Description

A vulnerability has been identified in SIMOTION C240 (All versions >= V5.4 < V5.5 SP1), SIMOTION C240 PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D410-2 DP (All versions >= V5.4 < V5.5 SP1), SIMOTION D410-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D425-2 DP (All versions >= V5.4 < V5.5 SP1), SIMOTION D425-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D435-2 DP (All versions >= V5.4 < V5.5 SP1), SIMOTION D435-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D445-2 DP/PN (All versions >= V5.4), SIMOTION D445-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D455-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION P320-4 E (All versions >= V5.4), SIMOTION P320-4 S (All versions >= 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.
