Review – 2 Advisories and 1 Update Published – 10-31-23

Today, CISA’s NCCIC-ICS published two control system security advisories for products from Zavio and INEA. They also updated an advisory for products from Mitsubishi Electric.

There is a discrepancy in the advisory numbers published today, the two advisories end in -03 and -02, CISA apparently skipped -01. While this could be an editorial mistake, it could mean that CISA published the ‘-01’ advisory to limited distribution on the Homeland Security Information Network (HSIN). This happens when CISA or the vendor has concerns about allowing critical infrastructure facilities a chance to mitigate a vulnerability before it is published. See the Baker Hughes advisory publicly published on February 24^th, 2022.
