Overview

The vulnerability CVE-2021-24431 affects the WordPress plugin Language Bar Flags versions 1.0.8 and below. The vulnerability was discovered by Vinay Bhuria and was publicly disclosed on August 16, 2021. It combines Cross-Site Request Forgery (CSRF) and Stored Cross-Site Scripting (XSS) vulnerabilities in the plugin's settings management functionality (WPScan).

Technical details

The vulnerability stems from two main issues: the absence of CSRF protection when saving plugin settings and inadequate sanitization or escaping of these settings when generating the flag bar in the frontend. The vulnerability has been assigned a CVSS score of 7.1 (High) and is classified under CWE-79 and CWE-352 for XSS and CSRF respectively (WPScan).

Impact

When exploited, this vulnerability allows attackers to manipulate a logged-in administrator into changing the plugin settings and inject malicious Cross-Site Scripting payloads. These payloads are then executed in the frontend, affecting all users who visit the website (WPScan).

Mitigation and workarounds

As of the last update, there is no known fix available for this vulnerability in the Language Bar Flags plugin (WPScan).
