Vulnerability Overview

The WP Users Exporter plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 1.4.2 via the 'Export Users' functionality. This makes it possible for authenticated attackers, such as a subscriber, to add untrusted input into profile information like First Names that will embed into the exported CSV file triggered by an administrator and can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

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-1236: Improper Neutralization of Formula Elements in a CSV File

The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Users Exporter: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
