Vulnerability Details
The official description of CVE-2025-47956 states that external control of file name or path in the Windows Security App allows an authorized attacker to perform spoofing locally. This vulnerability is classified under CWE-73, which pertains to external control of file name or path.
The CVSS score is 5.5, indicating a medium severity level. This score is derived from the vulnerability's characteristics, including a local attack vector, low attack complexity, and low privileges required for exploitation. The confidentiality impact is high, while integrity and availability impacts are none.
Affected products include the Windows Security App, with the specific version being all versions prior to the vendor patch. The vulnerability was published on June 10, 2025.
Technical Analysis
The root cause of this vulnerability is the lack of proper validation of external inputs, allowing attackers to manipulate file names or paths. The attack vector is local, meaning the attacker must have access to the affected system to exploit the vulnerability.
The attack complexity is low, as the attacker requires only low privileges and no user interaction is needed. While the confidentiality impact is high, there are no impacts to integrity or availability.
Risk & Impact Analysis
The real-world deployment risk of CVE-2025-47956 is significant due to the potential for local spoofing attacks. Attackers may leverage this vulnerability to perform unauthorized actions on the system, which can have a critical impact on organizational security.
The blast radius potential is moderate, as the vulnerability primarily affects users with local access to the system. Organizations should assess the urgency of addressing this vulnerability based on their specific deployment and usage of the Windows Security App.
Given the CVSS score of 5.5 and the absence of known exploits, organizations should address this vulnerability in their priority patch cycle.
