Vulnerability Details
The official description indicates that CVE-2025-21249 is a Windows Digital Media Elevation of Privilege Vulnerability. It is classified under CWE-125, which pertains to out-of-bounds read vulnerabilities. The CVSS version is 3.1, with a vector string of CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, illustrating that the attack vector is physical, with low complexity and low privileges required.
Affected products include various versions of Windows 10, Windows 11, and Windows Server. The publication date of the vulnerability is January 14, 2025, and its last modified date is January 24, 2025.
Technical Analysis
The root cause of this vulnerability lies in improper validation of input data, allowing attackers to exploit the system through physical access. The attack vector is classified as physical, meaning that an attacker must have physical access to the vulnerable system to exploit this vulnerability.
The attack complexity is low, as only low privileges are required to exploit the vulnerability, and no user interaction is necessary. If successful, attackers may achieve high impacts on confidentiality, integrity, and availability, making this a significant risk.
Risk & Impact Analysis
The real-world deployment risk of CVE-2025-21249 is substantial, particularly for organizations that utilize Microsoft Windows Digital Media. The potential blast radius could affect numerous systems and sensitive data repositories. This vulnerability represents a critical risk for organizations, especially given its potential exploitation through physical access.
Urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. The lack of known public exploits does not diminish the need for immediate action, as the risk of exploitation remains.
