Philips recommends users update to the newest version to mitigate a use of hard-coded password and download of code without integrity check vulnerabilities in its IntelliVue M3002A X2 MMS Transport Monitor/Module and IntelliVue MP monitors (MP2/X2, MP5, MP20-MP90, MX600, MX700 and MX800), according to a report with CISA.

Successful exploitation of these vulnerabilities, discovered by Shawn Loveric of Finite State, Inc., may cause corruption of the IntelliVue WLAN firmware and impact to the data flow over the WLAN Version A and WLAN Version B wireless modules. This would lead to an inoperative condition alert at the device and Central Station.

The following versions of Philips IntelliVue WLAN, portable patient monitors, suffer from the vulnerabilities:
• IntelliVue MP monitors MP20-MP90 (M8001A/2A/3A/4A/5A/7A/8A/10A)
WLAN Version A, Firmware A.03.09
• IntelliVue MP monitors MP5/5SC (M8105A/5AS)
WLAN Version A, Firmware A.03.09, Part #: M8096-67501
• IntelliVue MP monitors MP2/X2 (M8102A/M3002A)
WLAN Version B, Firmware A.01.09, Part #: N/A (Replaced by Version C)
• IntelliVue MP monitors MX800/700/600 ((865240/41/42)
WLAN Version B, Firmware A.01.09, Part #: N/A (Replaced by Version C)

In one vulnerability, an attacker can use these credentials to login via ftp and upload a malicious firmware.

Cyber Security

CVE-2019-13530 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 6.4.

In addition, the product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.

CVE-2019-13534 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 6.4.

The product sees use mainly in the healthcare and public health sectors. It also sees action on a global basis.

No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely. High skill level is needed to exploit.

WLAN Version B is obsolete. Philips recommends users update to the WLAN assembly Version C wireless module in affected IntelliVue monitors.

WLAN Version C with current firmware of B.00.31 is not vulnerable to the described attack.

WLAN Version A is a software patch from Philips estimated to be available in Incenter by the end of 2019.

Wireless network access should be controlled by authentication and authorization (e.g., WPA2), which are supported by Philips.

As an additional mitigation measure, Philips recommends implementing a firewall rule on the user’s wireless network to restrict access control via FTP. Users should implement role-based access controls to control physical access to the system. Refer to the Security for Clinical Networks Guide and the IntelliVue Network Configuration Guide for additional security recommendations.
