Siemens Healthineers Products At Risk to Microsoft BlueKeep Wormable Vulnerability

There are six security advisories involving Siemens Healthineers products. The vulnerabilities have a CVSS v3 score of 9.8 out of 10 and may be linked to CVE-2019-0708, the Microsoft BlueKeep RDS vulnerability.

The vulnerability CVE-2019-0708 may be remotely exploited without user interaction. An attacker can exploit the vulnerability and take control of a vulnerable device by means of sending especially made requests to Remote Desktop Services on a vulnerable device through RDP.

The vulnerability is wormable and when exploited can propagate malware to vulnerable devices linked to a network just like in the WannaCry attacks in 2017. The seriousness of the vulnerability caused Microsoft to release patches for vulnerable operating systems, which include unsupported Windows versions that a lot of healthcare and industrial establishments still use.

The vulnerability impacts the following operating systems: Windows 2003, Windows XP, Windows 7, Windows Server 2008 and Windows Server 2008 R2. If it is not possible to apply the patch, RDP must be inactivated, Network Level Authentication (NLA) must be activated and port 3389 must be blocked at the firewall.

After Microsoft’s announcement of the RDS vulnerability and the issuance of the patches, Siemens investigated the affected Siemens Healthineers products and found 6 types of product to have vulnerabilities.

The vulnerability in these products may be exploited depending on the particular configuration and deployment setting. The vulnerabilities could typically be resolved when the Microsoft patch is applied. However, the patch may not be compatible with devices that are beyond their end-of-life. Customers using vulnerable devices can contact their local Siemens Healthineers customer support to get patch and remediation guidance.
