At a glance

CVE-2022-41616 is a medium-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the Export Users Data CSV WordPress plugin, affecting versions <= 2.1. It carries a CVSS score of 6.0 (reachable over the network). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.2; sites on affected versions should update now. Disclosed November 2022, reported by Kévin Mosbahi (Mika).

Vulnerability Overview

The Export Users Data CSV plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 2.1. This allows subscriber-level attackers to embed untrusted input into exported CSV files, which 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, and no interaction from a victim user.

CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Remediation

Update to version 2.2, 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. None of that substitutes for the fix: Export Users Data CSV 2.2 closes this, and updating the plugin is the step that ends it.
