[Full-disclosure] nVidia.com [Url Redirection flaw]



Yes i've notice that is also vulnerable to Xss.. In fact this link :

http://www.nvidia.com/content/DriverDownload/download_confirmation.asp?kw=&url=%22%3E%3Cscript%3Ealert(%22xss%22)%3C/script%3E

will succefully popup an "xss" alert message. Moreover i've checked
Xssed.com and i saw that a Xss flaw(not url redirection) was already
been found by st@rext ( http://www.xssed.com/mirror/25632/ ) in
17/11/2007. Nevertheless i think that nvidia was not aware of any
vulnerabilities until the day in which I alerted the admin to the url
redirection on nvidia.com (or nvidia is very slow to solve problems,
but i don't wanna do thnik so.. :) ). In fact he answer me that a bug
report was opened and that his team is working to solve the problem.
Despite i've told to nvidia only the "url redirection" flaw i think
that, if "url redirection" will be solved all the xss inherently
vulnerabilites will be solved too.

Well, we have a XSS too, just put whatever you want on the variable
"url" closing first the meta refresh tag, i.e:

http://www.nvidia.com/content/DriverDownload/download_confirmation.asp?kw=&url=";><iframe
src="http://www.yahoo.com/"; with="100%" height=600></iframe><!--

Since nVidia is a trusted site some people could use it to spread
malware directly from there. This is just a simple redirection issue
and nVidia may have to correct this ASAP, even if they are just
"graphics vendors".

Regards.

Hi all, i'm new to the list. I'm an italian student who likes security

Browsing the nVdia web sites, i have found a very basic Url redirection
flaw. Infact when downloading a driver i get Urls like this:


http://www.nvidia.com/content/DriverDownload/download_confirmation.asp?kw=&url=http://us.download.nvidia.com/Windows/179.48/179.48_notebook_winxp_64bit_beta.exe

and connecting to this another Url


http://www.nvidia.com/content/DriverDownload/download_confirmation.asp?kw=&url=http://www.google.it


will redirects succefully to www.google.it! (or other web site of your
choice , or downloadble content..)


Enjoy!
