Vulnerability Overview

The Scheduled Announcements Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'height_settings', 'link_settings', 'order_settings', 'saw_id', 'scroll_settings', 'show_titles', 'speed_settings', 'text_settings', 'trans_settings, and 'width_settings' shortcode attributes in versions up to, and including, 0.2 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 1.0, 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.
