Two weeks ago, when Siemens released the advisory, there were no known public exploits for specifically targeting these vulnerabilities.

Siemens also advises implementing Defense-in-Depth, as outlined in the device system manual.

“The LOGO!8 BM manual recommends protecting access to Port 10005/TCP,” ICS CERT noted. They are an important component in a holistic industrial security concept.

CVE-2019-10921 – Storing passwords in a recoverable (cleartext) format (stored in the project).Īll versions of Siemens LOGO!8 BM (basic module) are affected.Īs confirmed by Siemens Siemens, all three vulnerabilities can be exploited by an unauthenticated attacker with network access to port 10005/tcp, with no user interaction. DOCOSS-Siemens74.pdf DOCOSS-CP1243-1DNP376.pdf Security information Siemens provides automation and drive products with industrial security functions that support the secure operation of plants or machines.

CVE-2019-10920 – Use of hard-coded cryptographic key (the aforementioned configured passwords are, for example, encrypted with it).

CVE-2019-10919 – Missing authentication for critical functions (getting profile information containing sensitive data such as different configured passwords, setting passwords) which could allow the attacker to perform device reconfigurations and obtain project files.

The vulnerabilities, discovered and reported by Manuel Stotz and Matthias Deeg from German pentesting outfit SySS GmbH, are three: It is deployed worldwide and can be controlled remotely. LOGO! is an intelligent logic module meant for small automation projects in industrial (control of compressors, conveyer belts, door control, etc.), office/commercial and home settings (lighting control, pool-related control tasks, access control, etc.). If the name doesn’t show up in your Virtual Network Editor, select the “Restore Defaults” button and it should show up.LOGO!, a programmable logic controller (PLC) manufactured by Siemens, sports three vulnerabilities that could allow remote attackers to reconfigure the device, access project files, decrypt files, and access passwords.

You can find the details on how to poll data from a Siemens PLC in our documentation. Fore more details, check the Siemens Data Acquisition. supported protocols: MPI, Profibus, ISOTCP. In VMware, Workstation, “VMnet0” is always going to be the bridged connection. The embedded IO server of Ewon allows to poll data out of most of the Siemens PLCs: supported PLC types: S7-1200,S7-1500, S7-300, S7-400, S7-200, S5. The reason you will need to bridge the connection in order to use the discovery protocol is because it is a Layer 2 protocol.

NOTE: You may need to disable firewalls on your VM and PC, depending on any pre-existing security protocols. To establish connection to the PLC, you will first need to verify that your VM connection is bridged to the computer’s network adapter.Īfter bridging the connection, navigate to “Virtual Network Editor” and manually change the settings to bridge the VM to your physical port.

For scenarios where the TIA Portal software platform needs to be installed on a VM, we are able to use a VM to connect to a physical PLC to download, upload, and perform online troubleshooting by following the below process.

To remedy this situation, a Virtual Machine (VM) is an efficient approach that mirrors a computer’s operating system and provides the full functionality of that operating system without the need for additional hardware. 'The holy grail in PLC programmable logic.

Occasionally the situation will arise where a customer will need to support multiple automation platforms that may come in conflict with one another, or software packages that are required to run on different operating systems. Security firm Claroty, which analyzed the vulnerability, says it was able to jailbreak a Siemens product by exploiting the flaw.
