💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.23 and earlier
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Requires low-privileged user account for exploitation. All deployment types (on-premise, cloud) are affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware via drive-by downloads.

🟠

Likely Case

Session hijacking, credential theft, or defacement of web content through injected scripts.

🟢

If Mitigated

Limited impact due to same-origin policy restrictions and requirement for user interaction.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires low-privileged attacker account and user interaction. DOM-based XSS typically requires specific payload crafting for target environment.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 6.5.24 or later

Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html

Restart Required: Yes

Instructions:

1. Download AEM 6.5.24+ from Adobe Distribution portal. 2. Apply service pack via Package Manager. 3. Restart AEM instance. 4. Verify update via /system/console/status-productinfo endpoint.

🔧 Temporary Workarounds

Content Security Policy

all

Implement strict CSP headers to restrict script execution sources

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

Input Validation Filter

all

Deploy custom servlet filter to sanitize user inputs

Implement javax.servlet.Filter to validate and encode user inputs before DOM processing

🧯 If You Can't Patch

  • Restrict low-privileged user access to minimum required functionality
  • Implement web application firewall with XSS protection rules

🔍 How to Verify

Check if Vulnerable:

Check AEM version via /system/console/status-productinfo endpoint or CRX Package Manager. If version is 6.5.23 or earlier, system is vulnerable.

Check Version:

curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'

Verify Fix Applied:

Confirm version is 6.5.24 or later via same endpoint. Test XSS payloads in user input fields to ensure sanitization.

📡 Detection & Monitoring

Log Indicators:

  • Unusual JavaScript payloads in request logs
  • Multiple failed login attempts followed by script-like requests
  • Requests with encoded script tags in parameters

Network Indicators:

  • Outbound connections to unknown domains following user interaction
  • Unusual Content-Type headers in responses

SIEM Query:

source="aem-access.log" AND ("<script" OR "javascript:" OR "onload=" OR "onerror=")
