Microsoft Windows NTFS Information Disclosure Vulnerability
What it is
Microsoft Windows New Technology File System (NTFS) contains an insertion of sensitive Information into log file vulnerability that allows an unauthorized attacker to disclose information with a physical attack. An attacker who successfully exploited this vulnerability could potentially read portions of heap memory.
Who's affected
Affects anyone running Windows workstations or servers. In a small CPA, legal, or dental practice, Windows is typically the platform your accounting, document management, or practice management software runs on — exploitation gives an attacker access to whatever client files and credentials live on those machines.
What to do
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
CISA action deadline: April 1, 2025. Federal agencies must complete the required action by this date. For private SMBs the deadline is advisory — but treat it as a strong recommendation, especially if you handle regulated data (HIPAA, GLBA, ABA model rules).
If you don't have someone in-house to verify the patch deployed across every endpoint — or you're not sure whether you're affected — that's exactly the kind of triage we do. Book a free 20-minute triage call.
