This repository contains a single Metasploit module (modules/exploits/windows/local/virtual_box_guest_additions.rb) that exploits a local privilege escalation vulnerability (CVE-2014-2477) in the VBoxGuest.sys driver, part of Oracle VirtualBox Guest Additions up to version 4.3.10r93012, on Windows XP SP3 systems. The exploit works by opening a handle to the \\.\vboxguest device, disclosing the HalDispatchTable address, and injecting custom shellcode into kernel memory. The shellcode overwrites HalDispatchTable+0x4 to point to attacker-controlled code, which is then executed via NtQueryIntervalProfile, allowing the attacker to steal the SYSTEM token and execute arbitrary code as SYSTEM. The module is operational and requires a Meterpreter session on the target. The main fingerprintable endpoints are the device path (\\.\vboxguest), the driver file (%WINDIR%\system32\drivers\vboxguest.sys), and the hal.dll system file. The repository is structured as a typical Metasploit exploit module, written in Ruby, and is focused solely on this exploit.
