CVE-2025-47047
📋 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 6.5.22 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, potentially leading to full system compromise if combined with other vulnerabilities.
Likely Case
Attackers with low privileges could steal session cookies of other users, perform limited unauthorized actions within the application, or deface specific pages containing the vulnerable fields.
If Mitigated
With proper input validation and output encoding controls, the risk is reduced to minimal, though the vulnerability still exists in the codebase.
🎯 Exploit Status
Exploitation requires low-privileged access to inject scripts into vulnerable form fields. The attack is stored/persistent, affecting all users who view the compromised content.
🛠️ 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 to all affected instances. 4. Restart the AEM service to complete the installation.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation on all form fields and ensure proper output encoding when displaying user content.
Content Security Policy (CSP)
allImplement a strict Content Security Policy header to mitigate XSS impact by restricting script execution sources.
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in form submissions
- Restrict low-privileged user access to form editing capabilities and implement strict content review workflows
🔍 How to Verify
Check if Vulnerable:
Check your Adobe Experience Manager version via the AEM welcome screen or system console. If version is 6.5.22 or earlier, you are vulnerable.Check Version:
Access AEM welcome screen at http://[host]:[port]/welcome.html or check CRXDE Lite at /crx/deVerify Fix Applied:
After patching, verify the version shows 6.5.23 or later. Test form fields with safe XSS payloads to confirm proper sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions containing script tags or JavaScript code
- Multiple failed login attempts followed by form submissions
Network Indicators:
- HTTP requests containing script tags or JavaScript in form parameters
- Unusual outbound connections from user browsers after visiting AEM pages
