CVE-2013-3660 is a local privilege-escalation vulnerability in the Microsoft Windows kernel graphics subsystem. The EPATHOBJ::pprFlattenRec function improperly initializes a pointer to the next object in a list. By exhausting paged memory and repeatedly invoking FlattenPath, a local user can obtain write access to the PATHRECORD chain and elevate privileges. Affected versions include Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, and Windows Server 2012.

This repository contains a single Metasploit module (modules/exploits/windows/local/ppr_flatten_rec.rb) that exploits a local privilege escalation vulnerability (CVE-2013-3660) in the Windows kernel (win32k.sys) EPATHOBJ::pprFlattenRec function. The exploit targets Windows XP SP3, Windows 2003 SP1, and Windows 7 SP1 on x86 architecture. The module checks the version of win32k.sys to determine if the target is vulnerable, and if so, uses Reflective DLL Injection to execute a payload (typically a Meterpreter shell) as SYSTEM. The exploit requires an existing Meterpreter session on the target. The structure is typical for a Metasploit local exploit module, with clear separation of initialization, vulnerability checking, and exploitation logic. The only fingerprintable endpoints are the system file win32k.sys (used for version checking) and the DLL payload used for injection.
