CVE-2025-47073
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When users visit pages containing these compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM instances for content management.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites.
Likely Case
Low-privileged users could escalate privileges, steal other users' session data, or manipulate content displayed to visitors.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented despite the underlying code flaw.
🎯 Exploit Status
Requires authenticated low-privileged access. Exploitation involves injecting scripts into form fields that persist in the system.

🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or OSGi console. Versions 6.5.22 and earlier are vulnerable.Check Version:
curl -s http://aem-host:port/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
After updating, verify version is 6.5.23 or later and test form fields with XSS payloads to confirm they're properly sanitized.📡 Detection & Monitoring
