WP ULike <= 4.6.9 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode

Strategic Overview

Vulnerability Overview

The WP ULike plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wp_ulike' shortcode in all versions up to, and including, 4.6.9 due to insufficient input sanitization and output escaping on the user supplied 'wrapper_class' attribute. 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.

Technical Analysis

REMEDIATION: Update to version 4.7.0, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
