Noam Moshe of Claroty Research, working with Trend Micro Zero Day Initiative, reported this vulnerability to CISA.
ICONICS and Mitsubishi Electric recommend updating the ICONICS Suite software with the latest security patches when available (login required). Security updates are released as critical fixes or rollup releases.
ICONICS and Mitsubishi Electric recommend users take the following mitigation steps:
- Locate control system networks and devices behind firewalls and isolate them from untrusted networks and hosts.
- Minimize network exposure for all control system devices. Control system devices should not directly face the internet.
- Avoid clicking on web links in emails or opening email attachments from untrusted sources.
- For systems without patches or fixes, users should:
- Only unpack files received from trusted sources.
- Protect and encrypt Pack&Go packages with a password to prevent modifications by untrustworthy users.
- Avoid unpacking a Pack&Go package file using a relative path (Note: this would show in the Workbench UI).
Users should refer to the ICONICS whitepaper on security vulnerabilities for information on security update availability.
Refer to the Mitsubishi Electric advisory for further details and instructions for determining installed versions.
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
