Vulnerability Overview

Stored XSS in Salutation Responsive WordPress + BuddyPress Theme version 3.0.15 could allow logged-in users to do almost anything an admin can.

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.

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

Reaching this weakness in Salutation Responsive WordPress Theme < 3.0.16 takes any authenticated account. 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 Salutation Responsive WordPress Theme the fix is 3.0.16: builds < 3.0.16 are affected, anything from 3.0.16 onward is not.

Remediation

Update to version 3.0.16, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Salutation Responsive WordPress Theme: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Salutation Responsive WordPress Theme 3.0.16 closes this, and updating the theme is the step that ends it.
