In
this following post we will have some basic look over Cross Site
Scripting. Cross site scripting is also known as XSS and many times
people also abbreviate it as CSS (by the way CSS means Cascading Style
Sheets). Commonly XSS is web application attack and not web server attack,
it occurs in web application which accepts input without validation and
sanitization resulting giving an attacker chance to run a malicious
script. XSS vulnerability occurs in a web application due to dynamic
nature of a web page which is attained by Java Scripts, VB Scripts,
ActiveX controls, Flash contents and scripts and sometimes with help of
HTML too.
