Two Advisories Published – 01-22-19

Today the DHS NCCIC-ICS published a control system security advisory for products from Johnson Controls and a medical device security advisory for products from Drager.

Johnson Controls Advisory

This advisory describes two vulnerabilities in the Johnson Controls Facility Explorer. The vulnerabilities were reported by Tridium. Johnson Controls has new versions that mitigate the vulnerabilities. There is no indication that Tridium has been provided an opportunity to verify the efficacy of the fix.

The two reported vulnerabilities are:

• Path traversal - CVE-2017-16744; and

• Improper authentication - CVE-2017-16748

NCCIC-ICS reports that an uncharacterized attacker could remotely exploit these vulnerabilities to allow an attacker to read, write, and delete sensitive files to gain administrator privileges in the Facility Explorer system.

Drager Advisory

This advisory describes three vulnerabilities in the Drager Infinity Delta patient monitoring devices. The vulnerabilities were reported by Marc Ruef and Rocco Gagliardi, of scip AG. Drager has new versions that mitigate the vulnerabilities. There is no indication that the researchers have been provided an opportunity to verify the efficacy of the fix.

The three reported vulnerabilities are:

• Improper input validation - CVE-2018-19010;

• Information exposure through log files - CVE-2018-19014; and

• Improper privilege management - CVE-2018-19012

NCCIC-ICS reports that a relatively low-skilled attacker with uncharacterized access could exploit the vulnerabilities to cause information disclosure of device logs, denial of service through device reboots of the patient monitors, and privilege escalation.

NOTE: The Drager security advisory adds an additional vulnerability for one of the affected products; “Several 3rd party components were found outdated and vulnerable to several published security vulnerabilities.”
