Assigner: Wordfence

Description

The EmbedPress – PDF Embedder, 3D PDF FlipBook, Google Reviews, YouTube Videos, Upload & Embed PDF documents plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'slidesShow' Block Attribute in all versions up to, and including, 4.6.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The slidesShow block attribute is interpolated into an unquoted data-carousel-options HTML attribute, allowing a payload containing spaces to break out of the attribute and inject additional DOM attributes such as onfocus event handlers onto the wrapper element.

Attack-Flow Graph

Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the EmbedPress WordPress plugin. It allows authenticated attackers with contributor-level access or higher to inject malicious scripts into web pages via the 'slidesShow' block attribute. The flaw exists due to insufficient input sanitization and output escaping, enabling attackers to break out of HTML attributes and inject harmful code that executes when users view the page.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the EmbedPress plugin (versions up to 4.6.6) for malicious scripts in the slidesShow block attribute. Check for unauthorized changes in page content or unexpected DOM attributes like onfocus handlers. Use WordPress admin access logs to identify contributors uploading suspicious content.

Impact Analysis

If exploited, this vulnerability could allow attackers to steal user sessions, deface websites, or redirect visitors to malicious sites. Users with contributor-level access or above on a WordPress site using the vulnerable plugin could compromise the site and its visitors.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA by enabling unauthorized access to user data, potential data breaches, or loss of data integrity. Organizations may face legal penalties if user data is compromised due to this flaw.

Mitigation Strategies

Immediately update the EmbedPress plugin to the latest version beyond 4.6.6. Remove or restrict contributor-level access to untrusted users. Scan WordPress sites for injected scripts using security plugins like Wordfence. Review and sanitize all block attributes, especially slidesShow, for malicious payloads.
