Vulnerability Overview

The XX2WP Integration Tools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mxp_fb2wp_display_embed' shortcode in all versions up to, and including, 1.9.9. This is due to the plugin not properly sanitizing user input and output of the 'post_id' parameter. 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 2.0.0, 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.
