Attack-Flow Graph

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Sina Extension for Elementor WordPress plugin. It occurs because the plugin does not properly escape a Table widget setting before outputting it in an HTML attribute. This allows users with Contributor role or higher to inject malicious scripts that are stored on the server and executed when other users view the affected page.

Detection Guidance

Check the installed version of the Sina Extension for Elementor plugin. If it is between 3.7.1 and 3.10.3, the system is vulnerable. Use commands like 'wp plugin list' in WordPress or inspect the plugin files for version details.

Impact Analysis

If exploited, this vulnerability could allow attackers to steal user sessions, perform actions on behalf of users, or deface the website. Users with Contributor role or higher could inject scripts that run in the browsers of other users visiting the site, potentially leading to data theft or unauthorized actions.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing user data to unauthorized parties. GDPR requires protecting personal data, and HIPAA mandates safeguarding health information. A successful XSS attack could result in data breaches, violating these regulations and potentially leading to legal penalties.

Mitigation Strategies

Update the Sina Extension for Elementor plugin to version 3.10.4 or later immediately. If updating is not possible, consider disabling the plugin temporarily until an update is applied.
