CVE-2025-64814
📋 TL;DR
A 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. This affects Adobe Experience Manager versions 6.5.23 and earlier.
💻 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, redirect users to malicious sites, or install malware through drive-by downloads.
Likely Case
Attackers with low privileges could steal session cookies of other users, perform limited actions within their permissions, or deface content.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw remains.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. The vulnerability is in form fields where user input is not properly sanitized.
🛠️ 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 the AEM instance. 4. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize user input in form fields
Implement Java servlet filter with input validation logic for vulnerable endpoints
Content Security Policy
allImplement strict CSP headers to limit script execution
Add 'Content-Security-Policy' header with script-src directives
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields and components
- Implement web application firewall (WAF) rules to 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 confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags
- Multiple failed XSS attempts in request logs
- Suspicious user input patterns in access logs
Network Indicators:
- HTTP requests containing script tags or JavaScript 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=")
