Vulnerability Overview

The Contact Form Entries plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 1.2.9 when outputting to a CSV file. This allows low-level attackers to embed untrusted input contact forms that will be present in 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 interaction from a victim user. 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 1.3.0, or a newer patched version
