Descriptions

In Rockwell Automation FactoryTalk Services Platform, all versions, the redundancy host service (RdcyHost.exe) does not validate supplied identifiers, which could allow an unauthenticated, adjacent attacker to execute remote COM objects with elevated privileges.

En Rockwell Automation FactoryTalk Services Platform, todas las versiones, el servicio de host de redundancia (RdcyHost.exe) no comprueba los identificadores suministrados, lo que podría permitir a un atacante adyacente no autenticado ejecutar objetos COM remotos con privilegios elevados

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Rockwell Automation FactoryTalk View SE. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the AddAgent method. The issue results from a lack of authentication required to instantiate a COM object on the server. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
