💻 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 deploy additional malware payloads through the compromised browser sessions.
Likely Case
Session hijacking, credential theft, or defacement of web content through injected scripts, potentially leading to data breaches or unauthorized administrative actions.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy headers in place, though vulnerability still exists.
🎯 Exploit Status
Requires authenticated low-privileged access. Exploitation involves injecting scripts into vulnerable form fields that persist and execute when viewed.
🛠️ 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. Backup AEM instance and content. 2. Download and apply AEM 6.5.23 or later update from Adobe Package Manager. 3. Restart AEM instance. 4. Verify update installation through AEM welcome screen version check.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources and prevent inline script execution
Add 'Content-Security-Policy' header with appropriate directives to web server configuration
Input Validation Filter
allImplement server-side input validation for all form fields to sanitize user input
Configure AEM filters or servlet filters to sanitize form submissions
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via Welcome screen or CRX Package Manager. Versions 6.5.22 or earlier are vulnerable.Check Version:
Navigate to AEM welcome screen or check via CRX Package Manager interfaceVerify Fix Applied:
Verify AEM version is 6.5.23 or later. Test form fields with safe XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript code
- Multiple failed validation attempts on form fields
Network Indicators:
- HTTP requests containing script injection patterns to form endpoints
- Unusual outbound connections from AEM server following form submissions
