Trend Micro Apex One and OfficeScan vulnerability
Trend Micro Apex One and OfficeScan contain an unspecified vulnerability in a migration tool component allowing remote code execution.
Verdict
Today item — known-exploited.
A remote code execution flaw in Trend Micro endpoint protection products enables unauthenticated attackers to execute arbitrary code through a migration tool, with active exploitation observed in the wild.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
5 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 2021-11-03).
Probability (EPSS)
EPSS 0.10793 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) · Affected: Trend Micro, Apex One and OfficeScan. Confirm exact fixed builds in the vendor advisory.CVSS — CISA-assigned via the ADP container (CVE.org), version 3.1; the CNA left no metrics, so CISA's own score is used ahead of NVD.
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 595 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.
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 identify and target the exposed migration tool component in Trend Micro Apex One or OfficeScan deployments.
Business
Endpoint security infrastructure becomes a direct attack vector rather than a protective layer.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft and deliver a malicious request to the migration tool to achieve remote code execution on protected systems.
Business
Attackers gain execution privileges on machines that were intended to be hardened and monitored.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistent access and lateral movement across the organization from compromised endpoints.
Business
Enterprise network perimeter defenses are bypassed, enabling widespread internal compromise.
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.
