Vulnerability Overview

The Request a Quote WordPress plugin through 2.3.8 does not validate uploaded CSV files, allowing unauthenticated users to attach a malicious CSV file to a quote, which could lead to a CSV injection once an admin download and open it

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-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

Update to version 2.3.9, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Request a Quote: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Request a Quote 2.3.9 closes this, and updating the plugin is the step that ends it.
