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
Q: Do I have to re-encrypt the protected software?
