CVE-2025-64541
📋 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 compromised 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, redirect users to malicious sites, or deploy ransomware through the compromised AEM instance.
Likely Case
Attackers with low privileges steal session cookies from higher-privileged users, gaining unauthorized access to sensitive content and administrative functions.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before reaching user browsers, preventing exploitation.
🎯 Exploit Status
Exploitation requires authenticated access but only low privileges. Stored XSS vulnerabilities are commonly weaponized in real attacks.
🛠️ 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 before processing
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allDeploy strict Content Security Policy headers to restrict script execution
Add 'Content-Security-Policy: script-src 'self'' to HTTP response headers
🧯 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 authoring and form submission capabilities
🔍 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 safe XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript code
- Multiple failed login attempts followed by form submissions
Network Indicators:
- HTTP requests containing script tags in form parameters
- Outbound connections to suspicious domains from AEM server
SIEM Query:
source="aem_logs" AND ("<script>" OR "javascript:" OR "onload=" OR "onerror=")
