SSA-310038: Multiple Vulnerabilities in SCALANCE X Switch Devices
Notes
Summary
Several SCALANCE X switches contain multiple vulnerabilities. An unauthenticated attacker could reboot, cause denial-of-service conditions and potentially impact the system by other means through heap and buffer overflow vulnerabilities.
Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens is preparing further updates and recommends specific countermeasures for products where updates are not, or not yet available.
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.
