CriticalPublic exploit

Unauthenticated RCE in Voltronic Power ViewPower / ViewPower Pro / PowerShield Netguard

IdentifiersCVE-2022-31491CWE-20

CVE-2022-31491 is a critical remote code execution vulnerability affecting Voltronic Power ViewPower through 1.04-24215, ViewPower Pro through 2.0-22165, and PowerShield Netguard before 1.04-23292. According to the provided content, the flaw is reachable through an unspecified web interface related to detection of a managed UPS shutting down. The issue allows a remote attacker to run arbitrary code, and exploitation does not require authentication. The content further states that exploitation is possible immediately regardless of whether a managed UPS is present or whether any UPS shutdown condition actually exists, indicating that the vulnerable web-exposed functionality can be triggered independently of real device state. Based on the supporting context, the weakness is most consistent with improper input validation in the affected web interface.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows unauthenticated remote arbitrary code execution on the host running the affected UPS monitoring/management software. In operational environments, this can enable full compromise of the management console, manipulation of UPS-related configuration and shutdown logic, disruption of power-management workflows, and use of the compromised system as a foothold for further intrusion. Because these products are used to monitor and control UPS infrastructure, compromise can create high-impact disruption risk in enterprise and ICS/OT environments.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, remove or strictly limit network exposure of the affected web interface, especially from the internet and untrusted networks. Place the management application behind network segmentation and firewall rules, restrict access to dedicated administrative hosts or VPN-only paths, disable or isolate unnecessary web access where operationally feasible, and monitor for unexpected changes to UPS configuration or shutdown logic. Given the unauthenticated nature of the flaw, exposure reduction is critical until remediation is complete.

Remediation

Patch, then assume compromise.

Upgrade to a fixed release: ViewPower newer than 1.04-24215, ViewPower Pro newer than 2.0-22165, and PowerShield Netguard 1.04-23292 or later, as applicable. Apply vendor-provided updates on all systems running the affected UPS monitoring software, verify that exposed web interfaces are updated, and review UPS shutdown/configuration settings for unauthorized changes after patching.
