At a glance

CVE-2022-0884 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the User Profile Builder WordPress plugin, affecting versions < 3.6.8. It carries a CVSS score of 5.5 (reachable over the network; high confidentiality impact). The issue is fixed in version 3.6.8; sites on affected versions should update now. Disclosed March 2022, reported by Abhinav Porwal.

Vulnerability Overview

The Profile Builder WordPress plugin before 3.6.8 does not sanitise and escape Form Fields titles and description, which could allow high privilege user such as admin to perform Criss-Site Scripting attacks even when unfiltered_html is disallowed

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in User Profile Builder < 3.6.8 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 User Profile Builder the fix is 3.6.8: builds < 3.6.8 are affected, anything from 3.6.8 onward is not.

Remediation

Update to version 3.6.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to User Profile Builder: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: User Profile Builder 3.6.8 closes this, and updating the plugin is the step that ends it.
