New Web Application Attack - Insecure Indexing
An anonymous reader writes "Take a look at 'The Insecure Indexing Vulnerability - Attacks Against Local Search Engines'
by Amit Klein. This is a new article about 'insecure indexing.' It's a good read -- shows you how to find 'invisible files' on a web server and moreover, how to see contents of files you'd usually get a 401/403 response for, using a locally installed search engine that indexes files (not URLs)."
the department-of-the-bleedingly-obvious...
Even though here's about internal indexing, it reminded me of the old fashion google indexing: Search google with some sensitive terms such as : 'index of /' *.pdf *.ps
I read the article and it seems to be like a good chunk of todays security papers, 'heres a long drawn out explanation of the obvious', I suppose it wasn't as long as it could be, but really ... using a search engine to find a list of files on a website? I suppose someone has to document it..
I mean, I understand its a little more complex as described in the article- but i would hardly call this a 'new web application attack', at best perhaps one of those humorous advisories where the author overstates things and creates much ado about nothing- or at least thats my take;
-1 not profound
My company specialises in search engine technology (for almost a decade now). I've worked quite in-depth with all the big boys (Verity, Autonomy, FAST, ...) and many of the smaller players too (Ultraseek, ISYS, Blue Angel, ...)
I can't recall the last time this kind of attack wasn't mentioned in the documentation for the product, along with instructions on how to disable it. If you choose to ignore the product documentation, you get what you deserve.
It's quite simple folks. Don't open the search engine. ACL query connections. Sanitize queries like you (should?) do other CGI applications. Authenticate queries and results. If you can't be bothered, hire someone who can.

I guess a lot of people have seen this site before, but http://johnny.ihackstuff.com/index.php?module=prod reviews
has a lot of these google exploits etc, he is posting them up so people can check if their sites are secure. There are some interesting presentations by him on the main site about how search engines can be exploited.
Please put this new undocumented tag on your robots.txt file: "hackthis=false" "xss=false" "scriptkiddies=log,drop" And all you problems will be solved.
