Siemens has identified two vulnerabilities in Siemens’ Molecular Imaging products running on Windows XP. Siemens is preparing updates for the affected products.
These vulnerabilities could be exploited remotely.
Siemens reports that the vulnerability affects the following products:
Successful exploitation of these vulnerabilities may allow the attacker to remotely execute arbitrary code.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment and specific clinical usage.
Siemens is an international company headquartered in Munich, Germany.
The affected products, Select Molecular Imaging products, are used in medical imaging. According to Siemens, Molecular Imaging products are deployed across the Healthcare and Public Health sector. Siemens estimates that these products are used worldwide.
An unauthenticated remote attacker could execute arbitrary code via a specially crafted remote procedure call (RPC) request sent to the server service of affected Microsoft Windows systems.

This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).CVSS Calculator, https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, web site last accessed August 03, 2017.
These vulnerabilities could be exploited remotely.
No known public exploits specifically target these vulnerabilities.
An attacker with a low skill would be able to exploit these vulnerabilities.
Siemens is preparing updates for the affected products and recommends protecting network access to the Molecular Imaging products with appropriate mechanisms. It is advised to run the devices in a dedicated network segment and protected IT environment. If this is not possible, Siemens recommends the following:
In addition, Siemens recommends:
