At a glance
CVE-2020-12054 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Catch Breadcrumb WordPress plugin, affecting versions < 1.5.5. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.5.5; sites on affected versions should update now. Disclosed April 2020, reported by ΞX.MI.
Vulnerability Overview
The Catch Breadcrumb plugin before 1.5.4 for WordPress allows Reflected XSS via the s parameter (a search query). Also affected are 16 themes (if the plugin is enabled) by the same author: Alchemist and Alchemist PRO, Izabel and Izabel PRO, Chique and Chique PRO, Clean Enterprise and Clean Enterprise PRO, Bold Photography PRO, Intuitive PRO, Devotepress PRO, Clean Blocks PRO, Foodoholic PRO, Catch Mag PRO, Catch Wedding PRO, and Higher Education PRO.
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.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Catch Breadcrumb < 1.5.5 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Catch Breadcrumb the fix is 1.5.5: builds < 1.5.5 are affected, anything from 1.5.5 onward is not.
Remediation
Update to version 1.5.5, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Catch Breadcrumb: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Catch Breadcrumb 1.5.5 closes this, and updating the plugin is the step that ends it.
