CVE-2014-4113 is a high-severity vulnerability in the Microsoft Win32k component, specifically within the kernel-mode drivers of various Windows operating systems, including Windows 7, Windows 8, and Windows Server versions. This vulnerability allows local users to gain privileges via a crafted application. First disclosed in October 2014, CVE-2014-4113 has been actively exploited, posing significant risks to organizations that have not applied the necessary patches.
With a CVSS score of 7.8, the vulnerability is classified as high severity. This score indicates a substantial risk, as attackers may leverage this vulnerability to escalate privileges and execute unauthorized actions within the affected systems. Organizations need to recognize that this vulnerability can lead to severe consequences if left unpatched.
As of the last update, CVE-2014-4113 remains a concern for various versions of Windows, including Windows Server 2003, 2008, and 2012, along with Windows Vista and 8.1. Given its history of exploitation, organizations should prioritize patching immediately.
The urgency for defenders is underscored by the high potential for exploitation, particularly in environments that still run affected versions. Organizations are advised to conduct a thorough review of their systems to ensure that all patches are applied promptly.
Vulnerability Details
The vulnerability involves win32k.sys in the kernel-mode drivers across several Microsoft Windows operating systems, allowing local users to gain elevated privileges through a crafted application. The official CVE description classifies this as the "Win32k.sys Elevation of Privilege Vulnerability." The vulnerability's CVSS score is 7.8, indicating a high severity level.
The affected products include Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1. It was published on October 15, 2014, and classified under CWE-264.
Technical Analysis
The root cause of CVE-2014-4113 stems from improper handling of certain user inputs in the win32k.sys component, which is fundamental for managing various graphical and user interface elements in Windows systems. The attack vector is local, meaning it requires physical or remote access to the affected system. The complexity of the attack is low, as it does not require any special conditions to exploit.
No privileges are required to initiate an attack, but user interaction is necessary, as the crafted application must be executed by the victim. The impacts of this vulnerability include high confidentiality, integrity, and availability impacts, allowing attackers to execute arbitrary code within the context of the user.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2014-4113 is significant, especially for organizations still using outdated Windows versions. The blast radius could be extensive if an attacker successfully exploits this vulnerability, leading to unauthorized access and control over sensitive data and systems.
Organizations should assess the urgency based on the CVSS score of 7.8, indicating a high priority for patching. The known exploitation in the wild further emphasizes the need for immediate action to protect against potential attacks.
