Official description
Passwords are not adequately encrypted during the communication process between all versions of LS Industrial Systems (LSIS) Co. Ltd LS Electric XG5000 software prior to V4.0 and LS Electric PLCs: all versions of XGK-CPUU/H/A/S/E prior to V3.50, all versions of XGI-CPUU/UD/H/S/E prior to V3.20, all versions of XGR-CPUH prior to V1.80, all versions of XGB-XBMS prior to V3.00, all versions of XGB-XBCH prior to V1.90, and all versions of XGB-XECH prior to V1.30.
