CVE-2023-51583
📋 TL;DR
This vulnerability allows unauthenticated remote attackers to execute arbitrary code with SYSTEM privileges on Voltronic Power ViewPower installations. 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
- Voltronic Power ViewPower
📦 What is this software?
Viewpower by Voltronicpower
⚠️ 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.
🎯 Exploit Status
ZDI-CAN-22036 identifier suggests coordinated disclosure. Unauthenticated RCE with SYSTEM privileges makes weaponization highly probable.
