CVE-2011-2005 is a local elevation-of-privilege vulnerability in afd.sys, the Ancillary Function Driver component in Microsoft Windows XP SP2/SP3 and Windows Server 2003 SP2. The flaw is caused by improper validation of user-mode input passed into kernel mode by the driver. A local attacker can supply crafted input via a malicious application to trigger the vulnerability and execute code with elevated privileges in kernel context. Microsoft refers to this issue as the "Ancillary Function Driver Elevation of Privilege Vulnerability."

This repository contains a single Metasploit module (ms11_080_afdjoinleaf.rb) that exploits the MS11-080 vulnerability (CVE-2011-2005) in the afd.sys driver on Windows XP SP2/SP3 and Windows Server 2003 SP2 (x86). The exploit leverages a flaw in the AfdJoinLeaf function to overwrite the HalDispatchTable in kernel memory, redirecting execution to attacker-supplied shellcode. Upon successful exploitation, the module elevates the current session to SYSTEM privileges and injects a customizable Meterpreter payload into a SYSTEM process, then restores its own token to minimize system instability. The exploit is operational and requires a Meterpreter session on a vulnerable system. The code is written in Ruby and is structured as a standard Metasploit local privilege escalation module, with clear targeting of specific Windows versions and kernel structures. Notable fingerprintable endpoints include the afd.sys and hal.dll drivers, as well as the HalDispatchTable. The exploit avoids injecting into critical processes like lsass.exe, csrss.exe, and smss.exe to prevent system crashes.
