CVE-2022-38466

Local administrator escalation via writable installed executables

Published Sep 13, 2022 · Updated Aug 3, 2024

Improper access control in Siemens CoreShield One-Way Gateway Software before 2.2 allows local users to gain administrator privileges. The default Windows installation grants local users modify and write permissions on installed executables, enabling replacement with attacker-controlled code. A low-privileged Windows account is required; Siemens has not identified the affected executables or the privileged process that launches them.
