AI-analyzed exploit summary This is a Metasploit module for CVE-2013-1300, a kernel pool overflow in Win32k allowing local privilege escalation. It injects a reflective DLL into a process to exploit the vulnerability and migrate into winlogon.exe for SYSTEM privileges.

Description

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT does not properly handle objects in memory, which allows local users to gain privileges via a crafted application, aka "Win32k Memory Allocation Vulnerability."
