CVE-2018-9276Paessler PRTG — administrator command injection in the console

The administration console of the network monitoring server (PRTG Network Monitor) before 18.2.39 passes malformed parameters into operating system commands, so an administrator runs code on the server and on the devices it watches.

YOUR NEXT MOVE

Upgrade past 18.2.39 now; exploit code is public, so restrict who holds administrative access to the console and rotate its credentials.
