Name: XSS All-life: Cross-Site Scripting Why not CSS? Since CSS has been widely used in the field of web design as Cascading Style Sheets, cross is abbreviated as X with similar pronunciation.

(For example, adding an administrator or posting a fraudulent status ).It is a CSRF that has been published by Renren to use the Page code. The CSRF of Renren should not be uncommon. It will happen almost every time you engage in an activity.The figure shows that the CSRF code can be executed on a third-party site, so even if there is an input check,CSRF can be bypassed

-site scripting. It is named XSS to distinguish it from CSS Cascading Style Sheets. It is a security vulnerability attack for website applications and a type of code injection. It allows malicious users to inject code into the webpage, and other users will be affected when they watch the webpage. This type of attacks usually contain HTML and user-side scripting languages. What is CSRF? The full name of CSRF

A couple of years ago I was too red by @ fmavituna's work on XSS Shell and decided to write a new extended version (XSS-Shell-NG) using a PHP and a MySQL backend rather than the ASP/Access combination of the original. I never released the tool publicly, as my main aim of making XSS Shell easier to use was never really accomplished; it still required a significant

ObjectiveThe previous article on the WEB security aspects of the actual combat, mainly to solve the SQL blind security vulnerabilities. This article was supposed to write an article on how to prevent XSS attacks, but to think about it, or decide to first understand the XSS in theory. Next article, then deeply study how to prevent the problem.ConceptWhat exactly is an XS
