Firstly, .vbe is encoded vbscript, so are you sure about what it does?
In addition to the usual security concerns of running encoded scripts, does this need to be run in a user context? Bigfix actions run under the SYSTEM context by default.
If running as the current user is needed see Tip - Action Override User settings for advice.
It is a long, long time since I have done anything with VBScript, but the following should be a good template
action uses wow64 redirection false
override wait
hidden=true
wait "{pathname of file "cscript.exe" of native system folder}" //B //NoLogo "C:\Rizen Network Tool\Push.vbe"
