Executive brief
A security vulnerability exists in the way Windows handles Human Interface Devices (HID), such as keyboards and mice. An attacker who already has basic access to a computer could exploit this flaw to view sensitive information that should normally be protected. While the attacker must already be logged into the system, this could lead to the unauthorized disclosure of private data.
Technical details
This vulnerability is classified as an integer overflow or wraparound (CWE-190) within the Windows Devices Human Interface component. An attacker with local access and low privileges can exploit this flaw to trigger an incorrect memory calculation, leading to unauthorized information disclosure. The attack requires the attacker to be authenticated and has a high complexity (AC:H), suggesting specific timing or environmental conditions are necessary for successful exploitation. Microsoft has released security updates to address this issue across multiple versions of Windows 10, Windows 11, and Windows Server.
