WordPress vulnerability analysis and mitigation
Overview
CVE-2022-4216 affects the WordPress plugin Chained Quiz versions 1.3.2 and below. The vulnerability was discovered by Muhammad Zeeshan and disclosed on December 2, 2022. This security issue received a CVSS score of 5.5 (Medium) with the vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N (Wordfence).
Technical details
The vulnerability stems from improper input sanitization where sanitizetextfield is used instead of escattr in multiple endpoints. The affected files include chained-quiz/controllers/completed.php and chained-quiz/views/completed.html.php. Multiple endpoints in the plugin are vulnerable to Admin Stored XSS even when DISALLOWUNFILTERED_HTML is set to true (GitHub Gist).
Impact
When exploited, the vulnerability allows an attacker to execute cross-site scripting (XSS) attacks that could potentially lead to adding a new admin user to the website. The attack requires an admin user to visit a specially crafted URL shared by the attacker (GitHub Gist).
Mitigation and workarounds
Website administrators should update the Chained Quiz plugin to a version newer than 1.3.2 which contains the security fixes (Wordfence).
