2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit this vulnerability to escalate my privileges from limited user context to administrative level.
Business
Attacker obtains elevated permissions, bypassing access controls protecting sensitive data and system functions.
3
Lateral reach — past segmentation narrative 3
Attacker
I chain this with CVE-2022-41082 to execute arbitrary code with administrative privileges.
Business
Attacker achieves complete system compromise, enabling data theft, malware deployment, and ransomware installation.
4
Data at risk — exfiltration narrative 4

I deploy ransomware or data exfiltration tools across the compromised Exchange environment.
Business
Organization faces operational shutdown, data breach, financial extortion, and regulatory penalties.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
