Summary

A vulnerability has been identified in SIMOTION C240, C240 PN, D410-2 DP, D410-2 DP/PN, D425-2 DP, D425-2 DP/PN, D435-2 DP, D435-2 DP/PN, D445-2 DP/PN, D455-2 DP/PN, P320-4 E and P320-4 S (all versions >= V5.4 < V5.5 SP1, and some >= V5.4). When operated with Security Level Low the device does not protect access to certain services relevant for debugging. This could allow an unauthenticated attacker to extract confidential technology object (TO) configuration from the device.

Risk Assessment

An unauthenticated attacker with network access may obtain confidential controller configuration information, potentially facilitating further attacks or disruption of industrial processes. This poses a risk to confidentiality and operational security.

Recommendation

Update SIMOTION software to version V5.5 SP1 or later. If possible, avoid using Security Level Low and restrict network access to the devices.
