CVE-2025-46894
📋 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.
💻 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
Attackers with low privileges could steal user session data, perform limited actions within the application, or deploy basic phishing attacks.
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 low-privileged access to vulnerable form fields. The vulnerability is well-understood (CWE-79) with common exploitation patterns.
🛠️ 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 installation.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize user input in form fields
Configure AEM's XSS protection filters via OSGi configuration
Content Security Policy
allImplement Content Security Policy headers to restrict script execution
Add 'Content-Security-Policy' header to HTTP responses
🧯 If You Can't Patch
- Restrict low-privileged user access to content creation and editing capabilities
- Implement web application firewall (WAF) rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or system/console/status-productinfo endpoint. If version is 6.5.22 or earlier, the system is vulnerable.
Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'
Verify Fix Applied:
Verify AEM version is 6.5.23 or later. Test form fields with safe XSS payloads to confirm they are properly sanitized.
