RE: privelege escalation with .bat files

["Ben Greenberg" <bengreenb () hotmail com>]

One quick comment.  My problem was that I couldn't execute the bat files, 
and was looking to see if I could post to them(i finally found a seperate 
solution).  My suggestion to anyone who CAN execute bat files is the 
following, even simpler solution, to getting a command prompt:

copy C:/windows/system32/cmd.exe C:/inetpub/scripts/

> From there, you can post commands to cmd.exe through the method explained in 
the paper "One way web hacking".

Peace,

Urthogie
