CVE-2023-51571 in ViewPower Pro
Summary
by MITRE • 04/02/2024
Voltronic Power ViewPower Pro SocketService Missing Authentication Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Voltronic Power ViewPower Pro. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the SocketService module, which listens on UDP port 41222 by default. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-21162.

The vulnerability identified as CVE-2023-51571 represents a critical security flaw in Voltronic Power ViewPower Pro software that exposes systems to unauthorized denial-of-service attacks. This weakness specifically affects the SocketService component that operates on UDP port 41222, creating an entry point for malicious actors to disrupt system operations without requiring any authentication credentials. The vulnerability stems from a fundamental design flaw where the service fails to implement proper access controls, allowing any remote attacker to exploit the functionality directly. This type of vulnerability falls under the CWE-305 authentication weakness category, specifically addressing the absence of proper authentication mechanisms in network services. The impact of this flaw extends beyond simple service disruption as it fundamentally compromises the integrity of the system's access control framework, leaving critical infrastructure components vulnerable to exploitation.
The technical implementation of this vulnerability demonstrates a classic case of insecure network service design where the SocketService module lacks any form of authentication verification before processing incoming requests. The service listens on UDP port 41222, which is a well-known port for industrial communication protocols, making it an attractive target for attackers who can leverage this open access to create service interruptions. The absence of authentication requirements means that an attacker can send malicious packets to this port and trigger the denial-of-service condition without needing to establish any legitimate credentials or permissions. This vulnerability represents a clear violation of the principle of least privilege, where network services should only allow access to authenticated users with appropriate authorization levels. The flaw creates an attack surface that aligns with the ATT&CK technique T1499.004 - Network Denial of Service, specifically targeting the service availability aspect of the attack framework.
The operational impact of CVE-2023-51571 extends beyond immediate service disruption to potentially compromise entire power management systems in industrial environments. Organizations relying on Voltronic Power ViewPower Pro for critical infrastructure monitoring face significant risks including operational downtime, data loss, and potential cascading failures in power distribution systems. The vulnerability's remote exploitability means that attackers can target these systems from anywhere on the network without requiring physical access or legitimate credentials, making it particularly dangerous for industrial control systems. The lack of authentication requirements creates a persistent threat vector that remains active until the underlying software is patched or the service is properly secured. This vulnerability affects systems across various industrial sectors including manufacturing, healthcare, and critical infrastructure where uninterrupted power management is essential for operational continuity.
Mitigation strategies for CVE-2023-51571 must address both immediate defensive measures and long-term architectural improvements to prevent similar vulnerabilities. Organizations should implement network segmentation to isolate the affected SocketService component from critical network segments, effectively limiting the attack surface and preventing unauthorized access to the vulnerable UDP port 41222. The most effective immediate solution involves applying the vendor-provided security patches or updates that address the authentication flaw in the SocketService module. Network administrators should also consider implementing firewall rules to block access to UDP port 41222 from untrusted networks, while maintaining legitimate access for authorized personnel through secure tunneling mechanisms. Additionally, organizations should conduct comprehensive vulnerability assessments to identify other network services that may exhibit similar authentication weaknesses, ensuring that the remediation efforts address the root cause rather than just the symptoms of the vulnerability. The implementation of proper access controls and authentication mechanisms should follow industry standards such as NIST SP 800-53 and ISO 27001 frameworks to establish robust security postures against similar threats.
