Software link: http://www.west-cs.com/resources/software-temp-control/pma-products-software/
Application Path: C:Program Files (x86)PMA ToolsBlueControlBlueControl.exe
Affected version: 3.5.SR5

Summary: Engineering Tool for West Pro Series of controllers (KS20-1, KS92-1,

caused due to the application loading libraries (sortserver2003compat.dll,
sxs.dll, cryptsp.dll, rpcrtremote.dll) in an insecure manner. This can be
exploited to load arbitrary libraries by tricking a user into opening a
related application files (.BCD, .BCL, .BCT, .EDW, .E80) located on a remote
WebDAV or SMB share.

Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
Microsoft Windows 7 Professional SP1 (EN)
