title: Cleartext Credentials Vulnerability on Hitachi Energy’s Multiple IED Connectivity Packages (IED ConnPacks) and PCM600 Products
description: A vulnerability exists in the Intelligent Electronic Device (IED) Connectivity Package (ConnPack) credential storage function in Hitachi Energy’s PCM600 product included in the versions listed below, where IEDs credentials are stored in a cleartext format in the PCM600 database. An attacker who manages to get access to the exported backup file can exploit the vulnerability and obtain credentials of the IEDs. The credentials may be used to perform unauthorized modifications such as loading incorrect configurations, reboot the IEDs or cause a denial-of-service on the IEDs.

workarounds:
It is recommended to implement and continuously revise least privileges principles to minimize permissions and
accesses to PCM600 related resources, included the backup file, PCMI/PCMP file.
Recommended security
practices and firewall configurations can help protect a process control network from attacks that originate from
outside the network. Such practices include that process control systems are physically protected from direct
access by unauthorized personnel, have no direct connections to the Internet, and are separated from other
networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be
evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or
receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses
before they are connected to a control system.
An additional recommendation is to follow the hardening guidelines published by “The Center for Internet Security
(CIS)”  https://www.cisecurity.org/about-us/ https://www.cisecurity.org/about-us/  to protect the host Operating System.
