How to Fix CVE-2022-24437

To remediate this vulnerability, upgrade all affected Git pull or clone 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-pull-or-clone fixed: 2.0.2 
npm install git-pull-or-clone@2.0.2
Verify Direct and Transitive Dependencies

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

npm ls git-pull-or-clone

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-24437, inspect your project dependencies using npm:

npm ls git-pull-or-clone

Analyze the terminal output to locate any version of Git pull or clone in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.2), your application is affected.

Note: The npm ls git-pull-or-clone command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Git pull or clone, 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 package git-pull-or-clone before 2.0.2 is vulnerable to Command Injection due to the use of the --upload-pack feature of git which is also supported for git clone. The source includes the use of the secure child process API spawn(). However, the outpath parameter passed to it may be a command-line argument to the git clone command and result in arbitrary command injection. ## Credits Credit @lirantal for discovering this vulnerability.
