Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the Countdown, Coming Soon, Maintenance WordPress plugin versions 3.0.8 and below. It allows users with Author-level access or higher to inject malicious JavaScript by exploiting missing authorization checks and weak output sanitization that permits script tags. The injected scripts execute when the affected content is viewed on the front end or in admin sessions.

Detection Guidance

Check if the Countdown, Coming Soon, Maintenance WordPress plugin version 3.0.8 or below is installed. Inspect plugin files for unauthorized script tags in countdown data. Review user roles with Author access or higher for suspicious activity.

Impact Analysis

An attacker with Author-level access could inject scripts to steal cookies, session tokens, or sensitive data from other users viewing the site. They could also perform actions on behalf of users, deface the site, or redirect visitors to malicious sites. Admin sessions viewing the affected content could also be compromised.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. A successful exploit may result in data breaches, triggering compliance violations and potential legal penalties.

Mitigation Strategies

Update the plugin to the latest version immediately. Remove or restrict Author-level user access if not required. Monitor for unusual script execution in frontend or admin sessions.
