Summary
SSA-792319: Missing Read Out Protection in SENTRON 7KM PAC3x20 Devices

Notes

Summary
The read out protection of the internal flash of affected devices was not properly set at the end of the manufacturing process. An attacker with physical access to the device could read out the data. Siemens has released new versions for the affected products and recommends to update to the latest versions.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
