📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, perform actions as authenticated users, or redirect users to malicious sites, potentially leading to account compromise or data theft.

🟠

Likely Case

Attackers could perform limited session hijacking or deface content within the application context, though impact is constrained by user interaction requirement.

🟢

If Mitigated

With proper Content Security Policy (CSP) headers and input validation, impact is minimal as malicious scripts would be blocked or sanitized.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: LOW

🎯 Exploit Status

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

Exploitation requires low-privileged access and user interaction via crafted web page.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 6.5.23 or later

Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html

Restart Required: Yes

Instructions:

1. Download Adobe Experience Manager 6.5.23 or later from Adobe's distribution portal. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update to all affected instances. 4. Restart the AEM service.

🔧 Temporary Workarounds

Implement Content Security Policy

all

Add strict CSP headers to block inline scripts and restrict script sources.

Add 'Content-Security-Policy: script-src 'self'' to web server configuration

Input Validation Filter

all

Implement server-side input validation to sanitize DOM manipulation inputs.

Configure AEM's XSS protection filter via OSGi console

🧯 If You Can't Patch

  • Implement strict Content Security Policy headers to block inline scripts.
  • Restrict low-privileged user access to content authoring features.

🔍 How to Verify

Check if Vulnerable:

Check AEM version via CRXDE Lite or system console. If version is 6.5.22 or earlier, system is vulnerable.

Check Version:

curl -u admin:password http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'

Verify Fix Applied:

Verify AEM version is 6.5.23 or later and test DOM manipulation inputs are properly sanitized.

📡 Detection & Monitoring

Log Indicators:

  • Unusual DOM manipulation requests in access logs
  • JavaScript errors related to CSP violations

Network Indicators:

  • Requests with suspicious script tags in parameters
  • Unexpected redirects to external domains

SIEM Query:

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