什么是XSS?XSS又叫CSS (Cross Site Script) ,跨站脚本攻击.它指的是恶意攻击者往Web页面里插入恶意html代码,当用户浏览该页之时,嵌入其中Web里面的html代码会被执行,从而达到恶意用户的特殊目的.XSS属于被动式的攻击,因为其被动且不好利用,所以许多人常呼略其危害性.

跨站攻击有多种方式,由HTML语言允许使用脚本进行简单交互,入侵者便通过技术手段在某个页面里插入一个恶意HTML代码——例如记录论坛保存的用户信息(Cookie),由于Cookie保存了完整的用户名和密码资料,用户就会遭受安全损失.当然,攻击者有时也会在网页中加入一些以.JS 或.VBS为后尾名的代码时,在我们浏览时,同样我们也会被攻击到.

2 }1 G; W% N! t2:严格控制输入类型,根据实际需求选用数字,字符,特殊格式的限制.. k [7 @# b3 D h5 y2 ]
3:在浏览器端输出时对HTML特殊字符进行了转义,常见采用htmlspecialchars,htmlentities.但是过滤了特殊字符,并不意味就是安全的.很多绕过方法都是争对单纯过滤进行的,譬如URL,8进制,16进制,String.fromCharCode转编码,UBB绕过等.因此应注意每处接受动态输入的代码审计.数据保存在innertxt,标签属性均应处于“”内.

复制代码通过以上几个蠕虫,我们可以总结蠕虫的工作原理为:2 _- o8 o3 c# |1 K+ o
1:首先写入调用蠕虫代码到一个存在XSS漏洞的位置(在非长久性XSS漏洞里,我们也可以通过把短暂性的XSS连接通过各种传播方式,发送给其他用户,当某个用户中了XSS后,再通过蠕虫,向其好友发送同一短暂性XSS连接.)
1 o% w% p3 u6 O: w, @) V3 k3 d0 Z* a% r
2:受害用户在登陆状态中,观看了存在XSS的问题页面,JS执行,并植入XSS蠕虫代码到该用户帐户中,且通过搜索好友等方法,传播给其他用户.即复制感染过程.(在论坛或者回复类型页面中传播XSS蠕虫,只要保证每页面同时存在2个或者以上蠕虫,就可以保证蠕虫不会被增加的数据覆盖.)/ L3 w0 Y; N X) g, C$ c
. P7 i6 s7 q6 U4 a& J9 ~. L
综上所述,结合以上种种技巧,就可以创造我们自己的XSS蠕虫了.在我们的蠕虫里,我们可以添加截取屏幕功能,DDOS功能,可以判断客户端浏览器的版本,读取并且发送客户端的本地文件~
