Summary
by MITRE • 08/22/2025
Voltronic Power ViewPower through 1.04-24215, ViewPower Pro through 2.0-22165, and PowerShield Netguard before 1.04-23292 allows a remote attacker to run arbitrary code via an unspecified web interface related to detection of a managed UPS shutting down. An unauthenticated attacker can use this to run arbitrary code immediately regardless of any managed UPS state or presence.

This vulnerability exists in Voltronic Power's ViewPower and PowerShield Netguard software products, representing a critical remote code execution flaw that affects multiple versions of their UPS management systems. The vulnerability specifically resides in the web interface component responsible for detecting managed UPS shutdown events, creating a dangerous attack vector that allows unauthenticated remote exploitation. The flaw enables attackers to execute arbitrary code on affected systems without requiring any authentication credentials or prior access, making it particularly severe in enterprise environments where UPS systems are critical infrastructure components.
The technical nature of this vulnerability stems from improper input validation and sanitization within the web interface's shutdown detection mechanism. When the system processes shutdown notifications from managed UPS units, it fails to properly validate or sanitize incoming data, creating a path for malicious input to be executed as code. This type of vulnerability maps directly to CWE-74, which describes "Improper Neutralization of Special Elements in Output Used by a Downstream Component," and more specifically to CWE-94, "Improper Control of Generation of Code ('Code Injection')." The attack surface is expanded by the fact that the vulnerability can be triggered regardless of actual UPS state or presence, meaning the system's response mechanism can be exploited even when no UPS is connected or operational.
The operational impact of this vulnerability is substantial across enterprise and industrial environments that rely on Voltronic UPS management systems for critical infrastructure protection. An attacker who successfully exploits this vulnerability gains complete control over the affected system, potentially allowing them to manipulate the UPS configuration, disrupt power management operations, or use the compromised system as a foothold for further attacks within the network. In data center or industrial control environments, this could lead to unauthorized power interruption, system instability, or even physical damage to connected equipment. The vulnerability's remote nature means that attackers can exploit it from anywhere on the internet, and the lack of authentication requirements makes it particularly dangerous in environments where these management systems are exposed to external networks.
Organizations should immediately implement network segmentation to isolate affected systems from critical network segments, ensuring that the management interfaces are not directly accessible from untrusted networks. The recommended mitigation strategy includes applying vendor patches as soon as they become available, which should address the input validation flaws in the web interface components. Additionally, implementing network access controls through firewalls and intrusion detection systems can help prevent unauthorized access attempts to the affected management interfaces. Security monitoring should include detection of unusual traffic patterns or attempts to access the shutdown detection interfaces, as specified in the attack techniques described in the MITRE ATT&CK framework under T1210, "Exploitation of Remote Services." Organizations should also conduct comprehensive vulnerability assessments to identify any other systems running affected versions of Voltronic Power software and ensure that all network-connected UPS management systems are properly secured and monitored.
