Microsoft Windows vulnerability
Microsoft Windows Remote Access Connection Manager contains an improper access control vulnerability allowing authorized attackers to elevate privileges locally.
Verdict
Today item — known-exploited.
An authenticated local attacker can exploit improper access controls in Windows Remote Access Connection Manager to gain elevated privileges on the system. Active exploitation has been observed in the wild.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
8 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 2025-10-14).
Probability (EPSS)
EPSS 0.02615 — 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-284 Improper Access Control — weakness family: Authorization / access control.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 authenticate to the Windows system with standard user credentials.
Business
User account compromise creates initial system access risk.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I identify and exploit improper access controls in the Remote Access Connection Manager component.
Business
Privilege escalation exposes administrative functions to unauthorized modification.
3
Lateral reach — past segmentation narrative 3
Attacker
I elevate my privileges to system or administrator level through the vulnerability.
Business
Full system compromise enables data theft, malware installation, and lateral movement.
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.
