An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
