The flaw exists in the UpsScheduler class where an exposed dangerous method can be exploited. All users running vulnerable versions of Voltronic Power ViewPower are affected.

💻 Affected Systems

Products:
  • Voltronic Power ViewPower
Versions: Specific versions not detailed in advisory, but all versions containing the vulnerable UpsScheduler class
Operating Systems: Windows (based on SYSTEM context exploitation)
Default Config Vulnerable: ⚠️ Yes
Notes: Authentication is not required to exploit this vulnerability. The vulnerability exists in the UpsScheduler class implementation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise with SYSTEM privileges, allowing attackers to install malware, steal data, pivot to other systems, or disrupt critical power management operations.

🟠

Likely Case

Remote code execution leading to ransomware deployment, data exfiltration, or creation of persistent backdoors on affected systems.

🟢

If Mitigated

Limited impact if systems are isolated behind firewalls with strict network segmentation and proper access controls.

🌐 Internet-Facing: HIGH - Unauthenticated remote exploitation with CVSS 9.8 score makes internet-facing systems extremely vulnerable.
🏢 Internal Only: HIGH - Even internally, unauthenticated exploitation allows lateral movement within networks.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

ZDI-CAN-22036 identifier suggests coordinated disclosure. Unauthenticated RCE with SYSTEM privileges makes weaponization highly probable.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check with Voltronic Power for specific patched versions

Vendor Advisory: https://www.zerodayinitiative.com/advisories/ZDI-23-1888/

Restart Required: Yes

Instructions:

1. Contact Voltronic Power for security updates. 2. Apply the latest security patch. 3. Restart affected systems. 4. Verify the patch is properly installed.

🔧 Temporary Workarounds

Network Isolation

all

Isolate Voltronic Power ViewPower systems from untrusted networks and internet access

Configure firewall rules to block external access to ViewPower services

Access Control Restrictions

all

Implement strict network segmentation and access controls

Use VLANs, firewall rules, and network policies to restrict access to necessary IPs only

🧯 If You Can't Patch

  • Immediately isolate affected systems from all networks, especially internet-facing connections
  • Implement strict firewall rules allowing only essential traffic from trusted sources

🔍 How to Verify

Check if Vulnerable:

Check if Voltronic Power ViewPower is installed and running. Review version against vendor advisories.

Check Version:

Check application version through ViewPower interface or installation directory properties

Verify Fix Applied:

Verify patch installation through vendor-provided verification methods and test system functionality

📡 Detection & Monitoring

Log Indicators:

  • Unusual process creation events, especially with SYSTEM privileges
  • Unexpected network connections to/from ViewPower systems
  • Failed authentication attempts followed by successful exploitation

Network Indicators:

  • Unusual traffic patterns to ViewPower ports
  • Exploitation attempts detected via IDS/IPS signatures

SIEM Query:

source="ViewPower" AND (event_type="process_creation" OR event_type="network_connection") AND user="SYSTEM"
