Summary
SSA-679335: Multiple Vulnerabilities in Embedded FTP Server of SIMATIC CP Modules
Notes
Summary
SIMATIC CP 1543-1 and CP 1545-1 devices are affected by multiple vulnerabilities in ProFTPD, a third party component, that could allow a remote attacker to access sensitive information and execute arbitrary code.
Siemens has released updates 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.
