In PHOENIX CONTACT PLCnext Engineer version 2020.3.1 and earlier an improper path sanitation vulnerability exists on import of project files.

The build settings of a PLCnext Engineer project (.pcwex) can be manipulated in a way that can result in the execution of remote code. The attacker needs to get access to a PLCnext Engineer project to be able to manipulate files inside. Additionally, the files of the remote code need to be transferred to a location which can be accessed by the PC that runs PLCnext Engineer. When PLCnext Engineer runs a build process of the manipulated project the remote code can be executed.

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.
