At a glance

This record tracks a high-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the Dewplayer WordPress plugin, affecting versions *. It carries a CVSS score of 8.6 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed December 2013, reported by Eugene Dokukin.

Vulnerability Overview

The Dewplayer plugin <= 1.2 and Advanced Dewplayer plugin < 1.5 for WordPress are vulnerable to Content Spoofing/Injection. This is due to lack of sanitization of the 'mp3', 'file', 'sound', and 'son' parameters in the dewplayer.swf file. This makes it possible for unauthenticated attackers to inject malicious content into legitimate content 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, and no interaction from a victim user. A successful exploit has high impact on integrity.

CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

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 Dewplayer: 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.
