XSS漏洞模糊检测系统的开发与结果研究XSS漏洞模糊检测系统的开发与结果研究

摘要：XSS漏洞是Web应用程序中十分常见的一种安全漏洞，容易导致用户的个人信息遭到盗取、篡改或者其他不良后果。本文开发了一种XSS漏洞模糊检测系统，并对其进行了实验研究。具体而言，本文首先介绍了XSS漏洞的基本概念和分类，然后结合实际案例，分析了XSS漏洞发生的原理以及影响，接着提出了一种基于字符定位和HTML标签刻画的XSS漏洞检测方法，该方法考虑了常见的XSS攻击向量，如Script、IFrame等，在保证漏洞检出率的同时，具有较高的准确率和鲁棒性，避免了误报漏报的问题。最后，我们在自己搭建的Web应用中进行了实验，结果表明，所提出的XSS漏洞模糊检测系统具有较好的检测性能和可行性。
