Pilz: Multiple products prone to WIBU-SYSTEMS CodeMeter vulnerabilities
Published

Last update

Affected sectors
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.
Mitigation summary
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.
