CVE-2025-64825
📋 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 victims browse pages containing these compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM instances for content management.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or deploy additional malware through client-side attacks.
Likely Case
Session hijacking, credential theft, or defacement of web content through injected scripts.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access to vulnerable form fields.
🛠️ 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 AEM 6.5.24 or later from Adobe's distribution portal. 2. Follow Adobe's upgrade documentation for your deployment type (author/publish). 3. Apply the update and restart all AEM instances. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add to web server configuration: Content-Security-Policy: default-src 'self'; script-src 'self'
Input Validation Rules
allAdd server-side validation for all form fields
Implement input validation in AEM components using Java validation frameworks
🧯 If You Can't Patch
- Restrict low-privileged user access to content editing capabilities
- 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-productinfoVerify Fix Applied:
Confirm AEM version is 6.5.24 or later and test form fields for XSS payload acceptance.📡 Detection & Monitoring
Log Indicators:
- Unusual content modifications by low-privileged users
- Script tags in content repository entries
Network Indicators:
- Suspicious JavaScript payloads in HTTP POST requests to form endpoints
SIEM Query:
source="aem-access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
