How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-1002207, inspect your project dependencies for Github.com/mholt/archiver:

inspect dependencies for github.com/mholt/archiver

Analyze the terminal output to locate any version of Github.com/mholt/archiver in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.0), 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-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 Github.com/mholt/archiver, 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

mholt/archiver golang package before e4ef56d48eb029648b0e895bb0b6a393ef0829c3 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in an archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'.
