Attack-Flow Graph

Executive Summary

Adobe Experience Manager has a stored Cross-Site Scripting (XSS) vulnerability. A low-privileged attacker can inject malicious scripts into vulnerable form fields. When a victim visits the affected page, the malicious JavaScript executes in their browser.

Detection Guidance

Detecting this stored XSS vulnerability in Adobe Experience Manager requires manual inspection of form fields and input validation mechanisms. Check user-input fields like forms, comments, or search boxes for improper sanitization. Use browser developer tools to inspect submitted data and look for unescaped or improperly encoded content. Review server logs for unusual script tags or payloads in user submissions.

Impact Analysis

This vulnerability allows attackers to inject malicious scripts into web forms. If you interact with these forms, the scripts could steal your session cookies, redirect you to phishing sites, or perform actions on your behalf without your knowledge.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection requirements. For HIPAA, it may expose protected health information if exploited in healthcare systems, risking compliance with privacy rules.

Mitigation Strategies

Apply the latest Adobe Experience Manager security patches immediately. Implement strict input validation and output encoding for all user-supplied data. Configure Content Security Policy (CSP) headers to mitigate XSS impact. Restrict low-privileged user permissions to reduce attack surface. Monitor form submissions for suspicious payloads like script tags.
