At a glance

CVE-2024-13355 is a medium-severity Unrestricted Upload of File with Dangerous Type vulnerability in the OrderConvo WordPress plugin, affecting versions <= 13.2. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 13.3; sites on affected versions should update now. Disclosed January 2025, reported by 1337_Wannabe.

Vulnerability Overview

The Admin and Customer Messages After Order for WooCommerce: OrderConvo plugin for WordPress is vulnerable to limited file uploads due to insufficient file type validation in the upload_file() function in all versions up to, and including, 13.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload files on the affected site's server which may make remote code execution possible and is confirmed to make Cross-Site Scripting possible.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-434: Unrestricted Upload of File with Dangerous Type

OrderConvo <= 13.2 carries this weakness at upload_file(), and reaching it takes an account at Subscriber level or above. 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 OrderConvo the fix is 13.3: builds <= 13.2 are affected, anything from 13.3 onward is not.

Remediation

Update to version 13.3, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: 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: OrderConvo 13.3 closes this, and updating the plugin is the step that ends it.
