CVE-2025-64616
📋 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 using Adobe Experience Manager versions 6.5.23 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 could steal session cookies of other users, perform limited actions within their permission scope, or deface specific content areas.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw would still exist.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. Stored XSS typically has lower complexity than reflected XSS.
🛠️ 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. 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 Filter
allImplement server-side input validation to sanitize form field inputs before processing.
Configure AEM's XSS protection filters to validate vulnerable form fields
Content Security Policy
allImplement strict Content Security Policy headers to limit script execution.
Add 'Content-Security-Policy' header with script-src directives
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in form submissions
- Disable or restrict access to vulnerable form fields for low-privileged users
🔍 How to Verify
Check if Vulnerable:
Check AEM version via AEM Web Console (/system/console) or by examining the CRX package manager. Versions 6.5.23 and earlier are vulnerable.Check Version:
curl -s http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify the AEM version is 6.5.24 or later. Test form fields that were previously vulnerable to ensure they properly sanitize input.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript payloads
- Multiple failed validation attempts on form fields
Network Indicators:
- HTTP requests containing script tags in form parameters
- Unusual outbound connections from user browsers after form submissions
SIEM Query:
source="aem-access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
