How to Fix CVE-2019-10803

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

push-dir fixed: Latest secure release 
npm install push-dir@Latest secure release
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 push-dir

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-10803, inspect your project dependencies using npm:

npm ls push-dir

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

Note: The npm ls push-dir 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 Push dir, 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

push-dir through 0.4.1 allows execution of arbritary commands. Arguments provided as part of the variable `opt.branch` is not validated before being provided to the `git` command within [index.js#L139](https://github.com/L33T-KR3W/push-dir/blob/master/index.js#L139). This could be abused by an attacker to inject arbitrary commands.
