Frequently Asked Questions (Q&A)

Q: How critical is the situation in practice?

A: In order to exploit the vulnerability, attackers must have access either to the system itself or to a system on the same network. Attackers must have already broken into or gained access to the network. If they have managed to do so, they can exploit the vulnerability.

Q: Do I have to install the update on all systems?

A: CodeMeter Runtime is affected on all platforms (Windows, macOS, Linux).

Q: My systems are running in a protected environment. Do I still have to install the update?

A: If you can make sure that attackers cannot gain access to your network, then the vulnerability cannot be exploited and an update is not mandatory.

Additional Frequently Asked Questions (Q&A) for software vendors who use CodeMeter for licensing
