Newsletters <= 4.6.4.2 - Directory Traversal
Strategic Overview
Vulnerability Overview
The Newsletters plugin for WordPress is vulnerable to directory traversal due to insufficient validation on the data supplied via the 'file' parameter in versions up to, and including 4.6.4.2. This makes it possible for authenticated attackers to access arbitrary files on the system.
Technical Analysis
REMEDIATION: Update to version 4.6.4.3, 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.
