Summary
SSA-580125: Multiple Vulnerabilities in SIMATIC eaSie

Notes

Summary
SIMATIC eaSie contains multiple vulnerabilities that could allow an attacker to send arbitrary messages to the underlying message passing framework of the affected system or crash the attached application. Siemens has released an update for the SIMATIC eaSie Core Package and recommends to update to the latest version.
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.
