This repository contains a Python exploit script (samsung_account_access.py) and a README.md with usage instructions for exploiting CVE-2021-25374, a vulnerability in certain versions of the Samsung Members app on Android devices (US/Korea region). The exploit works by luring a victim to click a crafted intent link (hosted on the attacker's web server) from their Samsung device. When the victim clicks the link, their device sends SSO tokens to the attacker's server (listening on port 8000). The script then uses these tokens to make authenticated requests to Samsung's account endpoints, extracting the victim's Samsung Account login ID and session cookies. The repository is structured simply, with the main exploit logic in a single Python file and clear instructions in the README. The exploit requires some attacker setup (web server, script running, and social engineering to get the victim to click the link), but is operational and demonstrates the vulnerability effectively.
