TITLE

RSLinx OPC Automation ActiveX Control Stack Buffer Overflow Vulnerability

Trust: 1.1

DESCRIPTION

Rockwell Automation RSLinx is a communication management software provided by Rockwell for users. When creating a debug string, the OPC Automation ActiveX control (\"RsiOPCAuto.OPCServer\") has a boundary error, and submitting a long string to the \"ProgID\" parameter of the \"Connect()\" method triggers a stack-based buffer overflow. Successful exploitation of a vulnerability can execute arbitrary code in the context of an application. The RSLinx ActiveX control is prone to a remote stack-based buffer-overflow vulnerability that affects the 'RsiOPCAuto.OPCServer' ActiveX control. Failed exploit attempts will result in a denial-of-service condition. The following products are vulnerable: Rockwell OPC Automation ActiveX Control version 1.1.8.0 RSLinx 2.3.1 Build 10
