Vulnerability Overview

The WPvivid backup plugin for WordPress is vulnerable to arbitrary file read due to missing parameter sanitization and validation on the 'file_name' parameter in versions up to, and including, 0.9.75. This makes it possible for authenticated attackers, with administrator level permissions and above, to access arbitrary files on the affected sites server.

Technical Analysis

REMEDIATION: Update to version 0.9.76, 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.
