DESCRIPTION:
A weakness has been reported in Moxa EDR-G903 Series, which can be
exploited by malicious people to conduct brute force attacks.

The weakness is caused due to weak entropy used when generating HTTPS
and SSH keys, which can be exploited to brute force the private key
based on the host key and disclose sensitive information via
Man-in-the-Middle (MitM) attacks.

The weakness is reported in firmware versions prior to 2.11.

SOLUTION:
Update to version 2.11.
