CVE-2024-31390 - Soflyy Breakdance Code Injection Vulnerability (versions up to 1.7.1)
A new vulnerability, identified as CVE-2024-31390, has been discovered in the popular Soflyy Breakdance library. This critical issue allows for Code Injection attacks within the library, jeopardizing the security of any application relying on it. In this blog post, we will explore the details of this vulnerability, its potential impact, and the necessary steps to mitigate the risks associated with it.
Vulnerability Details
CVE-2024-31390 has been classified as an Improper Control of Generation of Code ('Code Injection') vulnerability. It affects the Soflyy Breakdance library up to version 1.7.1, which is widely used by developers for handling HTML-to-Markdown conversion.
The vulnerability lies in the improper control of generation of code, which might lead to unexpected execution of malicious code. The attacker could exploit this vulnerability to inject and execute unauthorized code when the application is processing maliciously crafted input.
Exploit Details
To exploit this vulnerability, an attacker could create a specially crafted HTML payload containing the malicious code, and then send it to an application using the vulnerable version of Soflyy Breakdance library. When the application processes the payload, the malicious code will be executed in the context of the running application.
Here is a code snippet demonstrating the vulnerability
const breakdance = require('breakdance');
const html = `
<html>
<body>
<p>This is a test.</p>
<script>console.log('Code Injection!');</script>
</body>
</html>
`;
const markdown = breakdance(html);
console.log(markdown);
In this example, the injected JavaScript code console.log('Code Injection!'); will be executed when processing the HTML string, which should not have happened.

Mitigation
The recommended way to mitigate this vulnerability is to update the Soflyy Breakdance library to version 1.7.2 or later. By doing so, you will ensure that you are using a patched version of the library that no longer contains the vulnerability.
To update, simply run the following command in your project directory
npm install --save breakdance@latest
After the update, you should also test your application with the updated library to make sure nothing breaks, and verify that the Code Injection vulnerability is no longer present.
If for some reason, you are unable to update your dependencies at this time, it is advised to perform proper input sanitization and validation for any untrusted data before passing it to the affected library.
Conclusion
CVE-2024-31390 represents a serious security risk for any application using the vulnerable versions of Soflyy Breakdance library, as it enables attackers to inject and execute unauthorized code. It is essential for developers to respond immediately by updating their dependencies to the latest version, and to implement proper security measures around user-generated input to better protect their applications from similar vulnerabilities in the future.
