Why it matters

— the attack path, told twice: adversary, then board
1

Front door — unauthenticated access narrative 1

Attacker
I execute a malicious GDI operation from my local user account to trigger the vulnerability.
Business
An unprivileged user gains system-level access, enabling full system compromise and lateral movement.
2

Keys to the kingdom — privilege/identity takeover narrative 2

Attacker
I use the elevated privileges to install persistent malware or backdoors on the compromised system.
Business
Attackers establish durable footholds for data exfiltration, espionage, or further network infiltration.
