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 Guard livereload, 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 vulnerability allows remote attackers to read arbitrary files on the server by exploiting improper path validation in the livereload server functionality. This vulnerability is related to the handling of file paths in the livereload server component, which could allow an attacker to traverse directories and access files outside the intended web root directory. The issue was identified and reported through the DWF (Distributed Weakness Filing) project, which assigns CVE identifiers for security vulnerabilities. A directory traversal vulnerability exists in guard-livereload before version 2.5.2.
