This repository contains a single Metasploit module (modules/exploits/osx/local/libxpc_mitm_ssudo.rb) that exploits CVE-2018-4237, a local privilege escalation vulnerability in Apple's macOS (<= 10.13.3). The exploit leverages a flaw in libxpc and the task_set_special_port API, allowing a man-in-the-middle (MitM) attack on the communication between the sudo binary and opendirectoryd. By intercepting and modifying authentication replies, the exploit tricks sudo into granting root privileges. The module uploads an exploit binary and a payload (defaulting to a Meterpreter reverse shell) to a writable directory (default: /tmp), executes the exploit, and, if successful, provides a root shell to the attacker. The code is written in Ruby and is designed to be run within the Metasploit Framework. The main attack vector is local privilege escalation, requiring prior access to the target system.
