Objective 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? Body 1.XSS? Xss? What the hell is XSS?

The Crosssite Scripting (cross-site scripting attack) in the OWASP Top 10 security threat allows an attacker to inject malicious script into the Web site through a browser. This vulnerability often occurs in Web applications where user input is required, and if the site has an XSS vulnerability, an attacker could send a malicious script to the user browsing the site, and can also exploit the vulnerability to steal SessionID, which is used to hijack th

In fact, this topic is very early to say, and found that many of the domestic PHP site has XSS loopholes. Today, I happened to see an XSS loophole in PHP5, here to summarize.

way to ensure that the generated pages are encoded correctly is to pass each character in the dynamic content through an encoding function, in which the scripting tags in the dynamic content are substituted for the code in the selected character set. This task is best suited for custom tag libraries.Basics of customizing the tag libraryA custom tag library consists of one or more Java language classes (called tag handlers) and an XML tag library desc
