Vulnerability Overview

Authenticated (administrator or higher role) Local File Inclusion (LFI) vulnerability in Wow-Company's Popup Box plugin <= 2.1.2 at WordPress.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')

Reaching this weakness in Popup Box <= 2.1.2 takes any authenticated account. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.

Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For Popup Box the fix is 2.2: builds <= 2.1.2 are affected, anything from 2.2 onward is not.

Remediation

Update to version 2.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Popup Box: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Popup Box 2.2 closes this, and updating the plugin is the step that ends it.
