CVE-2025-47051
📋 TL;DR
A 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. This affects Adobe Experience Manager versions 6.5.22 and earlier.

📦 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 install malware on victim systems.
Likely Case
Session hijacking, credential theft, defacement of web pages, or data exfiltration from user browsers.
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 and knowledge of 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. Download Adobe Experience Manager 6.5.23 or later from Adobe's official distribution. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update and restart all AEM instances.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources and prevent inline script execution.
Add 'Content-Security-Policy' header with appropriate directives in web server configuration
Input Validation and Output Encoding
allImplement server-side validation and proper output encoding for all user inputs in form fields.
Configure AEM's XSS protection filters and validate all form submissions
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields and components
- Implement web application firewall (WAF) rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via admin console or by examining the CRX package manager version.Check Version:
Access AEM admin console at /system/console/status-productinfo or check CRX package managerVerify Fix Applied:
Verify AEM version is 6.5.23 or later and test form fields with XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
