CVE-2023-51588
📋 TL;DR
This vulnerability allows local attackers with initial low-privileged access to escalate to SYSTEM privileges on Voltronic Power ViewPower Pro installations. Attackers exploit hard-coded MySQL database credentials to execute arbitrary code. Only systems running the affected software are vulnerable.
💻 Affected Systems
- Voltronic Power ViewPower Pro
📦 What is this software?
Viewpower by Voltronicpower
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with SYSTEM privileges, enabling installation of persistent malware, data theft, and lateral movement across the network.
Likely Case
Local privilege escalation allowing attackers to bypass security controls, install additional tools, and maintain persistence on compromised systems.
If Mitigated
Limited impact if proper network segmentation, least privilege principles, and monitoring are implemented to detect unusual local privilege escalation attempts.
🎯 Exploit Status
Exploitation requires existing local access. The vulnerability is straightforward to exploit once an attacker gains initial foothold.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Change MySQL Credentials
windowsManually change the hard-coded MySQL credentials to strong, unique passwords
mysql -u root -p
ALTER USER 'viewpower'@'localhost' IDENTIFIED BY 'NewStrongPassword123!';
FLUSH PRIVILEGES;
Restrict Local Access
allImplement strict access controls to limit who can log into systems running ViewPower Pro
🧯 If You Can't Patch
- Implement network segmentation to isolate ViewPower Pro systems from critical infrastructure
- Deploy endpoint detection and response (EDR) solutions to monitor for privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check if Voltronic Power ViewPower Pro is installed and review MySQL configuration files for hard-coded credentialsCheck Version:
Check ViewPower Pro application version through its interface or installation directoryVerify Fix Applied:
Verify with vendor that patch has been applied and test that hard-coded credentials no longer work📡 Detection & Monitoring
