Microsoft DWM Core Library vulnerability
Microsoft DWM Core Library privilege escalation vulnerability (CWE-122) allows attackers to gain SYSTEM privileges. Actively exploited in the wild and leveraged in ransomware campaigns.
Verdict
Today item, not a backlog item.
A buffer overflow in DWM Core Library enables local privilege escalation to SYSTEM level. The vulnerability is under active exploitation and has been weaponized in ransomware operations, posing significant risk to Windows systems.
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
14 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 2024-05-14), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.05687 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, DWM Core Library. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-122 Heap-based Buffer 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 to a Windows system through phishing, malware delivery, or existing compromise with limited user privileges.
Business
Attacker establishes foothold on corporate endpoint, bypassing initial access controls.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I trigger the buffer overflow in DWM Core Library to escalate my privileges from user to SYSTEM level.
Business
Attacker obtains highest system privileges, enabling lateral movement and persistence across the network.
3
Lateral reach — past segmentation narrative 3
Attacker
I deploy ransomware or additional malicious payloads with SYSTEM privileges across the compromised environment.
Business
Ransomware encrypts critical business data and systems, resulting in operational shutdown and extortion demands.
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.
