Executive Summary

The Betheme WordPress theme has a stored Cross-Site Scripting (XSS) vulnerability in its 'icon_box_2' shortcode. This flaw exists in versions up to 28.4 due to insufficient input sanitization and output escaping on user-supplied attributes. Authenticated attackers with contributor-level access or higher can inject malicious scripts into pages.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using Betheme versions up to 28.4 for the 'icon_box_2' shortcode with unsanitized user input. Check WordPress admin panels for suspicious scripts in pages or posts. Use security plugins like Wordfence to scan for XSS vulnerabilities.

Impact Analysis

This vulnerability allows attackers to inject malicious scripts into your WordPress site. If exploited, these scripts can execute whenever a user accesses the affected page, potentially stealing user data, session cookies, or performing actions on behalf of users.

Compliance Impact

This vulnerability allows authenticated attackers with contributor-level access to inject arbitrary scripts into pages. This could lead to unauthorized data access, modification, or exfiltration, which may violate GDPR (data protection) and HIPAA (health data security) requirements for safeguarding sensitive information.

Mitigation Strategies

Update Betheme to version 28.4.1.1 or later immediately. Remove or restrict contributor-level access to untrusted users. Use security plugins to monitor and block XSS attempts. Review all pages and posts for injected scripts.
