Han Lee from Apple Information Security reported these vulnerabilities to Siemens.
Siemens has identified the following workarounds and mitigations users can apply to reduce risk:
- Harden the application’s host to prevent local access by untrusted or unauthorized personnel.
- Limit access to port 4544/tcp to known, trusted IP addresses with a firewall.
As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ operational guidelines for industrial security and following recommendations in the product manuals.
