medium Tenable OT Security Plugin ID 500711

Synopsis

The remote OT asset is affected by a vulnerability.

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.

Hitachi Energy released the following recommended immediate actions:

- Update to PCM600 v2.11 Hotfix 20220923 or apply mitigation factors/workarounds

Hitachi Energy recommends the following steps to mitigate the risk of vulnerability exploitation:

- Implement the least privilege principle, continuously revising permissions and accesses to PCM600 related resources, including the backup file (a PCMI/PCMP file.)
- Use a firewall system with the minimal number of exposed ports to help protect a process control network from attacks originating from outside the network.
- Protect process control systems from direct, physical access by unauthorized personnel.
- Ensure process control systems are not directly connected to the internet.
- Separate process control systems from other networks via network segmentation techniques.
- Avoid using process control systems for browsing the internet, instant messaging, or receiving emails.
- Scan removable storage media for malware prior to connection to a process control system.
