CVE-2018-6001
At a glance
CVE-2018-6001 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Soundy Audio Playlist WordPress plugin, affecting versions <= 4.6. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed January 2018, reported by DefenceCode.
Vulnerability Overview
The Soundy Audio Playlist plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.6. This is due to missing or incorrect nonce validation on the 'soundy-audio-playlist\templates\front-end.php (war_sdy_pl_preview parameter)' function. This makes it possible for unauthenticated attackers to leverage arbitrary script code and execute via forged request granted they can trick a site administrator 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')
Reaching this weakness in Soundy Audio Playlist <= 4.6 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. No fixed build of this plugin is recorded for Soundy Audio Playlist yet, so installs running <= 4.6 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to Soundy Audio Playlist: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
