Microsoft Windows contains a vulnerability that could allow a local attacker to gain elevated privileges. Updates are available.
Microsoft Windows contains a vulnerability that could allow a local attacker to gain elevated privileges.
The vulnerability is due to the improper handling of certain objects in memory by the affected software. A local attacker with access to a targeted system could exploit this vulnerability by inserting a malicious USB device into the targeted system that is designed to cause the Windows kernel to perform improper memory operations on certain objects. If successful, the attacker could execute arbitrary code on the system with the privileges of the kernel.
Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
The following Microsoft products are affected:
Windows XP SP3 and Professional x64 Edition SP2
Windows Server 2003, x64 Edition and Itanium-based Systems SP2
Windows Vista and x64 Edition SP2
Windows Server 2008 for 32-bit, x64-based Systems and Itanium-based Systems SP2
Windows 7 for 32-bit and x64-based Systems SP1 and prior
Windows Server 2008 R2 for x64-based and Itanium-based Systems SP1 and prior
Windows 8 for 32-bit and 64-bit Systems
Windows Server 2012
To exploit the vulnerability, an attacker would need to log in locally to a system. This access requirement limits the potential for successful exploitation.
Microsoft has corrected this vulnerability by modifying the way Windows kernel-mode driver handles objects in memory.
Microsoft has released a security bulletin at the following link: MS13-027
A local attacker could exploit this vulnerability to gain elevated privileges on a targeted system. Successful exploitation could result in a complete system compromise.
The vulnerability is due to the improper handling of objects in memory by the Windows USB drivers in the affected software.
A local attacker with access to a targeted system could exploit this vulnerability by inserting a malicious USB device into the targeted system that is designed to cause the Windows kernel to perform improper memory operations on certain objects. If successful, the attacker could execute arbitrary code on the system with the privileges of the kernel.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to access local systems.
Administrators may consider using the Microsoft Baseline Security Analyzer (MBSA) scan tool to identify common security misconfigurations and missing security updates on system endpoints.
Administrators are advised to monitor critical systems.
Microsoft customers can obtain updates directly by using the links in the security bulletin. These updates are also distributed by Windows automatic update features and available on the Microsoft Update service. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
