CVE-2022-2513

Summary

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 and logs files. An attacker having get access to the exported backup file can exploit the vulnerability and obtain user credentials of the IEDs. Additionally, an attacker with administrator access to the PCM600 host machine can obtain other user credentials by analyzing database log files. 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/ to protect the host Operating System.
