AntiSamy测试

AntiSamy为owasp针对xss提供的处理库，可以配置xml策略来决定过滤的内容，比如标签、属性、css等，自定义策略给开发人员使用成本比较高，AntiSamy也提供了几个内置的策略，其安全级别也不同，过滤的内容也不一样，下边是针对自带的策略的测试。

测试代码：

package com.didichuxing.hive.client;

import org.owasp.validator.html.AntiSamy;
import org.owasp.validator.html.CleanResults;
import org.owasp.validator.html.Policy;

public class RichTextXssTest {

    public static void main(String[] args) {

                AntiSamy as = new AntiSamy();
                try{
                    //Policy policy = Policy.getInstance("antisamy-slashdot.xml");
                    Policy policy = Policy.getInstance("antisamy-ebay.xml");

                    CleanResults cr = as.scan("<img src=http://www.qq.com/a.jpg />", policy);
                    System.out.print(cr.getCleanHTML() + "1
");


                    cr = as.scan("<sCript src=http://www.qq.com/a.js />", policy);
                    System.out.print(cr.getCleanHTML() + "2
");

                    cr = as.scan("<img src=http://www.qq.com/a.jpg onclick=alert(1) />", policy);
                    System.out.print(cr.getCleanHTML() + "3
");

                    cr = as.scan("onfinish=javascript:a=alert;a(1)%3E%3C!—", policy);
                    System.out.print(cr.getCleanHTML() + "4
");


                    cr = as.scan("<img src="javascript:alert('XSS')">", policy);
                    System.out.print(cr.getCleanHTML() + "5
");

                    cr = as.scan("<IMG src=JaVaScRiPt:alert('XSS')>", policy);
                    System.out.print(cr.getCleanHTML() + "6
");

                    cr = as.scan("<IMG src=&#x6A&#x61&#x76&#x61&#x73&#x63&#x72&#x69&#x70&#x74&#x3A&#x61&#x6C&#x65&#x72&#x74&#x28&#x27&#x58&#x53&#x53&#x27&#x29>", policy);
                    System.out.print(cr.getCleanHTML() + "7
");

                    cr = as.scan("<STYLE TYPE="text/javascript">alert('XSS');</STYLE>", policy);
                    System.out.print(cr.getCleanHTML() + "8
");

                    cr = as.scan("<A href=http://www.gohttp://www.google.com/ogle.com/>link</A>", policy);
                    System.out.print(cr.getCleanHTML() + "9
");

                    cr = as.scan("<META HTTP-EQUIV="refresh" CONTENT="0;url=javascript:alert('XSS');">", policy);
                    System.out.print(cr.getCleanHTML() + "10
");




                }
                catch(Exception ex) {
                    ex.printStackTrace();
                } ;
            }

}
