CVE-2024-48843 - Denial of Service Vulnerabilities Discovered in ABB ASPECT - Enterprise v3.08.02, NEXUS Series v3.08.02, and MATRIX Series v3.08.02 Products

As technology advances and industries become more reliant on interconnected systems and services, securing these networks and devices is of utmost importance. Recently, a severe vulnerability has been discovered that could potentially lead to the disruption of critical services, affecting several products from ABB, a leading provider of innovative technologies for industries across the globe. The vulnerability, designated as CVE-2024-48843, is a Denial of Service (DoS) that poses a significant risk for affected devices and their users.

Exploit Details

Denial of Service vulnerabilities occur when an attacker floods a target with excessive traffic or requests, rendering the system unable to process legitimate requests, effectively disrupting its operations. In this case, the CVE-2024-48843 vulnerability impacts the following products:

MATRIX Series v3.08.02

This vulnerability, if exploited, can lead to serious implications such as service interruption and potential downtime for organizations relying on these systems.

Code Snippet

The exact method of execution is not disclosed to prevent malicious actors from causing harm; however, a simple example of how a Denial of Service attack could be designed is illustrated below:

import socket

target_ip = "target_device_ip"
target_port = 80
message = "GET / HTTP/1.1\r\nHost: target_device_ip\r\n\r\n" * 100

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

try:
    sock.connect((target_ip, target_port))
    sock.sendall(message.encode("utf-8"))
    response = sock.recv(4096)
    print("Service response:", response)
except Exception as e:
    print("Connection error:", e)
finally:
    sock.close()
