📦 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
Attackers with low privileges could elevate their access, steal user session data, or perform limited malicious actions within the application context.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw would still exist.
🎯 Exploit Status
Requires authenticated low-privileged access to vulnerable form fields

Implement custom servlet filter or use AEM's built-in XSS protection features
Content Security Policy
allImplement strict CSP headers to limit script execution
Add Content-Security-Policy header to AEM dispatcher configuration
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. If version is 6.5.23 or earlier, system is vulnerable.Check Version:
curl -u admin:admin http://localhost:4502/system/console/status-productinfoVerify Fix Applied:
After patching, verify version is 6.5.24 or later and test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
