⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining administrative privileges, data theft, ransomware deployment, and lateral movement within the network.
Likely Case
Remote code execution leading to malware installation, data exfiltration, or system disruption.
If Mitigated
Limited impact with proper network segmentation and file validation controls in place.
🎯 Exploit Status
Exploitation requires user to open a malicious file, but no authentication is needed once the file is processed.
