Descriptions

In Rockwell Automation all versions of FactoryTalk Diagnostics software, a subsystem of the FactoryTalk Services Platform, FactoryTalk Diagnostics exposes a .NET Remoting endpoint via RNADiagnosticsSrv.exe at TCPtcp/8082, which can insecurely deserialize untrusted data.

En Rockwell Automation, todas las versiones del software FactoryTalk Diagnostics, un subsistema de la FactoryTalk Services Platform, FactoryTalk Diagnostics expone un endpoint .NET Remoting por medio del archivo RNADiagnosticsSrv.exe en TCPtcp/8082, lo cual puede deserializar de forma no segura los datos no confiables.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Rockwell Automation ThinManager. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the RNADiagnosticsSrv endpoint, which listens on TCP port 8082 by default. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code under the context of SYSTEM.
