'External Control of File Name or Path' security flaw

I have a c# console application where in I need to write some data from database to a flat file. There output file path and the file name are configurable. I did like below:

using (TextWriter tw = new StreamWriter(strWorkingOutputFile, false))

which is giving following error:

`'External Control of File Name or Path' security flaw.`

Basically, wherever we are giving a configurable path it's throwing that flaw. Any idea on how to resolve this?

Thanks so much in advance.
