CVE-2025-64801
📋 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. 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, deface websites, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Attackers with low privileges could steal session tokens from other users, perform unauthorized actions within their permission scope, or deface specific content areas.
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. The vulnerability is stored/persistent, making exploitation easier once injected.
🛠️ 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 strict input validation and output encoding for all form fields to prevent script injection.
Configure AEM's XSS protection filters via OSGi console or configuration files
Content Security Policy
allImplement Content Security Policy headers to restrict script execution sources.
Add CSP headers via Apache/nginx configuration or AEM dispatcher
🧯 If You Can't Patch
- Restrict low-privileged user access to content editing capabilities
- Implement web application firewall 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:
Check via AEM welcome page or CRXDE Lite: /libs/cq/core/content/welcome.htmlVerify Fix Applied:
Verify AEM version is 6.5.24 or later. Test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual content modifications by low-privileged users
- JavaScript payloads in content audit logs
- Multiple failed XSS attempts
Network Indicators:
- Unexpected script tags in HTTP responses
- Suspicious content submissions to form endpoints
SIEM Query:
source="aem-audit.log" AND ("script" OR "javascript" OR "onload" OR "onerror") AND user_privilege="low"
