CVE-2025-46949
📋 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 AEM versions 6.5.22 and earlier.
💻 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 install malware on victim systems.
Likely Case
Session hijacking, credential theft, or defacement of AEM content pages 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 authenticated low-privileged access to inject scripts into vulnerable 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 AEM 6.5.23 or later from Adobe distribution. 2. Follow Adobe's upgrade guide for your deployment type (author/publish). 3. Apply hotfix if using older version. 4. Restart AEM instances.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation for all form fields to reject malicious scripts.
Custom AEM servlet filter or Sling filter configuration required
Content Security Policy
allImplement strict CSP headers to prevent script execution from untrusted sources.
Add 'Content-Security-Policy' header via dispatcher or web server configuration
🧯 If You Can't Patch
- Restrict low-privileged user access to content editing capabilities
- Implement web application firewall (WAF) rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. Versions 6.5.22 or earlier are vulnerable.Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfoVerify Fix Applied:
Verify AEM version is 6.5.23 or later and test form fields for script injection.📡 Detection & Monitoring
Log Indicators:
- Unusual content modifications
- Script tags in form submissions
- Multiple failed XSS attempts
Network Indicators:
- Suspicious POST requests with script payloads to AEM forms
SIEM Query:
source="aem-access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
