# Under Development
There is nothing obvious on the website so let's check the Source:
```html
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Web App Home Page</title>
</head>
<body>
<div> This web app is still under development. </div>
</body>
</html>
```
A comment about cookies? Let's inspect the cookie:
So we have a session cookie:
```
dXNlcg%3D%3D
```
The `%3D` is url encoded for `=` so this already looks a lot like base64, let's decode it and check.
So it says user. Let's change that to something more privileged like `admin`. Base64 encode `admin` and just insert in into your session cookie.
Refreshing the site now displays the flag:
```
SHELL{0NLY_0R30_8e1a91a632ecaf2dd6026c943eb3ed1e}
```
