CVE-2025-47085
📋 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. 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 administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites.
Likely Case
Low-privileged users could escalate privileges, steal session data from other users, or perform limited malicious actions within the application context.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw would remain.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. The vulnerability is in form fields where user input is not properly sanitized before being stored and displayed.
🛠️ 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 channels. 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 update.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side input validation and output encoding for all user-controllable form fields
Custom AEM component development with proper XSS protection
Content Security Policy (CSP)
allImplement strict CSP headers to mitigate XSS impact
Configure Apache/Dispatcher or AEM OSGi configuration for CSP headers
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields and components
- Implement web application firewall (WAF) rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via AEM Web Console (/system/console) or by examining the AEM installation directoryCheck Version:
Check CRX Package Manager or AEM Welcome page for version informationVerify Fix Applied:
Verify AEM version is 6.5.23 or later and test form fields for XSS payloads📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript payloads
- Multiple failed XSS attempts in access logs
Network Indicators:
- HTTP requests containing suspicious script payloads in form parameters
SIEM Query:
source="aem_access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
