Summary
The TRUMPF product versions listed below include a Wibu CodeMeter component that is vulnerable to a privilege escalation vulnerability through the CodeMeter installer on Windows.
Impact
The CodeMeter installer on Windows has a vulnerability that allows under certain circumstances an Escalation of Privileges for an unprivileged account. After installation on an unprivileged account with UAC using the built-in administrator account, CodeMeter launches the CodeMeter Control Center with system privileges.

Vulnerabilities
Expand / Collapse allWibu CodeMeter before 8.30a sometimes allows privilege escalation immediately after installation (before a logoff or reboot). For exploitation, there must have been an unprivileged installation with UAC, and the CodeMeter Control Center component must be installed, and the CodeMeter Control Center component must not have been restarted. In this scenario, the local user can navigate from Import License to a privileged instance of Windows Explorer.
Remediation
New versions are available for the affected products. These include an updated WiBu CodeMeter (bundled with TRUMPF License Expert). If your installation is affected, the easiest fix is to install the latest TRUMPF License Expert from www.trumpf.com/en_INT/products/softwa....
