At a glance

CVE-2024-11613 is a critical-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the Iptanus File Upload WordPress plugin, affecting versions <= 4.24.15. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 4.25.0; sites on affected versions should update now. Disclosed January 2025, reported by abrahack.

Vulnerability Overview

The WordPress File Upload plugin for WordPress is vulnerable to Remote Code Execution, Arbitrary File Read, and Arbitrary File Deletion in all versions up to, and including, 4.24.15 via the 'wfu_file_downloader.php' file. This is due to lack of proper sanitization of the 'source' parameter and allowing a user-defined directory path. This makes it possible for unauthenticated attackers to execute code on the server.

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 confidentiality, integrity, availability — full site compromise territory.

CWE-94: Improper Control of Generation of Code ('Code Injection')

Iptanus File Upload <= 4.24.15 carries this weakness at source, and reaching it takes no account at all. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For Iptanus File Upload the fix is 4.25.0: builds <= 4.24.15 are affected, anything from 4.25.0 onward is not.

Remediation

Update to version 4.25.0, 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. 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: Iptanus File Upload 4.25.0 closes this, and updating the plugin is the step that ends it.
