What is CVE-2015-0004?
CVE-2015-0004 is an elevation of privilege vulnerability that affects the Microsoft User Profile Service (ProfSvc) in multiple versions of the Windows operating system, including Windows Server 2003 SP2, Windows Vista SP2, and Windows 7 SP1, among others. This vulnerability allows local users to escalate their privileges by conducting a junction attack, which involves manipulating the UsrClass.dat registry hive of another user. Such exploitation can enable unauthorized access to sensitive system functions or user data, undermining the integrity and security of the affected system. Organizations that utilize these versions of Windows are particularly at risk, as the vulnerability could facilitate unauthorized administrative access, leading to potential system compromise and data loss.
Potential impact of CVE-2015-0004
-
