At a glance

CVE-2022-4236 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Welcart e-Commerce WordPress plugin, affecting versions <= 2.8.4. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.8.5; sites on affected versions should update now. Disclosed December 2022, reported by WPScanTeam.

Vulnerability Overview

The Welcart e-Commerce plugin for WordPress is vulnerable to arbitrary file read due to missing restrictions to proper file paths in one of its AJAX actions in versions 2.6.10-2.8.4. This makes it possible for authenticated attackers, with subscriber-level access and higher, to read arbitrary files on the affected sites server leading to information disclosure.

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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Welcart e-Commerce <= 2.8.4 takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Welcart e-Commerce the fix is 2.8.5: builds <= 2.8.4 are affected, anything from 2.8.5 onward is not.

Remediation

Update to version 2.8.5, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Welcart e-Commerce 2.8.5 closes this, and updating the plugin is the step that ends it.
