Does this affect you?

It affects MB connect line mbNET/mbNET.rokey and 3 other products. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

A highly authenticated attacker can alter the config generator injecting a payload into future created configurations. The device is not correctly checking this configuration value before passing it to an system execute leading to code execution. This can result in a total loss of confidentiality, integrity and availability.
