Improper file permissions in the default installation of TIA Portal may allow an attacker with local file system access to manipulate resources which may be transferred to devices and executed there by a different user. No special privileges are required, but the victim needs to transfer the manipulated files to a device. Execution is caused on the target device rather than on the PG device.
