Behobenwago_psirt
The I/O-Check service protocol is only needed during installation and commissioning, not during normal operations. It is highly recommended to disable the I/O-Check service after commissioning. This is the easiest and securest way to protect your device from the listed vulnerabilities. Regardless of the action described above, the vulnerabilities are expected to be fixed in FW16 Release in Q2/2020.
Mitigationwago_psirt
* Disable I/O-Check service. * Restrict network access to the device. * Do not directly connect the device to the internet. * Disable unused TCP/UDP-ports.
