Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.47% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Microsoft Windows 10 Version 1607 and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

Protection mechanism failure in Windows Mark of the Web (MOTW) allows an unauthorized attacker to bypass a security feature over a network.

What

Protection mechanism failure in Windows Mark of the Web (MOTW) allows an unauthorized attacker to bypass a security feature over a network.

Why

The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.

How

An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Protection Mechanism Failure → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction
Required interaction required
Attack complexity
Low: no specialised conditions are recorded
Security boundary

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-693 ↗

CWE-693: Protection Mechanism Failure. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L/E:U/RL:O/RC:C

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CNoneConfidentiality impact: No direct loss is represented by this metric.ILowIntegrity impact: A successful attack can cause a limited loss.ALowAvailability impact: A successful attack can cause a limited loss.

NCSC-NL · Dutch · NCSC-2026-0181Kwetsbaarheden verholpen in Microsoft Windows

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot diverse categorieën schade, zoals omschreven in onderstaande tabellen. Tussen deze kwetsbaarheden zitten een zestal zeer ernstige, welke door Microsoft zijn ingeschaald met een CVSS score van 9 en hoger. Deze kwetsbaarheden bevinden zich in diverse componenten van Windows die bereikbaar en benaderbaar zijn vanaf netwerkverbindingen, zoals http.sys, DHCP, de Kernel en TCP/IP. Door de externe bereikbaarheid en de mogelijkheden tot uitvoer van willekeurige code, is het risico op grootschalig misbruik op korte termijn aanwezig. Op dit moment wordt (nog) geen actief misbruik waargenomen en is (nog) geen publieke Proof-of-Concept (PoC) of exploit bekend, maar het NCSC verwacht deze wel op korte termijn en adviseert daarom deze updates met spoed in te zetten. ``` Windows TCP/IP: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact |
