Vulnerability Overview

The Generate PDF using Contact Form 7 plugin for WordPress is vulnerable to Cross-Site Request Forgery to Arbitrary File Upload in versions up to, and including, 4.1.2. This is due to missing nonce validation and missing file type validation in the 'wp_cf7_pdf_dashboard_html_page' function. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE-2024-37555 is a duplicate of this issue.

Technical Analysis

REMEDIATION: Update to version 4.1.3, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
