CVE-2024-2870
At a glance
CVE-2024-2870 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Swift Framework WordPress plugin, affecting versions < 2024.04.30. 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 2024.04.30; sites on affected versions should update now. Disclosed June 2024, reported by Bob Matyas.
Vulnerability Overview
The Swift Framework plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'listing_id' parameter in all versions up to 2024.04.30 (exclusive) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
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')
Swift Framework < 2024.04.30 carries this weakness at listing_id, and reaching it 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 Swift Framework the fix is 2024.04.30: builds < 2024.04.30 are affected, anything from 2024.04.30 onward is not.
Remediation
Update to version 2024.04.30, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Swift Framework: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Swift Framework 2024.04.30 closes this, and updating the plugin is the step that ends it.
