This module exploits a stack based buffer overflow in Yokogawa CENTUM CS 3000 by using its BKHOdeq.exe service. The BKHOdeq.exe service, started when running the FCS / Test Function listens by default on TCP/20109, TCP/20171 and UDP/1240. By sending a specially crafted packet to the port TCP/20171 its possible to trigger a stack based buffer overflow which allows execution of arbitrary code with the privileges of the CENTUM user.
This module exploits a stack based buffer overflow in Yokogawa CENTUM CS 3000 by using its BKBCopyD.exe service. The Yokogawa Centum CS3000 solution uses different services in order to provide all its functionality. The BKBCopyD.exe service, started when running the FCS / Test Function, listens by default on TCP/20111. By sending a specially crafted packet to the port TCP/20111, it it is possible to trigger a stack based buffer overflow which allows execution of arbitrary code with the privileges of the CENTUM user.
