Vulnerability Details
The official description of CVE-2025-21341 states that it is a Windows Digital Media Elevation of Privilege Vulnerability. This vulnerability is classified under CWE-125, indicating its relation to out-of-bounds read issues.
The CVSS score for this vulnerability is 6.6, categorized as medium severity. The attack vector is physical, with low complexity required, and it necessitates low privileges without user interaction. The impacts on confidentiality, integrity, and availability are all rated as high.
The vulnerability affects multiple versions of Microsoft Windows, including various editions of Windows 10 and Windows Server. It was published on January 14, 2025.
Technical Analysis
The root cause of CVE-2025-21341 is related to improper handling of certain media files, which could allow an attacker with physical access to a vulnerable system to execute arbitrary code with elevated privileges. The attack vector is physical, meaning an attacker would need to have physical access to the machine to exploit this vulnerability.
The attack complexity is categorized as low, suggesting that a potential attacker could exploit the vulnerability easily under the right conditions. Privileges required for exploitation are low, meaning that even an unprivileged user could potentially exploit this vulnerability if they have physical access to the machine.
User interaction is not required for exploitation, which increases the risk of this vulnerability being exploited in environments where physical access can be obtained by unauthorized personnel.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-21341 is significant. Attackers may leverage this vulnerability to gain unauthorized access to sensitive information, which can lead to data breaches and loss of confidential data.
Given the potential for high impact on confidentiality, integrity, and availability, organizations should take immediate action to patch affected systems. The blast radius for this vulnerability could extend beyond the initial system if exploited, affecting interconnected systems or sensitive databases.
The urgency to address this vulnerability is high, considering its exploitation potential and the high impact on vital system functions and data integrity.
