At a glance

CVE-2022-1539 is a high-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the Exports and Reports WordPress plugin, affecting versions <= 0.9.1. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 0.9.2; sites on affected versions should update now. Disclosed May 2022, reported by websafe2021.

Vulnerability Overview

The Exports and Reports plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 0.9.1 via the CSV export functionality. This allows 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, 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.

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 0.9.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Exports and Reports: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Exports and Reports 0.9.2 closes this, and updating the plugin is the step that ends it.
