Illustration: How XSS attacks work Currently, of the top 1000 most popular websites with access traffic, 6% have become victims of XSS attacks. Since the birth of modern Web development technology, cross-site scripting attacks and Web-based security vulnerabilities have been around us, that is, the XSS attacks we will introduce to you.

During front-end WEB development, many developers often leave XSS vulnerabilities due to a large number of URLs and multiple transmission parameters. Once a vulnerability is detected in the security test, defect must be enabled for the developer. Defect has a very high priority and must be resolved immediately. Developers often use tricky methods to quickly block current vulnerabilities. As a result, this vulnerability is often blocked, and the vulner

Example: SQL injection attack XSS attacks Copy Code code as follows: Arbitrary code Execution file contains and CSRF. } There are a lot of articles about SQL attacks and all kinds of anti injection scripts, but none of this solves the underlying problem of SQL injection See Code: Copy Code code as follows: mysql_connect ("localhost", "root", "123456") or Die ("D

An XSS attack is an attack by which an attacker injects JavaScript code into a user's running page. To avoid this attack, some apps try to remove the JavaScript code from user input, but it's hard to fully implement. In this article, you will first show some code that attempts to filter JavaScript, and then give it a way to bypass it.Take an online store application Magento Filter class Mage_core_model_input_filter_maliciouscode as an
