What is CVE-2018-11235?

This vulnerability in Git allows attackers to execute arbitrary scripts on affected systems when a specially crafted .gitmodules file is processed during the 'git clone --recurse-submodules' operation. The attacker can manipulate the submodule 'names' via directory traversal techniques to append malicious scripts to the $GIT_DIR/modules path. This flaw ultimately leads to the execution of post-checkout hooks, which were designed to remain unattainable from remote repositories, thus circumventing the intended security measures.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
