Descriptions

An unauthenticated remote attacker can send data to RsvcHost.exe listening on TCP port 5241 to add entries in the FactoryTalk Diagnostics event log. The attacker can specify long fields in the log entry, which can cause an unhandled exception in wcscpy_s() if a local user opens FactoryTalk Diagnostics Viewer (FTDiagViewer.exe) to view the log entry. Observed in FactoryTalk Diagnostics 6.11. All versions of FactoryTalk Diagnostics are affected.

Un atacante remoto no autenticado puede enviar datos al archivo RsvcHost.exe escuchando en el puerto TCP 5241 para agregar entradas en el registro de evento de FactoryTalk Diagnostics. El atacante puede especificar campos largos en la entrada del registro, lo que puede causar una excepción no controlada en la función wcscpy_s() si un usuario local abre FactoryTalk Diagnostics Viewer (FTDiagViewer.exe) para visualizar la entrada del registro. Observado en FactoryTalk Diagnostics versión 6.11. Todas las versiones de FactoryTalk Diagnostics están afectadas
