CVE-2025-64794
📋 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, deface websites, or redirect users to malicious sites, potentially leading to full account compromise and data theft.
Likely Case
Attackers with low privileges inject malicious scripts to steal session tokens or credentials from other users, enabling unauthorized access to sensitive content management functions.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized, preventing execution while maintaining normal functionality.
🎯 Exploit Status
Exploitation requires low-privileged access to inject scripts; typical XSS techniques apply.
🛠️ 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+ from Adobe Distribution. 2. Backup current instance. 3. Apply update via Package Manager. 4. Restart AEM services. 5. Verify update via /system/console/status-productinfo.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize form field inputs before processing.
Implement Java filter with OWASP Java Encoder library for XSS prevention
Content Security Policy
allDeploy strict CSP headers to restrict script execution sources.
Add 'Content-Security-Policy: script-src 'self'' to HTTP responses
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields via ACLs
- Implement WAF rules to block XSS payload patterns in form submissions
🔍 How to Verify
Check if Vulnerable:
Check AEM version via /system/console/status-productinfo; if version ≤6.5.23, instance 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 and test form fields with XSS payloads (e.g., <script>alert('test')</script>) to ensure sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags
- Error logs showing script injection attempts
Network Indicators:
- HTTP requests containing <script> tags in form parameters
- Unusual outbound connections from AEM to external domains
SIEM Query:
source="aem-access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
