# kkFileView ZipSlip 远程命令执行漏洞
|
||||
|
||||
kkFileView是一个文档预览解决方案。
|
||||
|
||||
在kkFileView 4.4.0-beta以前,存在一处ZipSlip漏洞。攻击者可以利用该漏洞,向服务器任意目录下写入文件,导致任意命令执行漏洞。
|
||||
|
||||

|
||||
|
||||
## 漏洞环境
|
||||
|
||||
执行如下命令启动一个kkFileView 3.4.0服务器:
|
||||
|
||||
```
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
服务启动后,访问`http://your-ip:8012`即可查看到首页。
|
||||
|
||||
## 漏洞复现
|
||||
|
||||
首先,修改并执行[poc.py](poc.py),生成POC文件:
|
||||
|
||||
```
|
||||
python poc.py
|
||||
```
|
||||
|
||||
然后,`test.zip`将被写入到当前目录下。
|
||||
|
||||
上传`test.zip`和[sample.odt](sample.odt)两个文件到kkFileView服务中:
|
||||
|
||||

|
||||
|
||||
然后,点击`test.zip`的“预览”按钮,可以看到zip压缩包中的文件列表:
|
||||
|
||||

|
||||
|
||||
最后,点击`sample.odt`的“预览”按钮,触发代码执行漏洞。
|
||||
|
||||
可见,`touch /tmp/success`已经成功被执行:
