+# kkFileView ZipSlip Remote Code Execution
+
+[中文版本(Chinese version)](README.zh-cn.md)
+
+kkFileView is an open source document online preview solution.
+
+In the version prior to 4.4.0-beta, kkFileView has a ZipSlip issue. Attackers can use this issue to upload arbitrary files to the server and execute code.
+
+References:
+
+- <https://github.com/luelueking/kkFileView-v4.3.0-RCE-POC>
+
+## Vulnerable environment
+
+Execute following command to start a kkFileView 3.4.0:
+
+```
+docker compose up -d
+```
+
+After the server is started, you can see the index page at `http://your-ip:8012`.
+
+## Exploit
+
+First, generate a craft POC by [poc.py](poc.py):
+
+```
+python poc.py
+```
+
+A `test.zip` file will be written.
+
+Upload `test.zip` and the [sample.odt](samople.odt) to the kkFileView server:

+
+Then, click the "preview" button of `test.zip`, the zip file will be listed:
+
+![](2.png)
+
+Finally, click the "preview" button of `sample.odt`.
+
+You can see the `touch /tmp/success` has been executed successful:

+# 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。
+
+参考链接：
+
+- <https://github.com/luelueking/kkFileView-v4.3.0-RCE-POC>
+
+## 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：
+
+![](1.png)
+
+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：
+
+![](2.png)
+
+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：
