摘要：XSS漏洞是Web應(yīng)用程序中十分常見的一種安全漏洞，容易導(dǎo)致用戶的個(gè)人信息遭到盜取、篡改或者其他不良后果。本文開發(fā)了一種XSS漏洞模糊檢測(cè)系統(tǒng)，并對(duì)其進(jìn)行了實(shí)驗(yàn)研究。具體而言，本文首先介紹了XSS漏洞的基本概念和分類，然后結(jié)合實(shí)際案例，分析了XSS漏洞發(fā)生的原理以及影響，接著提出了一種基于字符定位和HTML標(biāo)簽刻畫的XSS漏洞檢測(cè)方法，該方法考慮了常見的XSS攻擊向量，如Script、IFrame等，在保證漏洞檢出率的同時(shí)，具有較高的準(zhǔn)確率和魯棒性，避免了誤報(bào)漏報(bào)的問題。最后，我們?cè)谧约捍罱ǖ腤eb應(yīng)用中進(jìn)行了實(shí)驗(yàn)，結(jié)果表明，所提出的XSS漏洞模糊檢測(cè)系統(tǒng)具有較好的檢測(cè)性能和可行性。
