At a glance

CVE-2015-3986 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the TheCartPress eCommerce Shopping Cart WordPress plugin, affecting versions <= 1.5.3.6. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. 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

Cross-site request forgery (CSRF) vulnerability in the TheCartPress eCommerce Shopping Cart (aka The Professional WordPress eCommerce Plugin) plugin for WordPress before 1.3.9.3 allows remote attackers to hijack the authentication of administrators for requests that conduct directory traversal attacks via 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 privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in TheCartPress eCommerce Shopping Cart <= 1.5.3.6 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. 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.
