Microsoft ATM Font Driver vulnerability
A privilege escalation vulnerability in Microsoft's ATM Font Driver allows local users to gain elevated privileges through a crafted application.
Verdict
Today item — known-exploited.
Local attackers can exploit this vulnerability to escalate privileges on affected Windows systems. The vulnerability has been observed in active exploitation in the wild, though it does not appear associated with ransomware campaigns.
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
10 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 2022-03-03).
Probability (EPSS)
EPSS 0.36738 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, ATM Font Driver. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-264 Permissions/Privileges/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 craft a malicious application that triggers improper access control in ATMFD.DLL to execute code with elevated privileges.
Business
An unprivileged user account on a Windows system is compromised, enabling lateral movement and deeper system compromise.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I leverage the elevated privileges to install persistent backdoors or modify system configurations.
Business
Attackers gain sustained access to critical infrastructure, increasing risk of data theft, system manipulation, or further network 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.
