End Update A Part 6 of 6 -Д¬ISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Begin Update A Part 6 of 6 -ДЇor more information on these vulnerabilities and more detailed mitigation instructions, please see Siemens security advisory SSA-761617 and the PKE security advisory. In order to operate the devices in a protected IT environment, Siemens recommends configuring the environment according to SiemensвЂ™ operational guidelines for industrial security and to following the recommendations in the product manuals.ДЄdditional information on industrial security by Siemens can be found at: End Update A Part 5 of 6 -ДЄs a general security measure, Siemens strongly recommends protecting network access to devices with appropriate mechanisms.

CVE-2019-18340 - Harden the Video Servers to prevent local access by unauthorized users.

CVE-2019-18339 - SiNVR/SiVMS deployments with active Control Center Server (CCS) should ensure that every video server and client have the Authorization Server set to вЂњControl Center ServerвЂќ (Configuration -> Appearance -> Desktop -> Authorization Server).

Harden all systems accordingly to prevent unauthorized access.

General (applies to all vulnerabilities listed in this advisory) вЂ“ Apply ACL/firewall configuration on the Video Servers to ensure that only legitimate systems can access the configured server ports.

Siemens has identified the following specific workarounds and mitigations that users can apply to reduce the risk: Siemens recommends users to update to v5.0.0 or later. RaphaГ«l Rigo from Airbus Security Lab reported these vulnerabilities to Siemens.
