CVE-2025-48384 PoC — Git allows arbitrary code execution through broken config quoting

Title:Git allows arbitrary code execution through broken config quoting (CVE-2025-48384)
Description:Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if the submodule path contains a trailing CR, the altered path is read resulting in the submodule being checked out to an incorrect location. If a symlink exists that points the altered path to the submodule hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.

# PoC for CVE-2025-48384

This proof-of-concept demonstrates Git's CR-path submodule misparsing vulnerability, leading to arbitrary hook execution during `git clone --recurse-submodules`.

## ⚠️ Warning
This is **for educational and testing purposes only**. Do **not** run this on any production environment.
