📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

High-privileged attacker steals admin credentials, performs session hijacking, or deploys ransomware through malicious scripts.

🟠

Likely Case

Privileged user account compromise leading to data theft, defacement, or lateral movement within the AEM environment.

🟢

If Mitigated

Limited impact due to proper input validation, output encoding, and least privilege access controls.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires high-privileged credentials; stored XSS is straightforward once authenticated.

Add CSP headers to restrict script execution

Add 'Content-Security-Policy: script-src 'self'' to dispatcher/webserver config

🧯 If You Can't Patch

  • Restrict high-privilege accounts to essential personnel only
  • Implement web application firewall with XSS protection rules

🔍 How to Verify

Check if Vulnerable:

Check AEM version via Welcome screen (http://localhost:4502/libs/granite/core/content/login.html) or CRX Package Manager

Check Version:

curl -s http://localhost:4502 | grep 'AEM 6.5'

Verify Fix Applied:

Confirm version is 6.5.24+ and test form fields with XSS payloads

📡 Detection & Monitoring

Log Indicators:

  • Unusual form submissions with script tags
  • Multiple failed XSS attempts in request logs

Network Indicators:

  • HTTP requests containing <script> tags in form parameters
  • Unexpected outbound connections from AEM server

SIEM Query:

source="aem_access.log" AND ("<script" OR "javascript:" OR "onerror=")
