CVE-2025-47087
📋 TL;DR
This 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. Organizations running Adobe Experience Manager versions 6.5.22 and earlier are affected.
💻 Affected Systems
- Adobe Experience Manager
📦 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, potentially leading to complete system compromise.
Likely Case
Attackers with low privileges steal session cookies or credentials from other users, escalate privileges, or perform unauthorized actions within the application.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before reaching user browsers, preventing exploitation.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. Stored XSS vulnerabilities are commonly exploited in real-world attacks.
🛠️ 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 official distribution channels. 2. Follow Adobe's upgrade documentation for your deployment type. 3. Apply the update to all affected instances. 4. Restart the AEM service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and proper output encoding for all user-controllable form fields to neutralize malicious scripts.
Implement Content Security Policy (CSP) headers
Use OWASP Java Encoder for output encoding
Configure input validation filters
Temporary Access Restrictions
allRestrict access to vulnerable form fields or disable them until patching can be completed.
Modify AEM permissions to restrict form field access
Disable vulnerable components via OSGi configuration
🧯 If You Can't Patch
- Implement strict Content Security Policy (CSP) headers to prevent script execution from untrusted sources
- Deploy a Web Application Firewall (WAF) with XSS protection rules and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or CRXDE Lite. Versions 6.5.22 and earlier are vulnerable.Check Version:
Navigate to http://[aem-host]:[port]/libs/granite/core/content/login.html and check version in page source, or use CRXDE Lite to check /apps/version.propertiesVerify Fix Applied:
Verify the AEM version is 6.5.23 or later and test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints
- Requests containing script tags or JavaScript payloads in form parameters
- Multiple failed XSS attempts from same IP
Network Indicators:
- HTTP requests with suspicious parameters containing script tags or JavaScript
- Unexpected outbound connections from AEM servers after form submissions
SIEM Query:
source="aem-access.log" AND ("<script" OR "javascript:" OR "onload=" OR "onerror=") AND status=200
