Affected: GE Proficy HMI/SCADA - CIMPLICITY, GE Proficy Process Systems with CIMPLICITY

The CIMPLICITY Web-based access component, CimWebServer, does not check the location of shell files being loaded into the system. By modifying the source location, an attacker could send shell code to the CimWebServer which would deploy the nefarious files as part of any SCADA project. This could allow the attacker to execute arbitrary code.
