CVE-2025-64852
📋 TL;DR
This stored 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, potentially compromising user sessions or stealing sensitive data. Organizations running 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 credentials, hijack user sessions, deface websites, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers with low privileges could steal user session cookies, perform actions on behalf of authenticated users, or capture sensitive form data.
If Mitigated
With proper input validation and output encoding, the impact is limited to unsuccessful injection attempts that get sanitized before execution.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. The vulnerability is in form fields where user input isn't properly sanitized.
🛠️ Fix & Mitigation
✅ Official Fix

🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize all user input before processing
Implement custom Java servlet filter with input validation logic
Content Security Policy
allImplement strict CSP headers to limit script execution
Add 'Content-Security-Policy: script-src 'self'' to HTTP headers
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads
- Disable or restrict low-privileged user access to vulnerable form fields
🔍 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 -k https://[aem-host]:[port]/system/console/status-productinfo | grep 'Adobe Experience Manager'
Verify Fix Applied:
After patching, verify version is 6.5.24 or later. Test form fields with XSS payloads to ensure sanitization.
