CVE-2025-47013
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When victims browse pages containing these fields, their browsers execute the attacker's scripts. This affects AEM versions 6.5.22 and earlier.
💻 Affected Systems
- Adobe Experience Manager
📦 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 AEM content pages through stored malicious scripts.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access; stored XSS typically has straightforward exploitation vectors.
🛠️ 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 AEM 6.5.23 or later from Adobe Distribution. 2. Apply the Service Pack or Cumulative Fix Pack. 3. Restart AEM instances. 4. Verify the update via AEM console.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement server-side validation and HTML encoding for all user inputs in form fields.
Content Security Policy
allDeploy strict CSP headers to restrict script execution sources.
Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields and components.
- Implement web application firewall (WAF) rules to block XSS payloads.
🔍 How to Verify
Check if Vulnerable:
Check AEM version via OSGi console (http://<host>:<port>/system/console/bundles) or CRX Package Manager.Check Version:
curl -s http://localhost:4502/system/console/bundles | grep 'Adobe Experience Manager'Verify Fix Applied:
Confirm version is 6.5.23 or later and test form fields with XSS payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags
- JavaScript payloads in request parameters
Network Indicators:
- HTTP requests containing <script> tags or JavaScript functions in form data
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
