CVE-2013-3956 is a local privilege escalation vulnerability in the NICM.SYS kernel driver (version 3.1.11.0) used by Novell Client 4.91 SP5 (Windows XP/2003), Novell Client 2 SP2 (Windows Vista/Server 2008), and Novell Client 2 SP3 (Windows 7/8/Server 2008 R2/2012). The vulnerability is triggered by a crafted IOCTL 0x143B6B call, which allows a local attacker to execute arbitrary code in kernel mode, effectively hijacking execution flow within the driver.

This repository contains a single Metasploit module (modules/exploits/windows/local/novell_client_nicm.rb) that exploits a local privilege escalation vulnerability (CVE-2013-3956) in the Novell Client 2 SP3 nicm.sys driver on Windows 7 SP1 (32-bit). The exploit abuses a vulnerable IOCTL handler (0x143B6B) in the driver, which allows a user-supplied pointer to be used as a function pointer in kernel space. The module allocates memory, writes a custom ring0 shellcode to steal the SYSTEM token, and triggers the vulnerability via DeviceIoControl on the \\.\nicm device. Upon successful exploitation, the attacker's privileges are elevated to SYSTEM, and a user-supplied Meterpreter payload is executed. The module is operational and requires a Meterpreter session on a compatible target. The only fingerprintable endpoint is the device path \\.\nicm, which identifies the presence of the vulnerable driver.
