CVE-2025-47093
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored Cross-Site Scripting vulnerability that allows low-privileged attackers to inject malicious JavaScript into form fields. When victims browse pages containing the compromised fields, their browsers execute the attacker's code. This affects organizations using vulnerable AEM instances for content management.
💻 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, redirect users to malicious sites, or deploy additional malware payloads.
Likely Case
Attackers with low privileges could hijack user sessions, deface content, or steal sensitive data from users who interact with compromised pages.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw would still exist.
🎯 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 AEM 6.5.23 or later from Adobe's distribution portal. 2. Backup current instance and content. 3. Apply the update following Adobe's upgrade documentation. 4. Restart the AEM instance. 5. Verify functionality post-upgrade.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize form field inputs before storage.
Configure AEM's XSS protection filters via OSGi console or configuration files
Content Security Policy
allImplement strict CSP headers to limit script execution sources.
Add 'Content-Security-Policy' header via web server configuration or AEM dispatcher
🧯 If You Can't Patch
- Restrict low-privileged user access to form creation and editing capabilities
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or CRXDE Lite. Versions 6.5.22 or earlier are vulnerable.Check Version:
Check AEM welcome page or use: curl -k https://aem-instance:4502/libs/granite/core/content/login.html | grep 'AEM 6.5'Verify Fix Applied:
After patching, verify version is 6.5.23 or later. Test form fields with basic XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript code
- Multiple failed XSS attempts in request logs
Network Indicators:
- HTTP requests containing script injection patterns to form endpoints
SIEM Query:
source="aem_access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
