Summary
SSA-550198: Authenticated Remote Code Execution in WinCC
Notes
Summary: Multiple SIMATIC WinCC versions are affected by a database privilege escalation vulnerability that could allow an authenticated user with access to the database to execute commands on the underlying host system. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fixes and recommends mitigations 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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
Additional Resources: For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories
Terms of Use: The use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use.

The affected application does not sufficiently restrict the permissions assigned to a database role. This could allow an authenticated remote attacker with database access to escalate privileges and execute arbitrary commands on the host system where SIMATIC WinCC is installed, potentially leading to a compromise of the system.
