Hi,

Thanks for updating the script Ron.
That's really weird that it was working for me though.

@George, thanks for the hint with the special character "-".

I fixed up the code quite a bit and submitted it on irc, it cleanly
detects vulnerable and patched hosts now.

work
fine.

There are some fixes around already. By fixing the LFI, the HTTP
response status
won't be 200, so the script will not return a false positive.

It works if I switch out the string.match() with "==".

I don't know why, though!

That's because Lua string.match() method expects a pattern as a second
argument
(not a raw string) and the special "-" character is interpreted as the
Lua
modifier for repetitions. Thanks for cathing this.
