CVE-2025-46987
📋 TL;DR
This stored 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 6.5.22 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.
Likely Case
Attackers with low privileges could steal session tokens from other users, perform limited unauthorized actions, or deploy basic phishing attacks.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented despite the underlying code flaw.
🎯 Exploit Status
Requires authenticated low-privileged access. Exploitation is straightforward once vulnerable fields are identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html
Restart Required: Yes
Instructions:
1. Download Adobe Experience Manager 6.5.23 or later from Adobe's official distribution. 2. Follow Adobe's upgrade documentation for your deployment type. 3. Apply the update to all affected instances. 4. Restart the AEM service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize user input in form fields
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allImplement strict CSP headers to mitigate XSS impact
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to HTTP headers
🧯 If You Can't Patch
- Restrict low-privileged user access to content creation/modification interfaces
- Implement web application firewall rules to block XSS payload patterns
🔍 How to Verify
Check if Vulnerable:
Check AEM version via OSGi console or CRXDE. If version is 6.5.22 or earlier, system is vulnerable.Check Version:
curl -u admin:admin http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify version is 6.5.23 or later. Test form fields with safe XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual content modifications by low-privileged users
- JavaScript payloads in request logs
- Multiple failed XSS attempts
Network Indicators:
- Suspicious JavaScript in HTTP POST requests to form endpoints
- Unexpected external script loads from AEM pages
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
