⚠️ Risk & Real-World Impact
Worst Case
Attacker gains SYSTEM privileges, enabling complete system compromise, data theft, persistence establishment, and disabling of security controls.
Likely Case
Local privilege escalation leading to installation of malware, credential harvesting, and lateral movement within the network.
If Mitigated
Limited impact if proper endpoint protection, least privilege principles, and network segmentation are implemented.
🎯 Exploit Status
Exploitation requires local access and low-privileged code execution; ZDI advisory suggests weaponization is likely given the nature of the vulnerability.
