⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control, data theft, system disruption, and potential lateral movement within the network.
Likely Case
Local privilege escalation leading to unauthorized access to sensitive simulation data and potential disruption of simulation operations.
If Mitigated
Limited impact with proper file validation and user awareness preventing malicious file execution.
🎯 Exploit Status
Requires user interaction (opening malicious file) and buffer overflow exploitation knowledge
