How to Fix CVE-2022-46648

To remediate this vulnerability, upgrade all affected Git dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

git fixed: 1.13.0 
Upgrade git to 1.13.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for git

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-46648, inspect your project dependencies for Git:

inspect dependencies for git

Analyze the terminal output to locate any version of Git in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.13.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Git, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The git gem, between versions 1.2.0 and 1.12.0, incorrectly parsed the output of the `git ls-files` command using `eval()` to unescape quoted file names. If a file name was added to the git repository contained special characters, such as `\n`, then the `git ls-files` command would print the file name in quotes and escape any special characters. If the `Git#ls_files` method encountered a quoted file name it would use `eval()` to unquote and unescape any special characters, leading to potential remote code execution. Version 1.13.0 of the git gem was released which correctly parses any quoted file names.
