CVE-2025-57489 is a privilege escalation vulnerability in the SDAgent component of Shirt Pocket SuperDuper! version 3.10. The vulnerability arises from incorrect access control and improper use of a setuid binary, which allows attackers to escalate privileges to root. The flaw is due to the SDAgent binary being setuid without sufficient access control checks, enabling unauthorized users to execute it with elevated privileges.

This repository contains a proof-of-concept (POC) exploit for CVE-2025-57489, a local privilege escalation vulnerability in SuperDuper! for macOS (versions prior to 3.11). The exploit leverages the SDAgent setuid binary, which insecurely executes arbitrary shell commands sent via a named pipe without verifying the requesting process. The repository consists of a single Bash script (CVE-2025-57489.sh) that demonstrates how to create a named pipe (/tmp/puppet), use 'tail' to feed commands to SDAgent, and send payloads (such as 'whoami') to be executed as root. The README.md provides a detailed technical analysis, background, and mitigation advice. The exploit requires local access and the SuperDuper! application to be in an unlocked state. No network endpoints are involved; all actions are performed locally via file system paths.
