Schneider Electric is establishing a remediation plan for all future versions
of the following models of the Easergy MiCOM P30:
P437
P532
P631
P634
P436
P438
P638
Future versions will include a fix for this vulnerability. We will update this
document when the remediation is available.
Until then, customers should immediately apply the following mitigations to
reduce the risk of exploit:
• Ensure P30 operates within a physically or logically segmented
internal network. Access to this network should be tightly controlled
using standard security mechanisms such as firewalls, intrusion
detection systems (IDS), and other relevant protective measures.
• Reduce the “Minimum inactivity period” using the CAE tool to
shorten session timeout durations and minimize the risk of
unauthorized access due to inactive sessions
Schneider Electric is establishing a remediation plan for a future version of
the Easergy MiCOM P40 Series model numbers with Protocol Option bit as
G, H or L.
