Fixes

Solution

Upgrade firmware of affected E3 Supervisory Controls to a version > 2.30F1.


Workaround

Restrict access to the E3 Supervisory Controls network interface (ETH 0) by use of restricted VLAN or subnet and / or network firewall. Ensure the restricted VLAN or subnet is never accessible from untrusted networks.
