At a glance

CVE-2022-3605 is a high-severity Improper Neutralization of Formula Elements in a CSV File vulnerability in the WP CSV Exporter WordPress plugin, affecting versions <= 1.3.6. It carries a CVSS score of 7.7 (low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.3.7; sites on affected versions should update now. Disclosed November 2022, reported by Francesco Carlucci.

Vulnerability Overview

The WP CSV Exporter plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 1.3.6. This allows administrator-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. CVE-2022-38702 appears to be a duplicate of this vulnerability.

Technical Analysis

The vector marks this flaw as requiring local or adjacent access, with low attack complexity — no special timing or configuration is needed. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

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 1.3.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP CSV Exporter: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP CSV Exporter 1.3.7 closes this, and updating the plugin is the step that ends it.
