CVE-2022-44698: Windows SmartScreen security feature bypass via crafted file

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 17 September 2026. Confidence: medium.

high priorityIt is confirmed exploited in the wild and linked to ransomware campaigns per CISA KEV, but the CVSS impact is limited to a warning bypass (5.4, integrity and availability low) rather than direct code execution.

What it is

CVE-2022-44698 is a security feature bypass in Microsoft Windows SmartScreen, the reputation and warning component that gates untrusted downloads and files. Because the flaw defeats a protective warning rather than a memory boundary, it matters less as a standalone compromise and more as a way to strip a key defense before users open malicious content. The record gives no root-cause detail beyond the generic 'Security Feature Bypass' label.

Impact

An attacker can get a malicious file past SmartScreen's warning and reputation checks, so the user is not shown the usual block or caution prompt. That raises the chance of successful follow-on execution of malware or a malicious document, but the flaw alone does not grant code execution or privilege escalation.

Attack surface

Reached over the network (AV:N) with no privileges required (PR:N), but user interaction is required (UI:R) — typically the victim opening or running a crafted file delivered by web, email or download. No authentication is needed; the attack depends on convincing a user to interact with the file.

Exploitation

CISA added it to the Known Exploited Vulnerabilities catalog on 2022-12-13 with a 2023-01-03 remediation due date and flags known ransomware campaign use, so exploitation in the wild is confirmed. EPSS is very high (0.76267, 99.51st percentile), consistent with active abuse; the references are patch and advisory only and give no exploit detail.

What to do

• Apply the Microsoft update for CVE-2022-44698 on all affected Windows 10, Windows 11 and Windows Server builds as the first action.
• Prioritize internet-facing and user-workstation systems, and treat the CISA KEV due date of 2023-01-03 as the remediation deadline.
• Reduce reliance on SmartScreen alone: enforce attachment and download filtering, block risky file types at the mail and web gateways, and restrict execution of files from untrusted locations.
• Harden endpoints with attack surface reduction rules, application control and EDR blocking of untrusted executables, since the bypass removes a warning rather than a hard control.
• Brief users that SmartScreen warnings may not appear for this flaw, and reinforce reporting of unexpected attachments and downloads.

Detection

• Hunt for processes that execute files from Downloads, Temp or mail attachment cache paths shortly after browser or mail client activity.
• Monitor for SmartScreen or Mark-of-the-Web related events being absent or suppressed for files that should carry reputation checks, and alert on unusual child processes from document readers.
• Correlate endpoint telemetry with known ransomware precursor behavior, given the KEV ransomware flag, and review EDR blocks on untrusted executables.
• Audit patch state across the listed Windows 10, Windows 11 and Windows Server builds to find unpatched hosts.
