Analyzing Git Clone Vulnerability

Analyzing Git Clone Vulnerability. A new Git version, 2.30.2, fixes a security vulnerability in Git large file storage (LFS) and other clean/smudge filters affecting Git 2.15 and newer. According to GitHub, if upgrading Git to version 2.30.2 is not an option, users can mitigate their risk in three ways.

A new  Git version, 2.30.2, fixes a security vulnerability in Git large file storage (LFS) and other clean/smudge filters affecting Git 2.15 and newer.

These updates address an issue where a specially crafted repository can execute code during a git clone on case-insensitive file systems which support symbolic links by abusing certain types of clean/smudge filters, like those configured by Git LFS.

Filed under CVE ID  CVE-2021-21300, the vulnerability is of special concern for all users of Windows and macOS systems, which default to using case-insensitive file systems. It can however affect any system, including Linux, that uses a case-insensitive file system to checkout a Git repository.

Python programmer  Foone Turing provided a detailed analysis of the vulnerability in a rather long and detailed Twitter thread. In a nutshell, the exploit requires two steps: getting the lstat cache into an invalid state and reordering checkout operations. One way to get the cache into an invalid state is by abusing a case-insensitive file system by causing a filename collision. Reordering checkout can be accomplished by using a clean/smudge filter with delayed checkout, of which Git LFS is the most notable example. These are the two ingredients that make the exploit possible.
