Microsoft Kerberos Key Distribution Center (KDC) vulnerability
The Kerberos KDC in Microsoft allows authenticated domain users to escalate privileges to domain administrator level through a flaw in the authentication mechanism.
Verdict
Today item — known-exploited.
Authenticated domain users can exploit a privilege escalation vulnerability in the Kerberos Key Distribution Center to gain domain administrator access, enabling complete compromise of Active Directory infrastructure and all connected systems.
01

— the evidence, ranked above the scoreReported exploitation
9 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2022-03-25).
Probability (EPSS)
EPSS 0.87448 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Kerberos Key Distribution Center (KDC). Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-264 Permissions/Privileges/Access Control — weakness family: Authorization / access control.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I authenticate to the domain as a standard user with valid credentials.
Business
An insider or compromised standard user account becomes a pivot point for lateral movement.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the KDC vulnerability to escalate my privileges to domain administrator level.
Business
Administrative access is obtained without detection of privilege grant through normal channels.
3
Lateral reach — past segmentation narrative 3
Attacker
I gain full control over the Active Directory infrastructure and all domain-joined systems.
Business
Complete compromise of the organization's identity and access management system, enabling data theft, system manipulation, and persistent backdoor installation.
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.
