Summary
SSA-921449: Plaintext Storage of a Password Vulnerability in LOGO! V8.3 BM Devices

Notes

Summary
LOGO! V8.3 BM (incl. SIPLUS variants) devices contain a plaintext storage of a password vulnerability. This could allow an attacker with phyiscal access to an affected device to extract user-set passwords from an embedded storage IC. Siemens has released new hardware versions with the LOGO! V8.4 BM and the SIPLUS LOGO! V8.4 BM product families for all affected devices in which the vulnerability is fixed. See the chapter "Additional Information" below for more details.
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.
