Verdict
Today item — known-exploited.
A local attacker can exploit type confusion in COM+ Event System Service to escalate privileges on affected Windows systems. The vulnerability has been observed in active exploitation.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
4 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 2022-10-11).
Probability (EPSS)
EPSS 0.01777 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Windows COM+ Event System Service. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-843 Type Confusion — 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 craft a malicious COM+ event object that exploits type confusion in the Event System Service.
Business
An unprivileged user gains system-level code execution on the affected Windows host.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary code with elevated privileges to install backdoors or lateral movement tools.
Business
Attackers establish persistent access to critical infrastructure and expand compromise across the network.
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.
