Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Windows SmartScreen contains a security feature bypass vulnerability tracked as CVE-2023-24880. The flaw resides in the SmartScreen component of Windows and received a CVSS 4.4 rating reflecting local attack vector, low complexity, no required privileges, and user interaction. It is also associated with CWE-863, indicating improper authorization checks that allow the security control to be circumvented.
An attacker with the ability to execute code on a target system can present specially crafted content that SmartScreen fails to evaluate correctly. Successful exploitation permits limited tampering with integrity and availability properties while bypassing the normal warning or blocking behavior that SmartScreen is intended to enforce.
Microsoft’s security update guide provides patches addressing the issue, and the vulnerability appears in CISA’s catalog of known exploited vulnerabilities, confirming that remediation guidance and fixes have been published through official channels.
EPSS scores for the CVE rose from lower values to a recorded peak of 0.7729 on 2025-12-11 before receding to the current 0.7464, indicating measurable post-disclosure exploitation interest that warrants attention from defenders.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Periodic review and update of procedures reduces incorrect authorization implementations over time.
Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.
Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.
The authorization process and usage restrictions help prevent incorrect authorization for remote access types.
Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.
Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.
Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.
Ensures authorization decisions for external system use are correctly implemented and enforced.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.
Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.
By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
