CVE-2025-64875
📋 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 6.5.23 and earlier.

📦 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 web content 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 vulnerable form fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.24 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html
Restart Required: Yes

🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution from untrusted sources.
Add 'Content-Security-Policy' header with appropriate directives in web server configuration
Input Validation and Output Encoding
allImplement server-side validation and proper output encoding for all user inputs.
Configure AEM to use OWASP Java Encoder or similar libraries for output encoding
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities
- Implement web application firewall (WAF) rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console/status-productinfo) or CRX Package Manager.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify version is 6.5.24 or later and test form fields with XSS payloads to confirm they're properly sanitized.📡 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 common XSS payload patterns to form endpoints
SIEM Query:
