  *YAHOO MAIL XSS BUG*

A XSS bug was identified in YAHOO mail. We are not able to verify whether i=
t
is remotely exploitable, thus we will call it a bug.

Yahoo mail has a *Yahoo Notepad* feature. The same has options for
maintaining folder(s). There exists an option to rename a folder. The promp=
t
which appears allows any arbitrary script execution. However, we are still
not able to verify if it is remotely exploitable.
Screen shot can be seen at the following links

1. https://www.nii.co.in/vuln/yahoo1.jpg
2. https://www.nii.co.in/vuln/yahoo2.jpg

---------------------------------------------------------------------
*
Yahoo mail URL injection/URL redirection:-*

https://login.yahoo.com/config/login?.intl=3Dus&.src=3Dym&.done=3Dhttp%3a//g=
oogle.com


The done parameter is not properly sanitized before returning the URL. Thus
after successful validation the victim will be redirected to any URL (googl=
e
here). This can then be followed by a phishing attack.

---------------------------------------------------------------------

*Yahoo Videos URL Injection/URL Redirection:-*


https://video.search.yahoo.com/video/view?&h=3D92&w=3D120&type=3Drealmedia&r=
url=3Dwww.cricketfundas.com%2Fmultimedia.htm&vurl=3Dwww.nii.co.in/index.htm=
l&back=3Dp%3Dsachin%2Btendulkar%26ei%3DUTF-8%26fl%3D0%26cv%3Dg%26fr%3D%26b%=

=3D22&tt=3D24&p=3Dsachin+tendulkar&dur=3D273


Note that the Play video can be made to point to any URL
(www.nii.co.inhere).This can be done to other parameters as well.

--------------------------------------------------------------------
*Yahoo Multiple URL Redirection:-*
eg. https://in.rd.yahoo.com//prop/?https://google.com<https://in.rd.yahoo.com/=
prop/?https://google.com>
