CVE-2025-64792
📋 TL;DR
Adobe Experience Manager versions 6.5.23 and earlier contain a stored XSS vulnerability that allows low-privileged attackers to inject malicious JavaScript into form fields. When victims browse 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.
Likely Case
Low-privileged attackers steal session cookies or credentials from users who view compromised pages, enabling account takeover and lateral movement.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized, preventing execution while maintaining form functionality.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access; stored XSS allows persistent attacks affecting multiple users.
🛠️ 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 distribution portal. 2. Apply the service pack following Adobe's installation guide. 3. Restart all AEM instances. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize form field inputs before storage.
Configure AEM's XSS protection filters via OSGi console or repository configuration
Content Security Policy
allImplement CSP headers to restrict script execution from unauthorized sources.
Add 'Content-Security-Policy' header via dispatcher or web server configuration
🧯 If You Can't Patch
- Restrict low-privileged user access to form creation and editing capabilities
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console; if version is 6.5.23 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 6.5.24 or later and test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
