Solution:
Strictly filter parameters
You can insert a 140-word code! You only need to change the case sensitivity of the tag to bypass detection!The first connection address in the code will be changed! If you write two messages, you can also achieve the effect!The vulnerability page exists on the personal homepage of the hacker! On the personal homepage, you can insert a 140-word code! However, the detection is very strict. There is a status in the sidebar of the home page that can make comments like anything you just talk about!T

We often say that network security should actually include the following three aspects of security: 1. confidentiality, such as user privacy theft and account theft. The common method is Trojan. 2. Integrity, for example, data integrity.

This means that once your website has an xss vulnerability, You can execute arbitrary js Code, the most terrible thing is that attackers can use JavaScript to obtain cookies or session hijacking.

~ Introduction
In this article I will explain all about XSS and more about it. Through this document, I hope to give you an idea of what XSS is, why XSS is used, and how to use
XSS attacks, the full name of cross site scripting attacks (Scripting), are abbreviated as XSS, primarily to differentiate from cascading style sheets (cascading stylesheets,css) to avoid confusion. XSS is a computer security vulnerability that often appears in web applications, allowing malicious Web users to embed code into pages that are available to other use
An XSS attack is a malicious attacker who inserts malicious HTML code into a Web page, and when a user browses to the page, the HTML code embedded inside the Web is executed to achieve the special purpose of the malicious user.
In general, the use of Cross-site scripting attacks allows attackers to steal session cookies, thereby stealing web site users ' privacy, including passwords.
The techniques used by XSS
Create a plug-in II that automatically detects whether XSS exists on the page
Preface:The changes in this version are a little larger than those in the previous version. First, the entire code architecture is modified, which is more intuitive and easy to modify and locate. In addition, in this version, I fixed two bugs in the previous version (which will be mentioned later) and added the pseudo static detection XS

Web attack and Prevention 1, XSS attackCross Site scripting attacks (Scripting) because shorthand CSS, which is ambiguous with cascading style sheets (cascading style Sheets), is named XSSPrinciple: Embed malicious script in Web pages, execute in client browser (such as user input data converted to code execution)Prevention: input data HTML escape processing
statements. of course, an error will also be prompted.
At that time, we found that all information in the current table can be queried after the SQL statement can be executed. for example, the correct administrator account and password are used for logon intrusion ..
Solution 1:
Use javascript scripts to filter out special characters (not recommended, and the indicator is not cured)
If javascript is disabled, attackers can still launch SQL injection attacks ..
Solution 2:
Use the built-in funct

Hello everybody, good man is me, I am a good man, I am -0nise. We often see XSS vulnerabilities in each of the major vulnerability reporting platforms. So the question is, why is there such a loophole? How should this vulnerability be fixed?
