CVE-2025-47113
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored XSS vulnerability in form fields. Low-privileged attackers can inject malicious JavaScript that executes in victims' browsers when they visit compromised pages. 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 the compromised browser.
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 low-privileged access to inject scripts into vulnerable form fields. No authentication bypass needed beyond basic user permissions.
🛠️ 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 AEM instance and content. 2. Download and apply AEM 6.5.23+ update from Adobe Package Manager. 3. Restart AEM instance. 4. Verify update via AEM welcome screen version check.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add 'Content-Security-Policy' header with appropriate directives in web server configuration
Input Validation Filter
allDeploy servlet filter to sanitize form field inputs
Implement custom filter or use OWASP Java HTML Sanitizer library
🧯 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 Welcome screen (http://[host]:[port]/welcome) or CRX Package Manager for version 6.5.22 or earlierCheck Version:
curl -s http://[host]:[port]/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
Confirm version is 6.5.23+ via Welcome screen and test form fields with basic XSS payloads (e.g., <script>alert('test')</script>)📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script tags
- Error logs showing script execution failures in request parameters
Network Indicators:
- HTTP requests containing <script> tags in form parameters
- Unusual outbound connections from AEM server following form submissions
SIEM Query:
source="aem_access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
