CVE-2025-46947
📋 TL;DR
A stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into form fields. When victims browse pages containing the compromised fields, their browsers execute the attacker's code. This affects Adobe Experience Manager versions 6.5.22 and earlier.
💻 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 ransomware through the victim's browser.
Likely Case
Session hijacking, credential theft, or defacement of web pages through injected content.
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 inject scripts into vulnerable form fields.
🛠️ 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. Backup your AEM instance. 2. Download and apply Adobe Experience Manager 6.5.23 or later from Adobe's distribution portal. 3. Restart the AEM service. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution from untrusted sources.
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to web server configuration
Input Validation Filter
allDeploy a servlet filter to sanitize form field inputs before processing.
Implement Java filter using OWASP Java Encoder library to encode user inputs
🧯 If You Can't Patch
- Restrict low-privileged user access to form 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 6.5.22 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:
Verify AEM version is 6.5.23 or later and test form fields with XSS payloads to ensure they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags
- JavaScript payloads in request parameters
- Multiple failed XSS attempts
Network Indicators:
- HTTP requests containing <script> tags or javascript: URIs in form data
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
