Remote Code Execution Vulnerability in Modbus TCP Communication for Industrial Automation Systems

CVE-2025-48466

What is CVE-2025-48466?

CVE-2025-48466 is a critical vulnerability found in Modbus TCP communication used in industrial automation systems, specifically attributed to Advantech's products. This vulnerability allows an unauthenticated remote attacker to send specially crafted Modbus TCP packets. By exploiting this flaw, attackers can manipulate Digital Outputs, potentially gaining unauthorized control over relay channels used in various industrial applications. Such manipulation could lead to severe operational disruptions and safety hazards, given the critical roles these systems play in controlling industrial processes and machinery.

Potential impact of CVE-2025-48466

1. Operational Disruption: Exploitation of this vulnerability can lead to unauthorized manipulation of industrial equipment, causing operational downtime or failure, which can severely impact production schedules and operational efficiency.

2. Safety Risks: Given the nature of industrial automation systems, unauthorized control over relay outputs could compromise safety protocols, potentially leading to catastrophic failures, injuries, or damage to infrastructure.

3. Remote Access Threats: Since the vulnerability allows for unauthenticated access, it increases the risk of attackers gaining a foothold in critical infrastructures, which may facilitate further exploit attempts or allow for lateral movement within networks.
