CVE-2025-48466: Vulnerability in Advantech Advantech Wireless Sensing and Equipment (WISE)
Successful exploitation of the vulnerability could allow an unauthenticated, remote attacker to send Modbus TCP packets to manipulate Digital Outputs, potentially allowing remote control of relay channel which may lead to operational or safety risks.
AI Analysis
Technical Summary
CVE-2025-48466 is a vulnerability identified in Advantech's Wireless Sensing and Equipment (WISE) product, specifically affecting version A2.01 B00. The vulnerability allows an unauthenticated remote attacker to send Modbus TCP packets to the device, enabling manipulation of Digital Outputs. Modbus TCP is a widely used protocol in industrial control systems (ICS) for communication between devices such as sensors, actuators, and controllers. By exploiting this vulnerability, an attacker can remotely control relay channels on the device without requiring authentication or user interaction. This unauthorized control could lead to unintended activation or deactivation of connected equipment, potentially causing operational disruptions or safety hazards. The lack of authentication and the remote nature of the exploit significantly increase the risk, as attackers can leverage network access to the device to manipulate physical processes. Although no known exploits are currently reported in the wild, the vulnerability's characteristics suggest it could be leveraged in targeted attacks against industrial environments that rely on Advantech WISE devices for monitoring and control. The absence of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for immediate mitigation efforts by affected organizations.
Potential Impact
For European organizations, particularly those in industrial sectors such as manufacturing, energy, utilities, and critical infrastructure, this vulnerability poses a significant risk. The ability to remotely manipulate relay channels could disrupt automated processes, leading to production downtime, equipment damage, or safety incidents that endanger personnel. Given the widespread use of Modbus TCP in industrial environments, exploitation could compromise the integrity and availability of operational technology (OT) systems. This may result in financial losses, regulatory penalties, and reputational damage. Additionally, safety risks arising from unintended control of physical devices could have severe consequences, including injury or environmental harm. The vulnerability's unauthenticated nature means that attackers do not need valid credentials, increasing the likelihood of exploitation if network access controls are insufficient. European organizations with network-exposed Advantech WISE devices or inadequate segmentation between IT and OT networks are particularly vulnerable. The threat also aligns with increasing concerns about cyberattacks targeting European critical infrastructure, where disruption of industrial control systems is a strategic objective for some threat actors.
Mitigation Recommendations
1. Network Segmentation: Immediately isolate Advantech WISE devices from public and less trusted networks. Implement strict network segmentation to limit access to these devices only to authorized management systems. 2. Access Control: Deploy firewall rules and access control lists (ACLs) to block unauthorized Modbus TCP traffic from untrusted sources. Only allow Modbus TCP communication from known, secure management stations. 3. Monitoring and Logging: Enable detailed logging of Modbus TCP traffic and monitor for anomalous commands or unexpected relay activations. Use intrusion detection systems (IDS) tailored for industrial protocols to detect potential exploitation attempts. 4. Device Hardening: Review device configurations to disable any unnecessary services or interfaces that could be exploited. If possible, change default network settings to reduce exposure. 5. Vendor Coordination: Engage with Advantech for updates on patches or firmware fixes addressing this vulnerability. Plan for timely deployment of security updates once available. 6. Incident Response Preparedness: Develop and test response procedures for potential exploitation scenarios, including rapid isolation of affected devices and recovery of control systems. 7. Physical Safeguards: Where feasible, implement physical controls or manual overrides for critical relay channels to mitigate risks from remote manipulation. 8. Network Access Controls: Employ VPNs or secure tunnels with strong authentication for remote access to OT devices to prevent unauthorized Modbus TCP traffic.
