CVE-2025-64802
📋 TL;DR
Adobe Experience Manager versions 6.5.23 and earlier contain a stored Cross-Site Scripting vulnerability that allows low-privileged attackers to inject malicious JavaScript into form fields. When victims visit pages containing the compromised fields, their browsers execute the attacker's code, potentially leading to session hijacking or data theft.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator sessions, compromise user accounts, deface websites, or redirect users to malicious sites, potentially leading to full system compromise if combined with other vulnerabilities.
Likely Case
Low-privileged attackers steal session cookies or credentials from users who interact with compromised form fields, enabling account takeover and lateral movement within the application.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though residual risk remains if other XSS vectors exist.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access; stored XSS typically has low complexity once vulnerable fields are identified.
🛠️ 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 Adobe Experience Manager 6.5.24 or later from Adobe's official distribution channels. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update to all affected instances. 4. Restart the AEM service to complete the installation.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize user input in form fields before storage.
Configure AEM's XSS protection filter via OSGi configuration: /system/console/configMgr/com.adobe.granite.xss.impl.XSSFilterImpl
Content Security Policy
allImplement strict Content Security Policy headers to mitigate script execution.
Add CSP headers via Apache/nginx configuration or AEM dispatcher rules
🧯 If You Can't Patch
- Implement web application firewall rules to block XSS payloads in form submissions
- Disable or restrict low-privileged user access to vulnerable form fields through permission controls
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console; versions 6.5.23 or earlier are vulnerable.Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfo.json | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify installation of version 6.5.24 or later and test form fields with XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions containing script tags or JavaScript code in request parameters
- Multiple failed XSS attempts from single IP addresses
Network Indicators:
- HTTP requests with suspicious parameters containing <script> tags or JavaScript functions
SIEM Query:
source="aem_access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
