Coldfusion CFIDE bitcoin mining exploit?

Just found the following 2 new directories on multiple windows server 2003 installations of coldfusion 9:

{wwwroot}/CFIDE/m32 3/13/2014



{wwwroot}/CFIDE/m64 3/17/2014


When running m32.exe it appears that it’s some type of wrapper for a bitcoin mining operation:
