CVE-2025-47037
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When victims browse pages containing these compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM versions for content management.
💻 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 deploy malware through client-side attacks.
Likely Case
Session hijacking, credential theft, or defacement of AEM content pages through client-side script execution.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy headers in place.
🎯 Exploit Status
Requires authenticated low-privileged access. Stored XSS typically has moderate exploitation complexity but low technical barrier.
🛠️ 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. Backup AEM instance. 2. Apply AEM 6.5.23 update via Package Manager. 3. Restart AEM instance. 4. Verify update via /system/console/status-productinfo endpoint.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filter to sanitize form field inputs before processing
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allAdd CSP headers to restrict script execution sources
Add 'Content-Security-Policy: script-src 'self'' to dispatcher or web server configuration
🧯 If You Can't Patch
- Restrict low-privileged user access to content authoring interfaces
- Implement web application firewall rules to block XSS payload patterns
🔍 How to Verify
Check if Vulnerable:
Check AEM version via /system/console/status-productinfo endpoint. If version is 6.5.22 or earlier, system is vulnerable.Check Version:
curl -k https://aem-host:port/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify version is 6.5.23 or later via same endpoint and test form fields with basic XSS payloads like <script>alert('test')</script>.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script tags
- Multiple failed XSS attempts in request logs
Network Indicators:
- HTTP requests containing <script> tags in form parameters
- Unusual outbound connections from AEM to external domains
SIEM Query:
source="aem_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
