## How to fix

- Fixed in NoMachine v10.1.7, v9.9.6, v8.27.1

## Technical details

The vulnerability stems from insufficient entropy in Redis credential generation within NoMachine's authentication mechanism. A local attacker who has already gained low-privilege code execution can exploit weak credentials to access the Redis database and escalate to service account privileges. The flaw allows arbitrary code execution in the context of the NoMachine service, providing a path from low-privilege user to full service compromise.
