CVE-2024-3866: 
WordPress vulnerability analysis and mitigation

Overview

The Ninja Forms Contact Form plugin for WordPress contains a Reflected Self-Based Cross-Site Scripting vulnerability (CVE-2024-3866) via the 'Referer' header in versions up to and including 3.8.15. The vulnerability was discovered and disclosed on September 25, 2024, affecting the WordPress plugin ecosystem (NVD CVE).

Technical details

The vulnerability stems from insufficient input sanitization and output escaping of the 'Referer' header. It has been assigned a CVSS v3.1 base score of 6.1 (MEDIUM) by NIST and 4.7 (MEDIUM) by Wordfence, with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79: Improper Neutralization of Input During Web Page Generation (NVD CVE).

Impact

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts that execute when users perform specific actions, such as clicking on a link. However, successful exploitation requires the 'maintenance mode' to be enabled for the targeted form, which only occurs during required updates - a very short window of time (NVD CVE).

Mitigation and workarounds

The vulnerability has been patched in versions after 3.8.15. Users are advised to update to the latest version of the Ninja Forms plugin to mitigate this security risk (Wordpress Patch).
