Multiple buffer overflows in CimWebServer.exe in the WebView component in GE Intelligent Platforms Proficy HMI/SCADA - CIMPLICITY before 8.0 SIM 27, 8.1 before SIM 25, and 8.2 before SIM 19, and Proficy Process Systems with CIMPLICITY, allow remote attackers to execute arbitrary code via crafted data in packets to TCP port 10212, aka ZDI-CAN-1621 and ZDI-CAN-1624.
The (1) CimView and (2) CimEdit components in GE Proficy HMI/SCADA-CIMPLICITY 8.2 and earlier allow remote attackers to gain privileges via a crafted CIMPLICITY screen (aka .CIM) file.
Directory traversal vulnerability in substitute.bcl in the WebView CimWeb subsystem in GE Intelligent Platforms Proficy HMI/SCADA - CIMPLICITY 4.01 through 8.0, and Proficy Process Systems with CIMPLICITY, allows remote attackers to read arbitrary files via a crafted packet.
The affected product is vulnerable due to cleartext transmission of credentials seen in the CIMPLICITY network, which can be easily spoofed and used to log in to make operational changes to the system.
