CVE-2020-1485 in Windows
Summary
by MITRE
An information disclosure vulnerability exists when the Windows Image Acquisition (WIA) Service improperly discloses contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system. To exploit the vulnerability, an authenticated attacker could connect an imaging device (camera, scanner, cellular phone) to an affected system and run a specially crafted application to disclose information. The security update addresses the vulnerability by correcting how the WIA Service handles objects in memory.

The CVE-2020-1485 vulnerability represents a critical information disclosure flaw within the Windows Image Acquisition WIA service that has significant implications for system security and user privacy. This vulnerability specifically affects the Windows operating system's handling of imaging device communications and memory management. The WIA service is designed to facilitate communication between imaging devices such as cameras, scanners, and mobile devices with the Windows operating system, creating a legitimate pathway for device interaction that unfortunately also exposes potential attack vectors.
The technical flaw in CVE-2020-1485 stems from improper memory handling within the WIA service implementation where the service fails to adequately protect sensitive data structures and objects stored in memory during device communication processes. When an imaging device connects to a system running an affected Windows version, the WIA service processes device-specific data and maintains various memory objects that contain information about the device capabilities, communication parameters, and potentially sensitive system data. The vulnerability manifests when the service does not properly sanitize or protect these memory contents, allowing unauthorized access to information that should remain confidential. This memory disclosure occurs during the normal operation of device communication rather than through explicit exploitation, making it particularly dangerous as it can be triggered through legitimate device connections.
From an operational perspective, this vulnerability creates a substantial risk for authenticated attackers who can leverage the flaw by simply connecting a compatible imaging device to an affected system. The attack requires minimal privileges since the attacker only needs to be authenticated to the system and must have access to an imaging device such as a camera, scanner, or mobile phone. The exploitation process involves running a specially crafted application that communicates with the WIA service through the connected device, triggering the memory disclosure mechanism. The impact of such information disclosure can be severe as the leaked memory contents may include sensitive system information, device configuration details, communication protocols, or even partial system state information that could be used for further attacks. This vulnerability essentially provides an attacker with additional reconnaissance data that could be combined with other exploits to escalate privileges or compromise additional system components.
The security update for CVE-2020-1485 addresses this issue by modifying how the WIA service manages objects in memory, implementing proper memory protection mechanisms and ensuring that sensitive data structures are adequately sanitized before being exposed through device communication channels. This remediation aligns with common security practices for preventing information disclosure vulnerabilities and follows the principle of least privilege by ensuring that only necessary information is accessible through the WIA service interface. The fix specifically targets the memory handling routines within the Windows Image Acquisition service, preventing the accidental exposure of internal data structures that could otherwise be accessed through legitimate device connection pathways. Organizations should prioritize applying this update as it directly addresses a vulnerability that could be exploited by attackers with minimal access requirements, making it a critical component of overall system security posture. The vulnerability's classification aligns with CWE-200 (Information Exposure) and may be related to ATT&CK techniques involving reconnaissance and privilege escalation through information gathering.
