Spoofing Vulnerability in Windows Security App by Microsoft

CVE-2025-53769

What is CVE-2025-53769?

CVE-2025-53769 is a spoofing vulnerability found in the Windows Security App developed by Microsoft. This application is integrated into Windows operating systems and is designed to provide users with a comprehensive defense against malware and other security threats. The vulnerability arises from an external control of file names or paths, which can be exploited by an authorized attacker. Through this flaw, the attacker can manipulate the application locally, resulting in misleading information being displayed to the user. This could lead to compromised security measures, as users may unknowingly trust deceptive notifications or warnings from the app, undermining the very purpose of the security system.

Potential impact of CVE-2025-53769

1. User Deception: The ability for an attacker to spoof file names or paths within the application can lead to a breakdown of user trust. Users may be misled by false alerts or notifications, potentially causing them to ignore genuine security warnings or inadvertently execute malicious actions.

2. Compromised Security Posture: Organizations relying on the Windows Security App for threat detection may find their defenses weakened. An attacker exploiting this vulnerability could manipulate security settings or display false security statuses, allowing real threats to go undetected and increasing the risk of data breaches or malware infections.

3. Target for Additional Attacks: The existence of this vulnerability could be leveraged by threat actors as a gateway to carry out further attacks within an organization’s network. Once an attacker gains local access through spoofing, they may be able to escalate privileges, access sensitive data, or deploy additional malware, making remediation more challenging.
