CVE-2024-23739 - Remote Code Execution Vulnerability in Discord for macOS Version ..291 and Earlier

As the world becomes more interconnected, technologies such as Discord have allowed people to communicate and collaborate with ease. With the increase in popularity of such technologies, it is also important to pay close attention to their security. This post will discuss a critical vulnerability, designated as CVE-2024-23739, that affects Discord for macOS version ..291 and earlier. The vulnerability allows remote attackers to execute arbitrary code via the RunAsNode and enableNodeCliInspectArguments settings.

Vulnerability Details

Discord for macOS versions ..291 and earlier suffer from a remote code execution vulnerability that primarily affects the RunAsNode and enableNodeCliInspectArguments settings. Remote attackers can successfully exploit this vulnerability and execute arbitrary code on the target user's system. The exploit requires no user interaction, which makes it quite dangerous.

Exploit Walkthrough

In order to exploit this vulnerability, an attacker would need to create a malicious payload and then send it to the target Discord user. The payload would be specifically crafted to include malicious JavaScript code that takes advantage of the RunAsNode and enableNodeCliInspectArguments settings. The following is a simplified example of a malicious payload code snippet:

// Sample Malicious Payload Code Snippet
const { spawn } = require('child_process');
const arbitraryCommand = 'touch /tmp/exploit_was_here';

const exploit = spawn('bash', ['-c', arbitraryCommand], {
  detached: true,
  stdio: 'ignore',
});

exploit.unref();

By sending this malicious payload to a Discord for macOS user with version ..291 and earlier, an attacker can execute the arbitrary command (in this example, touch /tmp/exploit_was_here) on the target user's system.
