Vulnerability Overview

An issue was discovered in the File Upload plugin before 4.13.0 for WordPress. A directory traversal can lead to remote code execution by uploading a crafted txt file into the lib directory, because of a wfu_include_lib call.

Technical Analysis

REMEDIATION: Update to version 4.13.0, 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.
