At a glance

CVE-2023-25035 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Quick Contact Form WordPress plugin, affecting versions <= 8.0.3.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 8.0.4; sites on affected versions should update now. Disclosed February 2023, reported by yuyudhn.

Vulnerability Overview

The Quick Contact Form plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.0.3.1. This is due to missing or incorrect nonce validation on the 'qcf_show_messages' and 'qcf_generate_csv' functions. This makes it possible for unauthenticated attackers to exfiltrate messages or the contact email list via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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. A successful exploit has high impact on confidentiality.

CWE-352: Cross-Site Request Forgery (CSRF)

Quick Contact Form <= 8.0.3.1 carries this weakness at qcf_show_messages, and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Quick Contact Form the fix is 8.0.4: builds <= 8.0.3.1 are affected, anything from 8.0.4 onward is not.

Remediation

Update to version 8.0.4, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Quick Contact Form: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Quick Contact Form 8.0.4 closes this, and updating the plugin is the step that ends it.
