Microsoft Windows vulnerability
Microsoft Windows Hyper-V privilege escalation vulnerability (CWE-190) allows local users to gain SYSTEM privileges. Actively exploited in the wild.
Verdict
Today item — known-exploited.
A local privilege escalation in Windows Hyper-V enables attackers with user-level access to obtain SYSTEM-level control. Active exploitation demonstrates immediate risk to Windows environments running Hyper-V.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
7 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 2024-07-09).
Probability (EPSS)
EPSS 0.07115 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Windows . Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-190 Integer Overflow — weakness family: Memory safety.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 gain initial access as a standard user on a Windows system with Hyper-V enabled.
Business
Attacker establishes foothold within the organization's virtualization infrastructure with minimal initial privileges.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the integer overflow vulnerability in Hyper-V to escalate my privileges to SYSTEM level.
Business
Attacker obtains highest operating system privileges, enabling full system compromise and lateral movement.
3
Lateral reach — past segmentation narrative 3
Attacker
I use SYSTEM privileges to install persistence mechanisms, modify security controls, and access sensitive data.
Business
Organization loses control of affected systems; attacker gains ability to exfiltrate data, deploy malware, or sabotage infrastructure.
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.
