XSS漏洞模糊檢測(cè)系統(tǒng)的開(kāi)發(fā)與結(jié)果研究XSS漏洞模糊檢測(cè)系統(tǒng)的開(kāi)發(fā)與結(jié)果研究
摘要:XSS漏洞是Web應(yīng)用程序中十分常見(jiàn)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(kāi)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(lèi),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(huà)的XSS漏洞檢測(cè)方法,該方法考慮了常見(jiàn)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(wèn)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。
