Vulnerability Overview

The Import WP – Import and Export WordPress data to XML or CSV files plugin for WordPress is vulnerable to arbitrary file upload via high level authenticated users in versions up to, and including, 2.4.5.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-434: Unrestricted Upload of File with Dangerous Type

Reaching this weakness in Import WP <= 2.4.5 takes any authenticated account. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.

If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For Import WP the fix is 2.4.6: builds <= 2.4.5 are affected, anything from 2.4.6 onward is not.

Remediation

Update to version 2.4.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Import WP: 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: Import WP 2.4.6 closes this, and updating the plugin is the step that ends it.
