-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 # SSA-187667: DejaBlue Vulnerabilities - Siemens Healthineers Products Publication Date: 2019-09-10 Last Update: 2019-09-10 Current Version: 1.0 CVSS v3.0 Base Score: 9.8 SUMMARY ======= Microsoft has released updates for several versions of Microsoft Windows, which fix vulnerabilities in the Remote Desktop Service that are discussed under the name DejaBlue. The vulnerabilities could allow an unauthenticated remote attacker to execute arbitrary code on the target system if the system exposes the service to the network. All Siemens Healthineers products from all business lines have been evaluated. Most Siemens Healthineers products are not affected by the vulnerabilities because they do not provide the option to activate the Remote Desktop Service, implement other controls that mitigate the vulnerabilities, use a version of Microsoft Windows that is not affected, or are not based on Microsoft Windows. This advisory provides a full list of affected products from Siemens Healthineers and provides recommendations to mitigate the vulnerabilities.

WORKAROUNDS AND MITIGATIONS =========================== Siemens Healthineers has identified the following specific workarounds and mitigations that customers can apply to reduce the risk: * Contact Siemens Healthineers Service Technician to obtain information if Remote Desktop Protocol (RDP) on the product can be disabled to mitigate the risk * For Siemens Healthineers products that install on customer computers, customers are strongly recommended to secure those computers as soon as possible with the appropriate patches from Microsoft * If possible, block port 3389/tcp on an external firewall * Secure the surrounding environment according to the recommendations provided by Microsoft which can be found here: * https://msrc-blog.microsoft.com/2019/08/13/patch-new-wormable-vulnerabilities-in-remote-desktop-services-cve-2019-1181-1182/ * https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1181 * https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1182 * https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1222 * https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1226 GENERAL SECURITY RECOMMENDATIONS ================================ In addition, Siemens Healthineers recommends the following: - - Ensure you have appropriate backups and system restoration procedures. - - For specific patch and remediation guidance information, contact your local Siemens Healthineers customer service engineer, portal or our Regional Support Center. VULNERABILITY CLASSIFICATION ============================ The vulnerability classification has been performed by using the CVSS scoring system in version 3.0 (CVSS v3.0) (https://www.first.org/cvss/). The CVSS environmental score is specific to the customer's environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring. * Vulnerability CVE-2019-1181 An unauthenticated attacker with access to port 3389/tcp in an affected device may execute arbitrary commands with elevated privileges.
