Successful exploitation of these vulnerabilities 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, are affected:
CVE-2019-13530 has been assigned to this vulnerability. A CVSS v3 base score of 6.4 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H).
CVE-2019-13534 has been assigned to this vulnerability. A CVSS v3 base score of 6.4 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H).
Shawn Loveric of Finite State, Inc., reported these vulnerabilities to Philips.
WLAN Version B is obsolete.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 userβs 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.
