Siemens Healthineers published advisory SHSA-741697 on November 17, 2022, covering seven vulnerabilities in the web services of the syngo Dynamics server before version VA40G HF01: CVE-2022-42732, CVE-2022-42733, CVE-2022-42734, CVE-2022-42891, CVE-2022-42892, CVE-2022-42893 and CVE-2022-42894.

The flaws could allow man-in-the-middle attacks, leak NTLM credentials, and let an attacker read and write data on the local file system. Siemens Healthineers released an update and recommends moving to the latest version.

Leaked NTLM credentials are worth more than the server they came from, because they can be replayed against other Windows hosts in the domain. Patch the server and then check the accounts it uses.
