CVE-2012-1528

Vulnerability

CVE-2012-1528 is an integer overflow vulnerability in Windows Shell affecting Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, Windows 8, and Windows Server 2012 [1]. The flaw is triggered when Windows Explorer processes a specially crafted briefcase file, leading to memory corruption [1].

Exploitation

An attacker can exploit this vulnerability by convincing a user to browse to a malicious briefcase file in Windows Explorer, either by opening it locally or accessing a network share [1]. The user does not need elevated privileges, but the attacker must be on the same system or network [1]. Successful exploitation depends on the user's interaction with the crafted file [1].

Impact

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the current user [1]. If the user has administrative rights, the attacker can gain complete control of the system, including installing programs, viewing, changing, or deleting data, and creating new accounts with full user rights [1]. The vulnerability is rated Critical due to the potential for remote code execution leading to full system compromise [1].

Mitigation

Microsoft released security update MS12-072 on November 13, 2012, which addresses this vulnerability by modifying how Windows Shell handles briefcase files [1]. Administrators should apply the update via Windows Update or manual installation [1]. No workarounds are documented in the available references [1][2][3]. Users are advised to keep automatic updates enabled [1].
