CVE-2025-64623
📋 TL;DR
Adobe Experience Manager versions 6.5.23 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When users visit pages with these compromised fields, their browsers execute the attacker's JavaScript, 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 if combined with other vulnerabilities.
Likely Case
Attackers steal user session cookies, perform actions on behalf of authenticated users, or capture sensitive form data submitted by users.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw remains until patched.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields; stored XSS means payload persists until cleaned
🛠️ 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 was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize all user input before processing
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allImplement strict CSP headers to prevent script execution from untrusted sources
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to HTTP response headers
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payload patterns
- Disable or restrict low-privileged user access to vulnerable form fields and components
🔍 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 vulnerableCheck Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify AEM version is 6.5.24 or later; test form fields with basic XSS payloads to confirm sanitization📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script tags
- Requests containing common XSS payload patterns like <script>, javascript:, or onerror=
Network Indicators:
- HTTP requests with suspicious parameters containing script elements
- Outbound connections from AEM to unexpected domains following form submissions
SIEM Query:
source="aem-access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
