An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-21203.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The ViewPower Pro updateManagerPassword function exposes a dangerous function that allows remote attackers to bypass authentication entirely without requiring any credentials. This critical flaw in the password management functionality enables unauthenticated attackers to gain administrative access to the power management system.

MitigationApply vendor patches immediately; until then, restrict network access to the ViewPower Pro management interface to trusted IPs only or disable remote management if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify ViewPower Pro installation
    Check if Voltronicpower ViewPower software is installed on the system. Look for the application in standard installation directories (typically C:\Program Files\ViewPower or C:\Program Files (x86)\ViewPower on Windows) or check system services for 'ViewPower' or 'UPS' related services.
    Affected if ViewPower Pro software is found installed on the system
  2. Verify the installed version number
    Locate the version information for the ViewPower installation. On Windows, this can typically be found in Add/Remove Programs, the application's About dialog, or by checking version metadata in the installation directory. Compare the version to 2.0-22165.
    Affected if The installed version is exactly 2.0-22165
  3. Determine if web management interface is enabled
    Check if the ViewPower Pro web server/service is running and listening on HTTP/HTTPS ports (typically ports 80, 443, 8080, or 8443). Use commands like 'netstat -an | findstr LISTENING' or check the service status.
    Affected if The web management interface is running and accepting connections
  4. Assess network exposure of the management interface
    Determine if the ViewPower web interface is accessible from external network addresses rather than only localhost or 127.0.0.1. Check firewall rules and network configuration to see if the management ports are exposed to untrusted networks.
    Affected if The management interface is accessible from non-localhost/network addresses
  5. Confirm remote management is enabled
    Check the ViewPower configuration settings to verify if remote management/administration features are enabled. This may be found in the application's config files or administrative settings panel.
    Affected if Remote management functionality is enabled in the application configuration

A system is affected if it has ViewPower Pro version 2.0-22165 installed with the web management interface accessible remotely.
