VMware ESXi vulnerability
VMware ESXi authentication bypass via Active Directory group recreation allows privileged AD users to regain full host access after group deletion.
Verdict
Today item, not a backlog item.
An attacker with sufficient Active Directory permissions can bypass ESXi authentication by recreating a deleted AD group configured for host administration, gaining full control of the ESXi host. This vulnerability is actively exploited in ransomware campaigns.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
27 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 2024-07-30), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.25952 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H) · Affected: VMware, ESXi. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-305 CWE-305.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 35 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

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 identify an ESXi host configured to use Active Directory for authentication and locate the administrative group name.
Business
Attacker gains visibility into authentication architecture and administrative group configuration.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I leverage my Active Directory permissions to recreate the deleted administrative group with the same name.
Business
Administrative controls are circumvented through legitimate directory service access.
3
Lateral reach — past segmentation narrative 3
Attacker
I authenticate to the ESXi host using the recreated AD group, obtaining full administrative privileges.
Business
Complete host compromise enables deployment of ransomware, data exfiltration, or lateral movement.

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.
