⚠️ Risk & Real-World Impact
Worst Case
An attacker with local access could achieve full SYSTEM privilege escalation, enabling complete system compromise, data theft, persistence installation, and lateral movement capabilities.
Likely Case
Malicious users or malware with initial access could escalate privileges to install additional payloads, bypass security controls, and maintain persistence on affected systems.
If Mitigated
With proper privilege separation and application control policies, impact is limited to the user context without SYSTEM access.
🎯 Exploit Status
DLL hijacking vulnerabilities typically have low exploitation complexity once the vulnerable DLL search path is identified. Requires local authenticated access.
