Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1

2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I invoke the vulnerable cPanel plugin interface to escalate my privileges to root.
Business
Attacker gains administrative control over the entire server, enabling data theft, malware deployment, and service disruption.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary scripts with root privileges to establish persistence and lateral movement.
Business
Compromise spreads across multiple customer accounts and infrastructure, requiring incident response, forensics, and potential customer notification.
