CVE-2024-5930
📋 TL;DR
This vulnerability allows local attackers with low-privileged access to escalate privileges to SYSTEM level by exploiting incorrect file permissions in VIPRE Advanced Security's Anti Malware Service. Affected installations of VIPRE Advanced Security on Windows systems are vulnerable to complete system compromise.
💻 Affected Systems
- VIPRE Advanced Security
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with SYSTEM privileges, enabling installation of persistent malware, credential theft, lateral movement, and data exfiltration.
Likely Case
Local privilege escalation leading to persistence mechanisms, disabling security controls, and credential harvesting from the compromised system.
If Mitigated
Limited impact if proper endpoint security controls, least privilege principles, and network segmentation are implemented.
🎯 Exploit Status
Exploitation requires local access and low-privileged code execution first. The vulnerability is in file permissions, making exploitation straightforward once initial access is achieved.
