CVE-2022-31491
Voltronic · Voltronic Power ViewPower, ViewPower Pro, and PowerShield Netguard
A critical remote code execution vulnerability, rated with the maximum CVSS score of 10, has been identified in multiple Voltronic Power software products.
Executive summary
A critical remote code execution vulnerability, rated with the maximum CVSS score of 10, has been identified in multiple Voltronic Power software products. This flaw allows an unauthenticated attacker to take complete control of affected systems over the network, potentially leading to severe disruption of power management infrastructure, data breaches, and further network compromise. Immediate patching is required to mitigate this severe risk.
Vulnerability
This vulnerability allows a remote, unauthenticated attacker to execute arbitrary code on the server running the affected software. The flaw exists within an unspecified web interface, which fails to properly sanitize user-supplied input. An attacker can craft a malicious request to this interface to execute commands with the privileges of the application, leading to a full system compromise.
Business impact
This vulnerability is of critical severity with a CVSS score of 10. Successful exploitation would grant an attacker complete control over the power management software and the underlying server. This could lead to catastrophic business impacts, including the deliberate shutdown of critical power systems, manipulation of power monitoring data, theft of sensitive system or network information, and using the compromised server as a pivot point to launch further attacks against the internal network. The potential consequences include significant operational downtime, financial loss, reputational damage, and a complete breach of the system's confidentiality, integrity, and availability.
Remediation
Immediate Action: Immediately identify all instances of the affected software and update them to the latest patched versions as recommended by the vendor. After patching, review web server and system access logs for any signs of compromise or suspicious activity predating the update.
Proactive Monitoring: Implement enhanced monitoring on affected systems. Look for unusual or malformed requests to the web interface in access logs, unexpected processes or services running on the server, and anomalous outbound network traffic. Intrusion Detection/Prevention Systems (IDS/IPS) should be updated with signatures to detect and block known exploitation attempts.
Compensating Controls: If immediate patching is not feasible, restrict network access to the vulnerable web interface. Use a firewall to limit access to only trusted administrative workstations or place the affected systems on a segmented, isolated network. A Web Application Firewall (WAF) can also be deployed to inspect and block malicious web requests.
Exploitation status
Public Exploit Available: true
Analyst recommendation
This vulnerability poses a critical and immediate threat to the organization. Due to the perfect CVSS score, the public availability of exploit code, and the potential for complete system compromise via a low-complexity remote attack, immediate action is imperative. All affected Voltronic Power software must be patched without delay. The absence of this CVE from the CISA KEV catalog should not be interpreted as a low risk; organizations must assume they are an active target and apply remediation or compensating controls immediately.
