU so after five failed attempts, the RTU would need to be rebooted for the Web GUI to function properly. All SCADA / RTU functionality will continue to work properly, just the configuration interface was affected.
This only affects RTU’s running the C3414-500-S02K2_P3 firmware, so we advise anyone running this firmware to update to C3414-500-S02K2_P4.
