Vulnerability Overview

The Export Post Info plugin for WordPress is vulnerable to CSV Injection. This allows authenticated users with author permissions or higher, to inject commands that the plugin will include when generating a CSV file for export. If a victim opens the malicious CSV file on a vulnerable platform these commands could be executed on their local machine.

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-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 1.2.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Author 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 Post Info 1.2.1 closes this, and updating the plugin is the step that ends it.
