A vulnerability has been identified in SINAMICS G220 V6.4 (All versions < V6.4 HF2), SINAMICS S200 V6.4 (All versions), SINAMICS S210 V6.4 (All versions < V6.4 HF2). The affected devices allow a factory reset to be executed without the required privileges due to improper privilege management as well as manipulation of configuration data because of leaked privileges of previous sessions. This could allow an unauthorized attacker to escalate their privileges.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
