CVE-2025-41670

Untrusted Search Path

A local user with low privileges may be able to influence the behavior of a privileged system service by manipulating configuration or application-related files located in user-writable areas of the filesystem. The affected service processes data from locations that are not sufficiently protected against modification by low-privileged users. As the service runs with elevated privileges, successful exploitation may result in a local privilege escalation.

CVE-2025-41669

Insufficient Verification of Data Authenticity

The Web-based Management allows a remote low privileged Engineer user to install additional APPs on the device downloaded from the PLCnext Store without implementing any data verification mechanism, leading to the capability for an Engineer user to reach arbitrary code execution with root privileges on the PLC device. A successful exploitation may allow to install a manipulated APP package, potentially impacting integrity and availability of the PLCnext Control.
