Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the TMS Amelia ameliabooking plugin. It occurs due to improper neutralization of user input during web page generation, allowing attackers to inject malicious scripts that are stored on the server and executed when other users access the affected pages.

Detection Guidance

Detecting this Stored XSS vulnerability in TMS Amelia requires manual inspection of input fields and stored data. Check user input fields like booking forms, profile fields, or admin panels for improper input sanitization. Look for HTML/JavaScript tags in stored data that could execute scripts. Use browser developer tools to inspect network requests and responses for suspicious payloads.

Impact Analysis

An attacker could exploit this to steal user sessions, deface the website, or perform actions on behalf of users. Users with access to the system could have their credentials compromised or be redirected to malicious sites.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Organizations may face fines or legal consequences for failing to protect user data adequately.

Mitigation Strategies

Immediately update TMS Amelia to the latest version (2.4.12 or later). If an update is unavailable, disable the plugin temporarily. Implement strict input validation and output encoding for all user-supplied data. Use Content Security Policy (CSP) headers to mitigate XSS impact. Regularly audit stored data for malicious scripts.
