Vulnerability Overview

The wpDiscuz plugin for WordPress is vulnerable to Arbitrary Content Injection in versions up to, and including, 7.6.10. The cause of this vulnerability is undisclosed at this time. However, this vulnerability makes it possible for unauthenticated attackers to inject new content onto the website, possibly through the manipulation of posts to create new web pages, spam, or phishing.

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-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

Update to version 7.6.11, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Comments 7.6.11 closes this, and updating the plugin is the step that ends it.
