[Full-disclosure] xss problems

Hi All,
 The following sites have XSS problems

1)  http://chennaionline.com/search/  ( the first search box ) 

The user input for search is later displayed in the result page. No
filtering is done to remove Java Scripts in the query. 


2) http://www.sdbj.com/forgot.asp  

        user is a valid field in the table where email is stored. 

3) http://www.visionoss.com/login/forgotpassword/

     userEmail is a valid field in the table where email is stored. 

I had reported my findings. I am just trying to learn the basics of XSS.
I have few doubts. The site 

http://www.xdisclose.com/tools/yahoocookiepoc.html is capable of
decrypting yahoo cookies. I fail to understand how they decrypt the user
name, dob and country details from cookie.

The relavent cookie contents are 

Y=v=1&n=3nkia0lkek00v
l=h4fb820j4c08b/o
p=m2kvvin013000000
jb=16|47|
iz=600042
r=ak
lg=us
intl=us
np=1


l stands for username, 
p stands for country, year of birth, gender 


Can someone tell me how xdisclose.com tools decrypt username, country,
year of birth and other details.
