How to Fix CVE-2018-1002203

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

unzipper fixed: 0.8.13 
npm install unzipper@0.8.13
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 unzipper

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-1002203, inspect your project dependencies using npm:

npm ls unzipper

Analyze the terminal output to locate any version of Unzipper in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.13), your application is affected.

Note: The npm ls unzipper 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Unzipper, 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

Versions of `unzipper` before 0.8.13 are vulnerable to arbitrary file write when used to extract a specifically crafted archive that contains path traversal filenames (`../../file.txt` for example). ## Recommendation Update to version 0.3.18 or later.
