Hi

I was trying to run a WScript.Shell command on the server so that i can zip the files in a folder. But to test it out i was trying to just do a simple command

<%
  set wshell = server.createobject("wscript.shell")
 intReturn =  wshell.run ("cmd.exe dir *.* > c:\test.txt")
 Response.Write(intReturn) ' This returns 0
 set wshell = nothing
%>

I have set the permissions of the web folder to Read/Write and also Script Access/Executables

I don't see a question or problem here.  The 0 indicates it executed successfully.  Also, the IUSR_ is going to need to have write access on the file C:\Test.txt.

What were you expecting?

Try this:
     <%
          Dim wshell, proc
          set wshell = server.createobject("wscript.shell")
          set proc = wshell.exec("%comspec% /c dir *.*")

          ' Wait the process to finish
          Do While proc.Status = 0
               WScript.Sleep 100
          Loop

          Response.Write proc.StdOut.ReadAll
          set wshell = nothing
     %>

Hope That Helps,
Dex*

Dex,

Your code is giving me the following error

Object doesn't support this property or method: 'exec'

Also in my code i dont see the test.txt file physically.

IUSR also has the permission

That's really odd.  It should support that method.  Maybe you're using an older version of it?

Try this:
     <%
          Dim wshell, intReturn
          set wshell = server.createobject("wscript.shell")
          intReturn = wshell.run("%comspec% /c dir *.* > c:\test.txt", 0, True)
          Response.Write( intReturn )
          set wshell = nothing
     %>

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

     Your Line:   intReturn = wshell.run ("cmd.exe dir *.* > c:\test.txt")
     Mine Line:   intReturn = wshell.run ("%comspec% /c dir *.* > c:\test.txt", 0, True)

1) In mine, I use the environmental COMSPEC, which will contain the full path to the CMD.EXE.  Like C:\Winnt\system32\cmd.exe ... It might not work because it can't find cmd.exe.

2) I also added the /c, which tells CMD to run the command, and then exit.  Without it, you might end up with a bunch of cmd.exe running on your server with no way to kill them.

3) I also set the last parameter to Run to be "True", which tells it to wait until the program exits before continuning.  That way, if there is a delay creating that file, you won't miss it.

HTH,
Dex*

Hi, in javascript I'm using WScript.Shell, but the line var ws = new ActiveXObject("WScript.Shell"); cause a warning message asking to accept or not the ActiveX interaction. Is there a wau to avoid this message?
Thanx in advance,

The user must set internet secury preferences to allow scripting on activeX control nor marked as "safe"

The easy way to solve this is including your web site in the "safe zone", and relax the security restrictions on that zone


Another tip, the run method is available from JScript 5.6, and Win2K comes by default with JScript 5.5. So if you want the run method works, you must either update the browser to IE6 or the JScript runtime standalone.
