Default credentials and no authentication within third party software may allow an attacker to compromise a component of the system.
CVE-2018-17906 has been assigned to this vulnerability. A CVSS v3 base score of 6.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).
A user reported this vulnerability to Philips, who then reported it to NCCIC.
Philips recommends that users ensure IntelliSpace PACS installations run in a managed service environment that adheres to NCCIC recommendations to minimize the risk of exploitation (Virtual Private Network, Firewall isolation from other networks, no Internet access). In addition, Philips employs an automated Antivirus solution that continuously monitors and remediates threats across all systems in the managed service environment. Philips has a monthly recurring patch program which all IntelliSpace PACS users are encouraged to participate. Users who participate in this program receive all Philips approved operating system and application patches in a timely fashion. The Philips iSite 3.6 platform is currently at its end of life (EoL) and end of service (EoS).
As an interim mitigation to the vulnerability, Philips recommends that users:
Philips will continue to add cybersecurity vulnerability remediation improvements through their secure development lifecycle (SDL) as threats continue.
