CVE-2025-64808
📋 TL;DR
Adobe Experience Manager versions 6.5.23 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When users visit pages containing these compromised fields, their browsers execute the attacker's JavaScript. 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 session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites, potentially leading to full account compromise.
Likely Case
Attackers with low privileges could modify content to include malicious scripts, potentially stealing session tokens or performing limited actions as victims.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized, preventing execution in user browsers.
🎯 Exploit Status
Exploitation requires authenticated access with content creation/modification privileges.
🛠️ 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
Instructions:
1. Download AEM 6.5.24 or later from Adobe's distribution portal. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update package. 4. Restart AEM services. 5. Verify successful upgrade.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize user input in form fields
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allImplement strict CSP headers to prevent script execution from untrusted sources
Add 'Content-Security-Policy: script-src 'self'' to HTTP response headers
🧯 If You Can't Patch
- Restrict user permissions to only necessary content creation/modification areas
- Implement web application firewall (WAF) rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. If version is 6.5.23 or earlier, system is vulnerable.
Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'
Verify Fix Applied:
After patching, verify version is 6.5.24 or later and test form fields with XSS payloads to ensure they're properly sanitized.
📡 Detection & Monitoring
Log Indicators:
- Unusual content modifications by low-privileged users
- Script tags or JavaScript in form field submissions
Network Indicators:
- Unexpected script loads in page responses
- Suspicious outbound connections from user browsers
SIEM Query:
source="aem-access.log" AND ("script" OR "javascript" OR "onload" OR "onerror") AND user!="admin"
