CVE-2025-47065
📋 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 through the compromised browser sessions.
Likely Case
Attackers with low privileges (like content authors) could escalate privileges by stealing admin credentials, deface websites, or steal sensitive data from users who view the compromised pages.
If Mitigated
With proper input validation and output encoding controls, the vulnerability would be prevented, though the underlying code flaw would still exist until patched.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields. The vulnerability is well-understood (stored XSS) making exploitation straightforward for attackers with access.
🛠️ 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 the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize form field inputs before processing
Configure AEM's XSS Protection API to filter malicious scripts from form submissions
Content Security Policy
allImplement strict CSP headers to prevent execution of injected scripts
Add 'Content-Security-Policy' header with script-src directives limiting script sources
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block XSS payloads in form submissions
- Restrict low-privileged user access to form editing capabilities and implement approval workflows for content changes
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or CRXDE Lite. Versions 6.5.22 and earlier are vulnerable.Check Version:
Navigate to AEM Welcome screen or use CRXDE Lite to check version informationVerify Fix Applied:
Verify AEM version is 6.5.23 or later and test form fields with basic XSS payloads to ensure they're properly sanitized.📡 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 payloads in form parameters
- Unexpected outbound connections from AEM server
SIEM Query:
source="aem_logs" AND ("<script>" OR "javascript:" OR "onload=" OR "onerror=")
