CVE-2025-47044
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored cross-site scripting vulnerability in form fields. Low-privileged attackers can inject malicious scripts that execute in victims' browsers when they visit compromised pages. This affects all organizations running vulnerable AEM instances.
💻 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.
Likely Case
Attackers with low privileges could escalate privileges, steal user data, or perform limited malicious actions within the application context.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented despite the underlying code flaw.
🎯 Exploit Status
Exploitation requires authenticated access to vulnerable form fields. Stored XSS means payload persists until cleaned.
🛠️ 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's distribution portal. 2. Apply the service pack following Adobe's upgrade documentation. 3. Restart all AEM instances. 4. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize form field inputs before processing
Implement Java servlet filter with OWASP Java Encoder library
Content Security Policy
allDeploy strict CSP headers to mitigate script execution even if XSS occurs
Add 'Content-Security-Policy' header with script-src restrictions
🧯 If You Can't Patch
- Restrict low-privileged user access to form creation and editing capabilities
- Implement web application firewall rules to block XSS payload patterns
🔍 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:
After patching, verify version is 6.5.23 or later. Test form fields with basic XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags
- Multiple failed XSS attempts in request logs
- Suspicious content creation by low-privileged users
Network Indicators:
- HTTP requests containing script injection patterns
- Unusual outbound connections from user browsers after visiting AEM pages
SIEM Query:
source="aem_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
