Hummingbird <= 3.4.1 - Unauthenticated Path Traversal
Strategic Overview
<= 3.4.1CVE-2023-1478Vulnerability Overview
The Hummingbird plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 3.4.1 via the page cache module, which doesn't validate file paths prior to saving them. This makes it possible for unauthenticated attackers to enumerate file directories, crash to server by sending cache files to an arbitrary location, and write cache files to arbitrary locations that may deny access to some resources.
Technical Analysis
REMEDIATION: Update to version 3.4.2, 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.
