Have Nicolas tested his change before mailing pen-test?
If you change Ian Vitek's briiis with the NEW LINE, the double encoding vulnerability testing (%255c)
will fail due to the last '../'.

I, of course, tested it before sending the patch ... and it works fine
for me.
Here an Ethereal capture (done with "./briiis.pl -s XXXXXX -v -F
%255c"):

Briiis is not a toy, it is a weapon. Use it to defend yourself, not attacking. ;-)

No, briiis.pl is a tool. Just a tool. Like guns.
And policemen and robbers both have guns ...
