Circutor PowerStudio SCADA 4.0.5 Unquoted Service Path Elevation Of Privilege

Title: Circutor PowerStudio SCADA 4.0.5 Unquoted Service Path Elevation Of Privilege
Advisory ID: ZSL-2015-5281
Type: Local
Impact: Privilege Escalation
Risk: (2/5)
Release Date: 05.12.2015
CIRCUTOR's Electrical Energy Efficiency software (e3) is currently called PowerStudio and encompasses all of the tools needed to manage your power control equipment: from electricity, gas and water meters to reactive energy compensation systems and powerful power analyzers.
The application suffers from an unquoted search path issue impacting the services 'CircutorPowerStudioScadaServer' and 'CircutorPowerStudioServer' for Windows deployed as part of PowerStudio Series. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user’s code would execute with the elevated privileges of the application.
Affected Version
