Summary

Affected SIPROTEC 5 devices contain a development shell which is accessible via a physical interface which is not properly restricted. This could allow an unauthenticated attacker with physical access to an affected device to execute arbitrary commands on the device.

Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where fixes are not, or not yet available.
