Vulnerability Overview

The The REHub - Price Comparison, Multi Vendor Marketplace Wordpress Theme theme for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 19.9.7.

This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

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, and no interaction from a victim user.

CWE-94: Improper Control of Generation of Code ('Code Injection')

Reaching this weakness in REHub - Price Comparison, Multi Vendor Marketplace Wordpress Theme <= 19.9.7 takes no account at all. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For REHub - Price Comparison, Multi Vendor Marketplace Wordpress Theme the fix is 19.9.8: builds <= 19.9.7 are affected, anything from 19.9.8 onward is not.

Remediation

Update to version 19.9.8, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: REHub - Price Comparison, Multi Vendor Marketplace Wordpress Theme 19.9.8 closes this, and updating the theme is the step that ends it.
