Summary
SSA-722410: Multiple Vulnerabilities in User Management Component (UMC)
Notes
Summary
Siemens' User Management Component (UMC) is affected by multiple vulnerabilities that could allow an unauthenticated remote attacker to execute arbitrary code or to cause a denial of service condition.
Siemens has released a new version for User Management Component (UMC) and recommends to update to the latest version. Siemens recommends specific countermeasures for products where fixes 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.
