Pilz PNOZmulti Configurator prior to version 10.9 allows an authenticated attacker with local access to the system containing the PNOZmulti Configurator software to view sensitive credential data in clear-text. This sensitive data is applicable to only the PMI m107 diag HMI device. An attacker with access to this sensitive data and physical access to the PMI m107 diag can modify data on the HMI device.
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
