Re: How does Google get confidential URL-strings?

I don't think this was the case. By the time I found out that the
URLs, which were indexed by Google were never used by the affected
users. They were just part of the website. This leads me to the
conclusion that Typo3 may have exposed these URLs over its rendered
HTML pages. So to me, it looks like a Typo3 bug, which is not any more
reconstructable...

Thanks

Hello guys

I was recently confronted with the problem, where using Google-Hacking
techniques I was able to find entries that point to my employer’s
website while having confidential username and password parameters in
the URL. Using this URL listed as Google’s search result everyone
could access personalized accounts on this website.

I see two kinds of problems here.

First, the web application should not put confidential parameters into
the URL. This is the GET/POST discussion which is clear to me.

Second, even if a web application puts these parameters into the URL I
wonder how his URL gets indexed by Google. Does anyone have a clue how
this can happen?

Interestingly Google lists only three user accounts while the website
has about 10’000 registered users. I was thinking about two
possibilities:
- The web applicaiton somehow leaks this URL to the Google search spider
- The affected users somehow publish their browser history on the web
(probably though malware?)

It would be interested if someone has Ideas on how the second problem
can be explained.

By the way, the Google query, that lead to the problematic entries
looked as follows: site:mydomain.com inurl:password inurl:user.

Any ideas?

Regards
Joe
