CVE-2025-64822
📋 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, potentially leading to session hijacking or data theft. 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 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 users could steal session cookies from other users, perform actions on their behalf, or capture sensitive data entered into forms.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw would still exist until patched.
🎯 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. Follow Adobe's upgrade documentation for your specific 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 custom servlet filters to sanitize all user input before processing
Implement Java servlet filter with input validation logic for all form submissions
Content Security Policy
allImplement strict CSP headers to mitigate XSS impact
Add 'Content-Security-Policy' header with script-src directives limiting JavaScript sources
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in form submissions
- Restrict low-privileged user access to content editing capabilities and form submission endpoints
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. If version is 6.5.23 or earlier, the 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. Test form fields with basic XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript code
- Multiple failed XSS attempts in request logs
- Suspicious content creation/modification by low-privileged users
Network Indicators:
- HTTP requests containing script tags or JavaScript in form parameters
- Unusual spikes in form submission traffic
SIEM Query:
source="aem_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=") AND (form_submission OR content_edit)
