Risk evaluation

The 'piControl' kernel module used in the IndustrialPI, prior to version 2.8.0-1, contains multiple vulnerabilities. Successful exploitation of these vulnerabilities can lead to kernel memory corruption and denial of service.

Mitigatiesamenvatting

Update package 'picontrol' to version 2.8.0-1 or higher.

Risk evaluation

The 'Pictory' web config tool, prior to 2.17.0, has a Cross-Site Request Forgery (CSRF) vulnerability, which makes it vulnerable to session takeover. The 'revpipyload' package, prior to version 0.11.1, has a vulnerability in the file management functionality of its XML-RPC interface. This allows an attacker to access or delete arbitrary files that the 'revpipyload' process has access to.

Mitigatiesamenvatting

Risk evaluation

Authentication is not configured by default for the Node-RED server on the Pilz industrial PC IndustrialPI. An unauthenticated remote attacker has full access to the Node-RED server and can run arbitrary operating system commands on the underlying operating system with privileged rights.

Mitigatiesamenvatting

Consult our PDF with remediations which you can find under [www.pilz.com/downloads](https://www.pilz.com/search#currentPage=1&SEARCH=Security%20Advis.%20IndustrialPI%20Remediat.). In order to activate the authentication as described in the PDF, you have to have the Node-RED service enabled via the web application.

Risk evaluation

The Pilz industrial PC IndustrialPI webstatus application is vulnerable to an authentication bypass.

Mitigatiesamenvatting

Update the webstatus package to version 2.4.6 via the 'apt' package manager. Use 'sudo apt update && sudo apt upgrade -y' to pull and install all available updates for the IndustrialPI. To check the version of the webstatus package, use 'dpkg -l | grep revpi-webstatus'.

Risk evaluation

PiCtory, a web application to configure the Pilz industrial PC IndustrialPI, has three vulnerabilities with varying degrees of severity. The first two are of critical severity and can lead to a bypass of authentication and a cross-site-scripting attack. The third vulnerability with medium severity puts PiCtory at a risk of a reflected cross-site-scripting attack.

Mitigatiesamenvatting

Update the PiCtory package to version 2.12 via the 'apt' package manager. Use 'sudo apt update && sudo apt upgrade -y' to pull and install all available updates for the IndustrialPI. To check the version of the pictory package, use 'dpkg -l | grep pictory'.

PASvisu Runtime: Limit network access to legitimate connections by using a firewall or similarmeasures. Restrict administrative access by setting up user authentication properly.

Risk evaluation

Several Pilz products use the 3rd party component "CodeMeter Runtime" from WIBU-SYSTEM AG to manage software licenses. This component is affected by a vulnerability, which may enable an attacker to gain full control over the system running the software product. The vulnerability can be exploited locally or over the network. Update A, 2023-12-05 changed affected version of "Software PASvisu < 1.15.0" to "Software PASvisu < 1.14.1" removed CVE-2023-4701 because it was revoked.

Risk evaluation

Multiple products of PILZ utilise a third-party TCP/IP implementation - the "Niche Ethernet Stack". This TCP/IP stack contains multiple vulnerabilities which are therefore affecting the products listed above.

Mitigatiesamenvatting

It is adviced to use firewalls or similar network security devices to prevent unauthorized network communication to the products affected.

Risk evaluation

A number of Pilz software tools use the Software CodeMeter Runtime application from WIBU-SYSTEMS AG to manage licences. This application contains a number of vulnerabilities, which enable an attacker to change and falsify a licence file, prevent normal operation of Code- Meter (Denial-of-Service) and potentially execute arbitrary code.

Mitigatiesamenvatting

Use the current Version 7.10 of the Software CodeMeter Runtime, available via the manufacturer's website. https://www.wibu.com/de/support/anwendersoftware/anwendersoftware.html Only use the Software CodeMeter Runtime as Client. The software tools named under affected products use the Software CodeMeter Runtime as Client in their default setting. Pilz also recommends using a local firewall to limit unwanted access to the network ser- vices of the device with Software CodeMeter Runtime installed.

Risk evaluation
