Vulnerability Overview

WordPress Plugin Simple File List before 4.2.8 is prone to a vulnerability that lets attackers delete arbitrary files because the application fails to properly verify user-supplied input.

Technical Analysis

REMEDIATION: Update to version 4.2.8, or a newer patched version --- IDENTIFIER: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) 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.
