-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of GE Proficy iFix HMI/SCADA. Authentication is
not required to exploit this vulnerability.

The specific flaw exists within the ihDataArchiver.exe process which
listens by default on TCP port 14000. The code within this module trusts
a value supplied over the network and uses it as a length when copying
user-supplied data to a stack buffer. By providing a large enough value,
this buffer can be overflowed leading to arbitrary code execution under
the context of the user running the service.

-- Vendor Response:

GE has issued an update to correct this vulnerability. More details can
be found at:
