At a glance

CVE-2015-3301 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the TheCartPress eCommerce Shopping Cart WordPress plugin, affecting versions <= 1.5.3.6. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2015, reported by High-Tech Bridge Security Research Lab.

Vulnerability Overview

Directory traversal vulnerability in the TheCartPress eCommerce Shopping Cart (aka The Professional WordPress eCommerce Plugin) plugin for WordPress before 1.3.9.3 allows remote administrators to read arbitrary files via a .. (dot dot) in the tcp_box_path parameter in the checkout_editor_settings page to wp-admin/admin.php.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in TheCartPress eCommerce Shopping Cart <= 1.5.3.6 takes a caller who can reach the endpoint. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. No fixed build of this plugin is recorded for TheCartPress eCommerce Shopping Cart yet, so installs running <= 1.5.3.6 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

The attempt arrives as an ordinary request to TheCartPress eCommerce Shopping Cart: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
