Vulnerability Overview

The Post Form – Registration Form – Profile Form for User Profiles – Frontend Content Forms for User Submissions (UGC) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'buddyforms_nav' shortcode in all versions up to, and including, 2.8.15 due to insufficient input sanitization and output escaping on user supplied attributes. 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 2.8.16, 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.
